In the fourth round of the US Senior Chess Championship being held at the St. Louis Chess Campus International Master Igor Khmelnitsky,

with the white pieces, faced Grandmaster Joel Benjamin.
The game began:
1.d4 Nf6 2.Bf4 d6 3.Nc3 c6 4.e4 Qa5 5.Qe2

Regular readers know of my predilection for this particular move of the Queen, but that stems from the famous Chigorin move in the French defense after 1 e4 e6 2 Qe2, and not because the move putting the Queen in front of the King should be played just because it is possible. After Joel played 4…Qa5 Igor had a small advantage which was larger than if his opponent had played the choice of Stockfish, 4…Qb6. Igor’s choice of 5 Qe2 jettisoned the advantage. Why would any titled player make such a move? The SF program at Lichess.com shows the best move is 5 Bd2. Here’s the deal, after 5…e5 6.dxe5 dxe5, white plays 7 Bd2. After the following moves, 7…Na6 8.a3 Be6 9.Nf3 O-O-O 10.Nd5 Qa4 11.Nxf6 gxf6 12.b3 this position is reached:

Yasser Seirawan, Christian Chirila, and Alejandro Ramirez, were big on the exchange sacrifice after the move 12…Rxd2, which they, and the ‘engine’ liked. The question was would Joel pull the trigger?
The plan had been to use this game in the previous post in lieu of the game with Shabalov so there would be two exchange sacrifices rather than the possible sacrifice of the knight on f7, which Joel declined. That was prior to my doing the due diligence that should have been done earlier. I did not go to 365Chess.com and check out the opening because, well, you know, who in his right mind would play such a lame move as 5 Qe2 in that position? What was found rocked the AW. Not only had the move of the Queen been previously played but it had been played against non other than GM Joel Benjamin!

It was then obvious why Igor had played the move of the Queen. Joel had lost the game played years ago, so Igor, after doing his due diligence, decided to play it again while putting the question to GM Benjamin. Had Joel done his homework? One would assume GM Benjamin would have spent much time replaying and annotating the lost game because even lower rated players will scrutinize their losses, so that in the event the same position occurs on the board in a future game they will be prepared and have an answer. Obviously, this did not happen in this case, and it cost Joel dearly. This position was reached in both games after the moves 1.d4 Nf6 2.Bf4 d6 3.Nc3 c6 4.e4 Qa5 5.Qe2 e5 6.dxe5 dxe5 7.Bd2:

When seeing the position for the first time GM Benjamin played 7…Bg4. He played a different move against Igor:

After surfin’ on over to the analysis program at Lichess.com it was learned the best move in the position, according to the Stockfish program, is 7…Bc5, something Joel should have known. I have previously written about how the programs are revolutionizing the opening phase of the game and how older players who refuse to do their homework are being cut to pieces, metaphorically speaking, over the board (https://xpertchesslessons.wordpress.com/2022/06/04/ben-finegold-loses-to-alexander-shabalov-before-drawing-out-the-string/). It is not my intention to judge any player too harshly because we are still in a pandemic. The play has been erratic, if not atrociously abominable, replete with what Yasser likes to call “howler” moves being made with regularity. Still, coming to the board without being prepared is unforgivable. Older players simply MUST forget most of what they have learned about the openings they play and look at them with “new eyes.” The days of getting by with what you know, Joe, are over. It is no longer possible for older players to “wing it.” Seniors can no longer say, “I’ve had this position a million times!” It no longer matters how well one thinks he knows the opening because, as Bob Dylan sang, “Things Have Changed.”
