1. c2c4  1... e7e6  2. b1c3  2... d7d5  3. d2d4  3... f8b4 An interesting order of moves, usually taking the game to a position usually arising from the Nimzo-Indian or the Ragozin Defense. 4. a2a3 A popular system, White doesn't mind the exchange of the bishop for the knight on c3 and even provokes it. 4... b4c3  5. b2c3  5... g8f6  6. e2e3  6... e8g8 Considering the position we will see in the game, which I find very difficult to play as Black, it's worth trying the more subtle 7. c4d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 7... e6d5  8. f1d3 White's plan is very simple: to play Ne2, 0-0, f3, and e4, and then begin an attack on the kingside. The absence of the dark-squared bishop in the defense makes the attack even more dangerous. Since the classic Botvinnik-Capablanca game from the 1938 AVRO Tournament, the dangers of this pawn structure have been well-known. 8... c7c5  9. g1e2  9... b7b6  10. e1g1  10... c8a6 Exchanging the light-squared bishop is useful to the defense, and this has always been the most popular plan. 11. f2f3  11... f8e8  12. e2g3  12... a6d3  13. d1d3  13... b8c6  14. c1b2 An important theoretical position, played in hundreds of games. Black is in a dangerous situation, and I definitely prefer playing something else before, as here you need to know the moves precisely and a small mistake will be fatal. 14... d8d7 [%c_effect d7;square;d7;type;Mistake;persistent;true] This is already a losing move. 15. e3e4 The realization of White's strategy. If Black does nothing, then e4-d5 is crushing. 15... d5e4  16. f3e4  16... c6e5  17. d3e2  17... e5g6  18. f1f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true][%cal lf1f6][%c_arrow f1f6;keyPressed;ctrl;from;f1;opacity;0.8;to;f6;persistent;false][%c_highlight f6;keyPressed;none;opacity;0.8;square;f6;persistent;false] A thematic exchange sac that is irresistible and good. 18... g7f6  19. g3h5  19... e8e6  20. d4d5  20... e6d6  21. c3c4 With the opening of the bishop's diagonal, White can now quickly prepare a decisive attack. The position is completely winning. 21... g6e5  22. h2h3 Only this is a novelty. 22... d7e7  23. a1f1  23... a8e8  24. h5g3 [%c_effect g3;square;g3;type;GreatFind;persistent;true] The knight isn't bad on h5, but it will be even better on f5. 24... e7f8  25. g3f5  25... g8h8  26. e2h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] Krush chooses the best of many tempting options. 26... b6b5 A desperate attempt to complicate the game. Black's problem is that the e5-knight can never move from its position, as this would open the way for the bishop. 27. f5h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] Preparing to capture on e5 and then on f7, among other ideas. 27... h8g7  28. c4b5 White takes the time to simply capture the pawn on b5 before continuing the attack. Why not $2 28... c5c4  29. h6g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true]
