2017 3 Tables - June (82) Round 2
Anton Taylor, 2024 - Justin Storn, 2084
French: KIA (C00)

1. e4 e6 2. d3 d5 3. Nd2 Nf6 4. Ngf3 c5 5. c3 Nc6 6. Be2 b6 7. O-O Bb7 8. Re1 Be7 9. Qc2 Qc7 10. Nf1 O-O-O This is the first non-book type of move but isn't inconsistant with black's other moves. Even with the imbalances the position is roughly equal. Black is just a little bit better by the computer's evaluation but in practice it's probably equal. 11. Bg5 h6 12. Bh4 Nh5 13. Bxe7 Qxe7 14. a4? A useless "equal" move that appears to accelerate the attack but controlling the center after exd5! is far better. 14. ... Nf4 15. Ng3?? exd5 again is missed and a losing move is chosen in favor of the right path. Black is poised to attack directly against white's king if white plays actively in defense. Take this line for example: 15... Kb8 16. Rad1 g5 17. Bf1 h5 18. exd5 Rxd5 19. Ne2 Ng6 20. Nc1 g4 21. Nd2 h4 22. Be2 Nce5 23. f3 Qg5 24. fxg4 Qe3+ 25. Kh1 h3 26. Nf3 hxg2+ 27. Kxg2 Nf4+ 28. Kh1 Nxf3 29. Bxf3 Qxf3+ 30. Kg1 Nh3# 15. ... g5 16. Bf1 g4 17. Nd2 h5 This version of the kingside attack is one move slower than the example line in the previous comment. As a result Black is still better but not yet winning. 18. Ne2 Qg5 Black is trying to hold on to the kingside attack because he intuitively assumed he was winning in attacking on previous moves but has chosen the wrong path. 19. Nxf4 Qxf4 20. g3?? Komodo shows this is again a losing choice. By principle moving the pawns in front of your king is a horrible idea because it accelerates the potential to open lines against your king. 20. ... Qf6 21. Bg2 h4 22. b4 Komodo absolutely hates this idea and prefers to distract black's pieces with the sacrifice a4. Black is clearly winning and so white has to drum up distraction and activity to make a bid for the point. 22. ... hxg3 23. fxg3 Qh6? Rxh2! is a great sacrifice that breaks open white's position convincingly. Kxh2? is met by Qf2 when white's king gets trapped in the corner. 24. Nf1 This move order allows white to hold himself together. 24. ... cxb4 25. cxb4 Kb8 26. b5 Na5? Nd4 keeps piling on the pressure. 27. Rac1 Rc8 28. Qd2 Qg7?? Holding onto the queen is a losing retreat. White has new life a tries his best to pounce on the opportunity. 29. exd5 Bxd5 30. Qf4+ Ka8 31. Bxd5+ exd5 32. Ne3 The immediate rook trade is better by komodo but I preferred to try and develop the knight to a better place. I was distracted by trying to win the g-pawn and hold my position together and missed the winning ideas. 32. ... Rxc1 33. Rxc1 Qh7 34. Nxg4 f5 I felt I was winning but I missed the most challenging continuation. Rc7 getting a tempo on the queen is the best option. 35. Nf2 Qxh2+ 36. Kf1 Rg8 37. Qxf5? Qe5 is an easier win. the test makes it harder. 37. Qxg3 38. Rc8+ Rxc8 39. Qxc8+ Qb8 40. Qe6? The last vestige of the white win drops away here. Black's queen checks and holding the d-pawn prevents white from pushing his win. Qd7 is the right answer and wins the extra pawn. it's a hard win practically. 40. ... Qd8 41. Ng4 Nb7 42. Ne5 d4 43. Nc6 Qh8 44. Qe4 Qh3+ 45. Ke2 Qh2+ 46. Kd1 Qg1+ 47. Kc2 Qf2+ 48. Kb1 Qf1+ 49. Ka2 Qf7+ 50. Ka3 Nc5 51. Nd8+ Nxe4 52. Nxf7 Nc5 53. Ne5 Kb7 54. Kb4 a5+ 55. bxa6+ Kxa6 1/2-1/2 I very much dislike games that feature all three results. It constitutes a major hole in my ability to calculate if I see tactical shots in my post-game analysis.
