P. Iniyan IM (2460) India

vs Mikhail Kobalia GM (2599) Russia

A89 Leningrad Dutch

Aeroflot Open 2018 Rd 8

1. d4 f5 2. c4 Nf6 3. Nf3 g6 4. g3 Bg7 5. Bg2 O-O 6. O-O d6 7. Nc3 (This is the main line of the A87 Dutch, Leningrad. Black now has a choice between three moves, Qe8, the move most often chosen by the man who wrote the book on the Leningrad, GM Vladimir Malaniuk, as it is the only move he considers in his excellent book, The Leningrad Dutch: An Active Repertoire Against 1 d4, 1 c4, 1 Nf3;

Nc6, my move; and c6, the move Stockfish considers best at the CBDB. Yet the Fish shows Nc6 best in the analysis to this game at the ChessBomb (https://www.chessbomb.com/arena/2018-aeroflot-open/08-Iniyan_P-Kobalia_Mikhail)!

Nc6 8. d5 (The main move, although Houdini at CBDB considers the seldom played Qc2 equal to d5)

Ne5 (There is disagreement about this move. The Stockfish and Houdini programs at CBDB show Ne5 best, while Komodo prefers Na5. The Stockfish program at ChessBomb has Na5 as much superior.)

9. Nxe5 dxe5 10. e4 (SF has this as first move at DaBomb, while the Dragon considers Qb3 best)

f4 (This has been the most often played move, but SF prefers the little played e6)

11. gxf4? (Although most often played the clanking digital monsters have little respect for it. The first choice of Stockfish at both the ChessBomb and CBDB is a4, a move that has yet to be played. Houdini plays b3, while Komodo plays Qe2! If you are a regular reader of this blog you know why I attach the exclam. This move is not one of the four choices given by SF in the analysis of the game at DaBomb. The other three moves are, in order, b4;b3; & Re1)

exf4 12. e5 (The ‘main’ move, but SF does not even list it! In order we have, Bxf4, by far the best according to SF; Kh1;Rb1; & f3

Ng4 13. e6 Ne5

14. Qa4? (There is total agreement that Re1 is the best move)

f3 15. Bh3

Nd3 (15…c6 16. Rd1 Qe8 17. c5 h6 18. Qe4 g5 19. Bf5 Qh5 20. h3 Kh8 21. d6 Rxf5 22. Qxf5 Bxe6 23. Qxe6 g4 24. Kf1 gxh3 25. dxe7 1-0, Tapani Sammalvuo (2375) v Sami Petteri Pitkanen [no rating given] Espoo op1 1997)

16. Qd1 Nxc1 17. Qxc1 b6 18. Ne4 Ba6 (b5!) 19. Rd1 Be5 20. Qh6 Bg7 21. Qh4 h6 22. Kh1 Bxc4 23. Rg1 Qe8

24. Rg3 ( (24. d6! cxd6 25. Nxd6 exd6 26. Qxc4) Bxd5 25. Rag1 Bxe4 26. Qxe4 g5 27. Bf5 (Bf1 with the idea of Bd3 is better) Rd8 28. Bg6 Rf4 29. Bf7+ Kh8 30. Qxf4 gxf4 31. Rxg7 Qf8 32. R7g4 c5 33. a4 a6 34. h4 b5 35. axb5 axb5 36. Kh2 c4 37. Kh3 b4 38. Rxf4 Rc8 (c3! Passed pawns must be pushed)

39. Rxf3? (This game has been a struggle. Although understandable, as the pawn on f3 has been a constant thorn in white’s side most of the game, this move is an awful mistake. By playing 39 Rgg4, putting pressure on the queen side pawns, the game would have remained in balance. This move takes the game from even to LOST.) c3 (Turn out the lights, the party’s over) 40. Rfg3 c2 41. Rc1 Qd8 42. Rg8+ Qxg8 43. Bxg8 Kxg8 44. b3 Kg7 45. Kg4 Kf6 46. Kh5 Kxe6 47. Kxh6 Ke5 48. Kg7 0-1

Roman Martynov FM 2319 (UKR) v Mikhail Kobalia GM 2599 (RUS)

European Individual Championship 2018 round 03

1. d4 f5 2. Nf3 Nf6 3. g3 g6 4. Bg2 Bg7 5. O-O O-O 6. b3 (This system was the choice of IM Boris Kogan from whom I learned much, so I have a great deal of respect for b3 versus the Leningrad.That said, there is total agreement between the Big 3 that 6 c4 is the best move. Yet in actual practice the databases show both b3 and b4 scoring higher than the ‘best’ move))

d6 (The Dragon and the Fish both prefer 6…Ne4)

7. Bb2 Ne4 (GM Vladimir Malaniuk reached this position 45 times, but never played the game move. Although the Stockfish program at Chess Bomb has Ne4 as best, the SF, and Houdini, at the CBDB show 7…e6 as the best move.)

8. c4 (Although 8 Nbd2 is played more often, the clankin’ digital monsters all agree c4 is better.)

Nc6 (8…e5 9. dxe5 Nc6 10. Qd5+ Kh8 11. Nc3 Nxc3 12. Bxc3 dxe5 13. Qc5 Re8 14. Rad1 Qe7 15. Qxe7 Rxe7 16. Rd2 Kg8 17. Rfd1 h6 18. e4 g5 19. exf5 Bxf5 20. h3 Bg6 21. Rd7 Rae8 22. Rxe7 Rxe7 23. Nd2 e4 24. Bxg7 Kxg7 25. Re1 Nb4 1/2-1/2, F. Baumbach (2495) v R Langeveld (2681) Mostert Memorial email tt 2006)

9. Nbd2 e5 10. dxe5 (The SF program at ChessBomb shows 10 d5 as best, but the SF program at the CBDB prefers taking the pawn, while Komodo would play a TN, Rc1)

Nxd2 (Although this is the most often played move, there is disagreement between the Big 3. SF takes the knight, but the Dragon and Houdini play 10…Nc5, the move the SF program at DaBomb has as best. Go figure…)

11. Qxd2 dxe5 12. Qd5+ Kh8 13. Qxd8 (By far the most often played move, but Houdini would play Qc5, as would the SF at DaBomb)

Rxd8 14. Rfd1 Re8 (SF and Houey prefer 14..e4)

15. e4 (This is a TN. The SF at DABomb prefers Rab1, which would be a TN; the SF at the CBDB plays Ng5. Houdini prefers 14 Ng5. See Szmacinska v Lazarevic below. For 14 Rd2 see Izsak v Torma below. The Fish would play 14 Rad1)

f4 16. Bc3 a5 17. Rd2 h6 18. Ne1 g5 19. Nd3 Rf8 20. a3 Kh7 21. f3 b6 22. a4 h5 23. Rf1 Be6 24. gxf4 exf4 25. Bxg7 Kxg7 26. h4 gxh4 27. Kh2 Rad8 28. Rfd1 Kh6 29. Bh3 Bg8 30. Kg2 Rd4 31. Kf2 Rd6 32.
