Teaching Children Chess

Short games are a must for teaching Chess in almost any circumstance because of the time factor. When time is a factor a teacher must opt for the slash and dash of Mikhail Tal

There are many books containing short games, and most have seen action, but I have recently been adding short games to a folder and it was the resource used at the last minute when pressed into service with the clock ticking. Unfortunately, I did not copy the url and had no idea how it made it to the folder. This was disconcerting, to say the least. The game was played over a century ago. After the lesson my brain was racked in a futile attempt to locate the origin of the game. I put the game into both 365Chess and the ChessbaseDatabase in a futile attempt to locate the origin of the game, and was shocked to discover it was not found in either database. Flummoxed, I went to bed, still thinking about the game. After telling myself to put it outta my mind I was ready for sleep…When drifting off to nod heaven it hit me! It had to have come from the excellent website of Mark Crowther,

The Week In Chess, (https://theweekinchess.com/) the granddaddy of them all. Just about every morning the first Chess website to which I surf is the venerable TWIC, and each and every day there is a new Chess Puzzle which I attempt to solve. What follows are the pithy comments made to the youngsters as this writer attempted to teach the children well in a very limited amount of time.

1.e4 e5 2.Nc3 Nf6 3.Nf3 Nc6 4.Bc4 (4 d4 is the move) 4…Nxe4 5.O-O (Nxe4 is best) 5…Nxc3 6.bxc3 (Taking with the d-pawn is better) 6…d6 (6…e4!) 7.Re1 (7 Qe2!) 7…Be7 (“Castling looks good”) 8.d4 Bg4 (“Why not castle?”) 9.h3 Bxf3 (I would retreat the prelate to h5. Then comes the question, “What’s a prelate?”) 10.Qxf3 O-O 11.Bb5 (“I would play Be3 or Rb1.” Then comes feedback. “Which one”?) 11…Na5 (“11…exd4 must be examined”) 12.Bd3 (“How about 12 dxe5?”) 12…g6 13.Bh6 (“Again, 12 dxe5 is possible”) 13…Re8 14.dxe5 dxe5 (“Maybe 14…Bg5 or how about Bf8?”) 15.Rxe5

Black to move

15…Nc6 (“Looks like 15…Bf8 had to be played)

White to move

This is when the AW was ASTOUNDED when a little girl, who rarely speaks unless spoken to, erupted with, “QUEEN TAKES PAWN!!!” After gathering myself I asked, “Queen takes pawn, where?” She answered, “On f7.” I replied with another question, “And what does Queen takes pawn do?” She blurted, “It checks the King!” So I followed with, “Now say it right.” And she said, “Queen takes pawn on f7 with check!” All I said was, “YES! Ma’am.” That may have been the first time she had ever been addressed as “Ma’am.” She was giddy with excitement…and so was the AW.

The move played in the game has only scored 44%. My recommendation is to give them the Glek and play 5 g3!

AW Has Been HACKED!

The first notification that my email had been hacked came from Ilan in Moscow. The Legendary Ironman of Georgia Chess was next. Today I read the following at the magnificent website The Week In Chess:

Mark Crowther @MarkTWIC

In the chess world anyone know how to get in touch with Michael Bacon? His email has been hacked.

Mark Crowther @MarkTWIC Replying to @MarkTWIC

Someone who knows Michael Bacon needs to get in touch – via another method other than email as the person now in control of his account tried the Amazon Gift Card scam on me. https://www.theguardian.com/money/2020/oct/06/amazon-gift-card-scams-it-pays-to-know-who-your-real-friends-are … .

Sorry to bother you, hopefully you can help at the moment. I need to buy an Amazon gift card as a birthday gift for my nephew today but I can’t do this now as I’m currently away and I tried purchasing online but unfortunately no luck. Can you get it from any store around you? I’ll pay you back as soon as I am back. Your response would be greatly appreciated.

CF, by email

Nice try, CF, but we’re not falling for your attempt to defraud us. This email received by Consumer Champions is just one version of numerous scams doing the rounds involving Amazon gift cards. In one, links are shared on social media offering free Amazon vouchers or coupons. Users are invited to click on links to unlock significant discounts or receive free shopping on Amazon, before being asked for their personal or financial details.

Another is like this one – fraudsters hack into email accounts and submit apparently friendly requests for a favour. Often they claim to be a friend of a friend or even a work colleague. Sometimes they will ask you to buy a gift card online and forward it. We gather that local trading standards have been inundated with complaints from people who have been duped.

Amazon tells consumers to never answer an unsolicited email or phone offer they feel is too good to be true. And if you do fall victim, if you are an Amazon account holder contact its customer service or Action Fraud on 0300 123 2040.

Are Armageddon Chess Games Fair?

Armageddon:

1.
a. Bible In the book of Revelation, the place of the gathering of armies for the final battle before the end of the world.
b. The battle involving these armies.
2. A decisive or catastrophic conflict.

https://www.thefreedictionary.com/Armageddon

7th Norway Armageddon can be found at the Other events today section of the wonderful website, The Week In Chess, by Mark Crowther. (http://theweekinchess.com/) Mark has been providing Chess information since the “First issue 17th September 1994.” Yet Mark cannot display the games from the tournament in Norway. Why is that? Why does the Chess world continue repeatedly shooting itself in the foot? The reason is m-o-n-e-y. Refusing to allow Mark to display any kind of Chess information may be good for the organizers in the short term (although FIDE has continually proven the opposite yet continues attempting to gather all the spoils it can) but it cannot be good for the long term health of the organization. I refuse to follow any tournament not allowed to be displayed at TWIC. The Norway tournament was even easier to eschew because so-called “Armageddon Chess” is ridiculous. The fact organizers thought they had to resort to such nonsense is proof positive the Royal game of Chess in a decisive or catastrophic conflict with itself. I spent some time attempting to ascertain the name of the lunatic who first had the idea of playing Armageddon Chess, to no avail. Evidently there are enough lunatics involved with Chess to have helped facilitate foisting the Armageddon abomination upon we Chess fans. The research did produce a few items of interest. Consider something posted six months ago by BackrankPawn:

Are armageddon games fair?

In the unlikely event that the world championship goes to an armageddon game, would players prefer Black with 4 minutes and draw odds or white with 5 minutes? Is it roughly fair?

Why don’t they auction time for the draw odds?

*edit* I buried the lead. I wanted to figure out how much time the draw odds are worth. We could let the players decide by auctioning seconds for black and draw odds. Whoever spends more, gets that much time taken off but gets draw odds. Then there would be no complaints about coin flips.

Then there is this from Leonard Barden on Chess:

Armageddon divides fans while Magnus Carlsen leads again in Norway

Controversial speed format designed to prevent draws sparks a chaotic scramble at Altibox event and causes online uproar

Armageddon is a chess penalty shoot-out, a controversial format intended to prevent draws and to stimulate interesting play. It can also lead to chaotic scrambles where pieces fall off the board, players bang down their moves and hammer the clocks, and fractions of a second decide the result. That is what happened in Tuesday’s Levon Aronian v Alexander Grischuk game at Altibox Norway. The loser called it “among the top three most disappointing defeats in my life”.

In an Armageddon game White has more thinking time on the clock than Black but a draw on the board scores as a Black win. Normally White has five or six minutes and Black four or five for the entire game but in the current Altibox Norway tournament it is 10 against seven.

In response to growing complaints about too many draws the Altibox organisers made a controversial decision this year to limit classical games to four hours and to replay draws immediately as Armageddons. The scoring system is 2 points for a classical win, 1.5 for a classical draw and an Armageddon win, 0.5 for a classical draw and an Armageddon loss and 0 for a classical loss.

It’s the End of the World as We Know It (And I Feel Fine)
R.E.M.
Produced by R.E.M. & Scott Litt

That’s great, it starts with an earthquake
Birds and snakes, an aeroplane
Lenny Bruce is not afraid
Eye of a hurricane, listen to yourself churn
World serves its own needs, don’t misserve your own needs
Speed it up a notch, speed, grunt, no, strength
The ladder starts to clatter with fear of height, down, height
Wire in a fire, representing seven games
And a government for hire and a combat site
Left of west and coming in a hurry
With the Furies breathing down your neck
Team by team, reporters baffled, trumped, tethered, cropped
Look at that low plane, fine, then
Uh oh, overflow, population, common group
But it’ll do, save yourself, serve yourself.
World serves its own needs, listen to your heart bleed
Tell me with the Rapture and the reverent in the right, right
You vitriolic, patriotic, slam fight, bright light
Feeling pretty psyched

[Chorus]
It’s the end of the world as we know it
(It’s the)
It’s the end of the world as we know it
(It’s the)
It’s the end of the world as we know it
And I feel fine

[Verse 2]
Six o’clock, TV hour, don’t get caught in a foreign tower
Slash and burn, return, listen to yourself churn
Lock him in uniform, book burning, blood letting
Every motive escalate, automotive incinerate
Light a candle, light a votive, step down, step down
Watch your heel crush, crush, uh-oh
This means no fear, cavalier renegade and steering clear
A tournament, a tournament, a tournament of lies
Offer me solutions, offer me alternatives, and I decline

[Chorus]
It’s the end of the world as we know it
(It’s time I had some time alone)
It’s the end of the world as we know it
(It’s time I had some time alone)
It’s the end of the world as we know it
(It’s time I had some time alone)
And I feel fine
(I feel fine)

[Chorus]
It’s the end of the world as we know it
(It’s time I had some time alone)
It’s the end of the world as we know it
(It’s time I had some time alone)
It’s the end of the world as we know it
(It’s time I had some time alone)
And I feel fine

[Verse 3]
The other night I dreamt of knives, continental drift divide Mountains sit in a line, Leonard Bernstein
Leonid Brezhnev, Lenny Bruce and Lester Bangs
Birthday party, cheesecake, jelly bean, boom!

Right? Right!

It’s the end of the world as we know it

Stinking It Up At The Sinquefield Cup

The trio of announcers at the Sinquefield Cup were effusive during every round, especially during the final round. They did the best they could to put lipstick on a pig

but in the final analysis it was still a stinking pig. The gang mentioned the high percentage of draws and GM Yasser Seirawan said something like, “We haven’t noticed because of the quality of the draws.” Forty five games were played during the tournament with only eight of them ending decisively, which is 17.7%. There were nine rounds so the average was less than one win per round.

The announcers for MLBaseball teams are called “homers” for a reason. They are paid by the ball club so it is in their interest to put lipstick on their particular pig.

I am uncertain about who pays the announcers at the Sinquefield Cup, but it is more than a little obvious they want to continue being paid. It is in their interest to put as much lipstick on the Chess pig as possible. Because of this they lack objectivity. I am not being paid by anyone so can be objective. The tournament was B-O-R-I-N-G. To their credit, the announcing team of Yaz, Maurice, and Jen did the best they could to inject some excitement into the moribund tournament. The excitement certainly did not come from the players. The pigs were in full force and there was some reeking Chess played at what I have come to consider the Stinkfield Cup.

by first needlessly allowing Magnus a protected passed pawn. Later he exacerbated an already tenuous position by jettisoning a pawn for absolutely nothing, and was deservedly ground down by the ultimate grinder.

Maxime Vachier-Lagrave managed to turn what should have been a win into a draw against Sergey Karjakin because he did not know how to play the endgame.

Wesley So and Fabiano Caruana played what was arguably the most boring game of the tournament in the last round and, guess what, it ended in a draw. Watching lipstick being put on a pig was better than watching the “game.” Here is what two Chess fans posted on the ChessBomb chat at the game:

Abraxas79: So will drop out of sight soon. Will be playing open tournaments with Kamsky
eddiemac: was being interviewed and said he be in a chess960 tourney in a few weeks. Should be more exciting than this dreary tourney.
(https://www.chessbomb.com/arena/2018-sinquefield-cup/09-So_Wesley-Caruana_Fabiano)

The 71st Russian Chess Championship began less than a week ago with twelve players competing. After four rounds twenty four games have been played and seven of them have ended decisively. That is 29%. Not great, but much better than the paltry 18% of the Stinkfield Cup. At least there has been a decisive game in each of the four rounds of the Russian Championship. In the third round three games were decisive. Three of the rounds of the Stinkfield Cup finished without any decisive games.

Yaz can talk all he wants about “…the quality of the draws,” but the fact remains the games ended in yet another draw. There is not enough lipstick Yaz can smear to obviate the fact that pigs were stinking it up at the Sinquefield Cup. Chess fans want winners. Potential Chess fans do not understand the proliferation of draws; they want to see a WINNER.

The last round game causing much excitement was the game between Levon Aronian and Alexander Grischuk. Levon unsoundly sacrificed a rook on f7 and the game was all for Grischuk’s taking, but he had previously spent almost three quarters of an hour on one move which left him short of time. Still, I cannot imagine Bobby Fischer losing the game with the black pieces after 18 Rxf7 no matter how little time he had left. Give Bobby two or three minutes, maybe only one, and he would have won the game. Seriously, give Bobby only the thirty seconds added and he would have won that game!

“The Herceg Novi blitz event was the speed tournament of the 20th century. It had four world champions competing, and Bobby not only finished 4½ points ahead of Tal in second place, he also obliterated the Soviet contingent, 8½-1½, whitewashing Tal, Tigran Petrosian and Vasily Smyslov, six-zip; breaking even with Viktor Korchnoi; and defeating David Bronstein with a win and draw.” (http://www.thechessdrum.net/blog/2012/03/16/bobbys-blitz-chess/)

This was with a time limit of only FIVE minutes for the whole game! When I hear people talking about how strong are today’s Grandmasters and how the players of the 20th century would not stand a chance against the current top players I laugh. In his prime Bobby would have OBLITERATED these posers no matter the time control. Bobby played each and every game to WIN.

Because I played the Bird opening often, but not as many as the Atlanta player who became a NM using it exclusively, Adam Cavaney, who became an attorney and moved to New Orleans before hurricane Katrina, I paid close attention to the following game.

Let us review the aforementioned game between Alexander Grischuk and Wesley So from the penultimate round:

Alexander Grischuk vs Wesley So

Sinquefield Cup 2018 round 08

1. f4 Nf6 2. Nf3 b6 3. b3 Bb7 4. e3 g6 5. Bb2 Bg7 6. g3 O-O 7. Bg2 c5 8. c4 d5 9. O-O Nc6 10. Qe2 Rc8 11. d3 d4 12. exd4 Nxd4 13. Nxd4 Bxg2 14. Kxg2 cxd4 15. Na3 Nd7 16.

An analogous position after 7…c5 was reached by a different move order in this game:

David Bronstein (2585)

v Vladimir Tukmakov (2560)

Event: URS-ch40
Site: Baku Date: 11/23/1972
Round: 6
ECO: A01 Nimzovich-Larsen attack, symmetrical variation

1. b3 b6 2. Bb2 Bb7 3. e3 Nf6 4. f4 g6 5. Nf3 Bg7 6. g3 O-O 7. Bg2 c5 8. O-O Nc6 9. a4 d6 10. Na3 a6 11. Qe2 Rb8 12. d3 Ba8 13. c4 e6 14. Rfd1 Qe7 15. e4 Nd7 16. Bxg7 Kxg7 17. Nc2 e5 1/2-1/2
(https://www.365chess.com/game.php?back=1&gid=2419289&m=15)

After 13 moves this position appeared on the board:

I was certain Grischuk would play 14 Qxg2. He took with the King. In the old BC (before computer) days if one disagreed with a move a GM played we would defer to the GMs move because, well, you know, he was a Grandmaster. Still, with my limited understanding of the Royal game, my thinking was that now that the white squared bishop has left the board, what better piece to take it’s place than the Queen? Stockfish agrees.

This position was reached after 16 moves:

While Grischuk was thinking I thought he would first play 17 Ne1 followed by 18 Nf3, considerably improving the position of the woeful knight. After the game the Stockfish program at the ChessBomb made me feel like I knew something about how to play the Bird as it gives this variation as equal: 17. Ne1 e6 18. Nf3 Qd7 19. Kg1 Rfd8 20. Ba3 Qb7 21. Rae1 Bf8 22. Bb2 Bg7 23. Ba3. The clanking digital monster also shows 17 Ba3 as equal. The move Grishuk played, 17 f5, is not shown as one of the top four moves. His choice gives the advantage to black.

This position was reached after 22 moves:

SF shows 23. Qxe7 Qc6+ as best, but Grischuk played 23 gxf5. It is easy to see black has an increased advantage. After a few more moves were played we reach this position after white played 25 Qf3:

Wesley So could have simply dropped his queen back to e7 with a by now large advantage. IM Boris Kogan said, “Chess is simple. He attack, you defend. You attack, he defend. My retort was, “Maybe for you, Boris.” Wesley played 25…Qg5+, which still left him with an advantage. I was thinking, “Patzer sees a check and gives a check.”

We move along until his position was reached after 28 Qd5:

The two best moves according to SF are 28…Qf4 and/or Qb6. So played the fourth best move, 28…Qd2.

After 29…Qxa2 we come to this position:

30 Nc6 is the best move. Grischuk played the second best move, 30 Qe4.

Bobby Fischer

spoke of “critical positions.” This is one of them.

Wesley had far more time than his opponent at this point. I was therefore shocked when he took very little time to play 30…Qb2. I will admit the moved played was my first choice, but then I am not a GM. Faced with the same position Wesley So had on the board I would have probably played 30…Qb2. I followed the games at Mark Crowther’s wonderful site, The Week in Chess (http://theweekinchess.com/), because it has no engine analysis. After the game was concluded I went to the ChessBomb to see StockFish had given the move 30…Qf2 as much superior to the move played in the game. Initially flummoxed, I wondered if Wesley had taken more time, which would have meant more time for me to cogitate, would I have seen the much better 30…Qf2? Honesty compels me to think not, as 30…Qb2 attacks the knight and makes way for the passed a-pawn. What’s not to like? SF only gives 30…Qf2 followed by 31 Nc6, so I had to “dig deep” to understand the efficacy of moving the queen to f2. Fortunately for this old grasshopper there was understanding. Later I watched some of the coverage by Yaz, Maurice, and Jen. Maurice showed the engine they were using gave it as best. This begs the question, which engine were they using? I have yet to hear a name used for the “engine.” There are many “engines,” so why do they not inform we Chess fans which “engine” they utilize?

After 30…Qb2 Grischuk played 31 Nf5 (SF says Nf3 is a little better) and this position was reached:

I was thinking Wesley would play 31…Bf6, later learning SF shows it best. As a matter of fact, it is the only move to retain an advantage. Wesley So played the second choice of SF, 31…Be5, and the game sputtered to a draw, a fitting conclusion to a poorly played game by both players. So much for Yasser’s comment about “…quality of the draws.”

This is what Chess fans who chat at the ChessBomb thought about the ending of the game:

CunningPlan: I suspect draw agreed
dondiegodelavega: WTF???
BadHabitMarco: this cant have happened
rfa: yup draw
poppy_dove: BUG
dondiegodelavega: moving to twitter
CunningPlan: Maybe So missed Kxg1
jim: mdr
jim: Qxg1 wow
Frank200: hahahaha somebody was trolling
LarsBrobakken: no takebacks!
CunningPlan: So is a dirty rotten cheat
CunningPlan: Oh So. What a cop out.
rfa: 🙂
BadHabitMarco: devine intervention
Vladacval: phhhooogh
BadHabitMarco: divine
Vladacval: nice save!
jim: So touched accidentally the rook
poppy_dove: draw
dondiegodelavega: what a pussy!
CunningPlan: Grischuk deliberately dropped an eyelash on it to tempt So to brush it off
CunningPlan: Oldest trick in the book
CunningPlan: I’ve won many a game that way
BadHabitMarco: he was like “did you see that the felt was missing under my rook?”

The King and Queen Save the Day

Two more books have been published, The Queen Saves the Day: A World Champion’s Favorite Studies,

and The King Saves the Day: A World Champion’s Favorite Studies,

by Elk & Ruby. Having previously written a review (https://xpertchesslessons.wordpress.com/?s=one+pawn+saves+the+day) of the previously published books, I racked my addled brain in hopes of fostering an idea of what to add to what has already been written. After writing the earlier review the 2018/1 issue of the best Chess magazine being published, New In Chess,

arrived, which contains a review by GM Matthew Sadler

of the first two books published, One Pawn Saves the Day and One Knight Saves the Day. After reading the excellent review I sent an email to the publisher, Ilan Rubin, in which I wondered if it would be possible to publish GM Sadler’s full review on this blog, or would it infringe upon copyright law. Ilan suggested I write to the NIC folks, asking permission. Rather than do so I decided to publish an excerpt from GM Sadler’s review, which is allowed under copyright law. I also mentioned Matthew’s review was so good compared to my review that it was about as much better as the difference in our ratings. I am no Grandmaster Chess player; far from it, and I am not a GM writer, although I work hard in an attempt to be the best I can be. I strongly urge anyone reading this to obtain a copy of the magazine, or at least a copy of his review in NIC. From GM Matthew Sadler’s review, Be Prepared: The eternal question remains: how do I get myself in good shape before a tournament?

“The most fundamental requirement to playing a good tournament is to spot simple tactics. Continually missing easy tricks is terribly bad for your morale. The higher level you play, the more you need to concentrate on the difficult things – drawing up a plan, keeping up the purpose and drive in your play throughout a whole game. You need to assume that your sense of danger will pick up on the simple stuff: if you can’t, you’ll waste masses of time frantically checking and rechecking everything. Solving tactical puzzles is the obvious way, but it’s hard to find the right material. Ideally you would challenge yourself with spectacular positions ( which keep you interested) at a moderate level of difficulty (you want to give yourself a morale boost before and during the tournament, not destroy yourself!)

This time, I was extremely lucky to be able to turn to One Pawn Saves the Day and One Knight Saves the Day by Sergei Tkachenko, published by the new Elk and Ruby publishing house. These small-format books each contain 100 studies in which the hero is the piece in the title. The idea is very nice; in each of the studies, a pawn or knight will deliver the coup de grace in the final position. The author is a member of the very strong Ukrainian team which has scored consistently high placings in the World Chess Composition Tournaments (winning in 1997). Solving studies as training before a tournament was a recommendation of Mark Dvoretsky’s, but one that always filled me with trepidation. Everyone knows the feeling of staring at a fiendish study for 15 minutes and not finding any idea at all. Not the feeling I want before a tournament! These books are excellent in three ways. Firstly, the chosen studies are exceptionally beautiful. I was constantly oohing and aahing with satisfaction! Secondly, the examples are a good mix of the famous and the unfamiliar. I’ve solved a fair number of studies in the past, but about 75% of the studies in each book were unfamiliar to me, which is excellent. Thirdly, the level of the studies is very rewarding. Some are harder than others, but the knowledge that a pawn (in the first book)or a knight (in the second book) will deliver the final blow is a wonderful hint that always helps you in the right direction without revealing too much. I worked through all 200 before and during the tournament and I felt that it had helped immensely. Can’t wait until the next pieces!”

Sadler “…worked through all 200 before and during the tournament.” Imagine that, solving studies while playing in a tournament. Maybe that is part of the reason Matthew is a Grandmaster…Every day I go to Mark Crowther’s This Week In Chess (http://theweekinchess.com/), spending time attempting to solve the puzzle of the day before attempting to solve only one position from one of the two new Elk & Ruby books received recently as an attempt to keep my aged brain working. Use it or lose it! I read Sadler’s book, Chess for Life,

which deservedly won the ECF Book of the Year 2016 prize., and will recommend it wholeheartedly!

I never read any review of a book before reviewing it, unless I have read it before knowing I will review the book, because I want to keep an open mind, and think for myself. After writing the above I went to Amazon where I was surprised to find one review, by Paul Maginley, a rated Expert, as shown at the USCF website, already published for the book, The King Saves the Day: A World Champion’s Favorite Studies by Sergei Tkachenko, posted May 11, 2018. (https://www.amazon.com/King-Saves-Day-Champions-Favorite/dp/5604071013/ref=sr_1_1?s=books&ie=UTF8&qid=1528563249&sr=1-1&keywords=tkachenko)

“I retired from tournament play years ago, yet I still purchase chess books. How does one explain that? Chess remains an excellent avenue for mind exercise even if one has eschewed the rigors of competitive play. And what better way to exercise the mind than to work on endgame studies? Publisher Elk and Ruby have put out six related books on endgame studies favored by the Soviet composer Sergei Tkachenko.
The books are pocket sized and nicely produced with one puzzle per page and the solution printed on the next page thereby facilitating those who would prefer not to accidentally view the answer before attempting to solve the puzzles. There is a series of six books representing a 100 puzzles per book. The compositions represent multiple composers and one ends up with a lone king, queen, bishop, knight, rook, or pawn at the end of each puzzle. The books are pocket sized and the typeset and diagrams are large enough to rule out any eyestrain. The puzzles can be quite challenging, but the solutions frequently display a high degree of beauty and pleasure. English translations of Russian chess books are often stiff and unappealing but translator Ilan Rubin presents the material clearly and concisely.
We live in a culture dominated by the cell phone and people can be seen with their faces glued to their mobile devices whenever they find themselves in a situation involving any kind of waiting. What better way to overcome such dead time than to pull out one of these books and work out a beautiful endgame composition? The books are affordably priced at $11.99 each. I don’t know how many will ultimately be printed, but it would make sense to jump on these while they last.
If poetry represents the ultimate beauty of literature then I can argue that endgame studies represent the ultimate beauty of chess. If I were to find myself exiled on a small island and allowed only a handful of chess books, most of them would likely be books on endgame studies. These wonderfully diminutive volumes would be worthwhile selections for any kind of trip. I look forward to seeing more from this small publisher.”

I cannot add anything to that wonderful review, other than to say “Ditto!” This series of books will bring pleasure and enjoyment while sharpening your tactical awareness.

Games Have Been Terminated!

The thing about writing a blog is that one never knows what an email will bring. After spending an inordinate amount of time in front of Toby, the ‘puter, yesterday learning how to insert diagrams, and then putting together the post in order to have something in which to insert them, I determined that today I would spend time with the Daniel Gormally book, Insanity, passion and addiction: a year inside the chess world, while playing over Chess games on an actual board with pieces one can feel, and possibly “working” on the openings intended for the Senior Championship of the Great State of South Carolina, which is only ten days away, by going to the CBDB and 365Chess. Wrong, Ke-mo sah-bee! An email from my friend Mulfish arrived at 11:42 am, upsetting the Bacon cart…

“Looking forward to the AWs take on AlphaZeros stunning win over Stockfish,” was the message. “What’s this?” I thought, wondering if Mike was referring to the TCEC Computer Chess Championship that is in the final stretch. “But Stockfish is not participating in the Super Final,” I thought. I therefore fired off an immediate response: “To what, exactly, are you referring?” His reply was, “Look in the all things Chess forum.”

Although there are not as many incoming as there were before taking a long break from blogging, I have received several emails directing my attention here and there, and they are greatly appreciated. Checking the AW stats today showed many people in countries other than the USA reading the AW. In particular I noticed that today, as every day, there is one, and only one, reader in the Maldives. Thank you, whoever you are, and feel free to send an email, as I am curious by nature.

Keep ’em coming: xpertchesslessons@yahoo.com

This is the post found on the USCF forum that prompted Mulfish to fire a salvo at the AW:

Postby billbrock on Wed Dec 06, 2017 9:16 am #321974

“AlphaZero learned to play chess by playing against itself. After just FOUR HOURS of self-learning, it was able to decisely (sic) defeat Stockfish 8.0! (EDIT: this statement is slightly misleading. See downthread.) (100 games match: +28 =72 -0)
What’s really impressive: Stockfish was calculating far more deeply than AlphaZero (at least in terms of nodes per second). AlphaZero is just “smarter.”

After reading only this I thought, “Whoa! This will change not only my day, but possibly the future course of history!” The more I read the more convinced was I of the latter.

Bill Brock provided a link to a PDF paper, Mastering Chess and Shogi by Self-Play with a General Reinforcement Learning Algorithm
(https://arxiv.org/pdf/1712.01815.pdf) which I read immediately, blowing my mind…

Every morning I read while drinking my first cuppa coffee, and today was no exception. Toby is not fired-up until time to sit down and eat breakfast. I check my email, then the quotes of the day, followed by the poem of the day, which was The Writer’s Almanac, by Garrison Keillor, but it has been discontinued, so I’ve moved on to Poem-a-Day (https://www.poets.org/poetsorg/poem-day) & The Poetry Foundation’s Poem of the Day (https://www.poetryfoundation.org/). Next I click on the Drudge Report in order to understand what the enemy is thinking, and doing. Then it is the newspapers in digital form, the NYT, WaPo, and AJC. For you readers outside the USA, that would be the New York Times, the Washinton Post, and the Atlanta Journal & Constitution. Then I check out the word of the day (https://www.merriam-webster.com/word-of-the-day), before heading to check what was on the nightly radio programs broadcast while I am sleeping, Ground Zero with Clyde Lewis (http://www.groundzeromedia.org/), and the Granddaddy of them all, Coast to Coast AM (https://www.coasttocoastam.com/). You may think that Chess comes next, but you would be mistaken. I check out The Hardball Times at Fangraphs (https://www.fangraphs.com/tht/). Then I check out what’s happening in the world of Go (http://www.usgo.org/).

Then it is time for Chess! My routine is to check in at Chess24 (https://chess24.com/en) first in order to learn if there is a new article I will want to return to after checking out Chessbase (https://en.chessbase.com/), where there is usually something interesting to peruse. (Today is no exception because the lead article is, How XiangQi can improve your chess, which will be read. https://en.chessbase.com/). During the TCEC Championships it is then on to Chessdom (http://www.chessdom.com/), where I click onto TCEC (http://tcec.chessdom.com/). And then it is on to the Chess Granddaddy of them all website, TWIC, aka The Week In Chess (http://theweekinchess.com/), which is Mark Crowther’s wonderful website which contains a Daily Chess Puzzle, which I attempt to solve, in hopes it will keep my mind sharp. Why was I writing all this?…Just kidding!

The point is that I read so long this morning (Why Bob Dylan Matters, by Richard F. Thomas; Cover Me: The stories behind the GREATEST COVER SONGS of all time, by Ray Padgett, who has a wonderful website (http://www.covermesongs.com/); and Murder on the Death Star: The assassination of Kennedy and its relevance to the Trump era, by Pelle Neroth) in order to finish the latter. The point being that by the time I got to the email by Mulfish I would ordinarily have already seen the momentous news.

DeepMind’s AlphaZero crushes chess

https://chess24.com/en/read/news/deepmind-s-alphazero-crushes-chess

The excellent article by Colin McGourty begins: “20 years after DeepBlue defeated Garry Kasparov in a match, chess players have awoken to a new revolution. The AlphaZero algorithm developed by Google and DeepMind took just four hours of playing against itself to synthesise the chess knowledge of one and a half millennium and reach a level where it not only surpassed humans but crushed the reigning World Computer Champion Stockfish 28 wins to 0 in a 100-game match. All the brilliant stratagems and refinements that human programmers used to build chess engines have been outdone, and like Go players we can only marvel at a wholly new approach to the game.”

Colin ends with: “And where do traditional chess programmers go from here? Will they have to give up the refinements of human-tuned evaluation functions and all the existing techniques, or will the neural networks still require processing power and equipment not easily available? Will they be able to follow in DeepMind’s footsteps, or are there proprietary techniques involved that can’t easily be mastered?

There’s a lot to ponder, but for now the chess world has been shaken!”

“Shaken?” More like ROCKED TO ITS FOUNDATION!

If games people play are to survive they will be something like that described in the novel I consider the best I have read, Das Glasperlenspiel, or Magister Ludi, aka, The Glass Bead Game, by Hermann Hesse. (http://www.glassbeadgame.com/)

Or maybe a book, The Player of Games, by Iain M. Banks, which is not only one of my favorite Sci-Fi books, but also one of my favorite book about games.

The stunning news also caused me to reflect on a Canadian Sci-Fi television program I watched, Continuum, in which mega-corporations dominate the world in the future as time-travelers fight one of the largest corporatocratic entities, SadTech, which sounds an awful lot like Google. (http://www.imdb.com/title/tt1954347/?ref_=nm_flmg_act_6)

The Brave New World is here. The Science Fiction books I read as a youngster are no longer fiction.

The Terminator has arrived.

We are all doomed. DOOMED!

R.E.M. – It’s The End Of The World

The End of the World

The Dragon vs The Magician

The TCEC Season 10 – Superfinal between defending Champion Komodo and challenger Houdini has begun! As I write game five has just ended and game six began immediately. Games are played 24/7 until all ONE HUNDRED games are finished. I wonder what La Bourdonnais and McDonnell, who played a series of six matches, a total of eighty-five games, between June and October 1834, would have to say about the Superfinal?

Before calling it an evening about ten o’clock last night it looked as though the Dragon would score first with the Black pieces in a MacCutcheon variation of the French defense. TCEC narrows it down further to, “Lasker, 7.bxc3.” Imagine my surprise to learn this morning that it was not the Dragon taking the lead, but the escape artist known as Houdini the Magician! Houdini managed to draw the game, with much help from Komodo, and then draw first blood by beating the Dragon’s “Sicilian: Taimanov, 6.Be3 a6 7.Qd2.”

I have been following the TCEC computer program championships for years. I still enjoy watching the games played by humans, but let’s face it, if it were Baseball the only way to describe it would be akin to watching minor league baseball as opposed to Major League Baseball. The difference in the lay is so great now that humans could be described as playing at least two levels lower than computer programs, something along the line of the difference between MLB and class AA baseball, maybe even class A. Do not get me wrong, I have watched, and enjoyed, many a minor league baseball game, and, for that matter, many college baseball games, in many different cities, but if I want to watch the best baseball being played, I must go to a MLB game. That is one reason I have found it so humorous that the F.I.P.s at FIDE have decided to try and bilk the small Chess public out of all they can by charging to watch the games played during real time. Back in my day we waited until the next day for the games of the World Championship to appear in a newspaper, and WE LIKED IT! Now the fools in power charge for what one can obtain just a few hours later on the internet after the completion of the games. As far as Chess moves go this one is what GM Yasser Seriwan would call a “Howler.” The only thing FIDE has done is hurt people like Mark Crowther, who has put out The Week In Chess for decades. (http://theweekinchess.com/) I mention TWIC because Mark shows only a Chess board and the moves, without any kind of analysis whatsoever, for those of us who prefer to actually THINK about what move may come next. These FIDE people are so stupid they do not even realize they are damaging the game because the GAMES are PUBLICITY, which bring more PEOPLE into CHESS. If it were not so serious I would LAUGH. As it is, it makes one want to CRY. What FIDE is doing is reminiscent of greedy MLB owners refusing to allow radio, and then television, broadcasts thinking it would cut down on attendance, until one owner thought it could possibly be good for the game by bringing the game to the fans, thereby engendering more fans.

The Superfinal is the third stage of the Championships. I was transfixed by the first stage this season, the tenth, as what many would call “offbeat” openings were used. This was right up my alley! When playing over the board I built an opening repertoire (http://www.mark-weeks.com/aboutcom/aa02i07.htm) consisting of hand written openings kept in what one legendary player called “Bacon’s book of death lines!” Before lost in what I now call the “Crazy Cousin Linda Flood,” the BODL was intact except for the cover, which had been lost somewhere on the Chess road who knows when. Now whole books are written devoted to what were my “death lines,” such as, The Extreme Caro-Kann: Attacking Black with 3.f3, by Alexey Bezgodov. I hope to live long enough to see a book on 2 Qe2 versus the French.

The expected media follows after a data dump. Here are the games I copied from the first stage, hoping to find time to look at each and every one of them. This should give those of you asking “Who are you?” insight to my Chess character.
