1. g1f3  1... d7d5  2. d2d4  2... g8f6  3. c2c4  3... e7e6  4. b1c3  4... f8b4 The Ragozin Defense has taken the place of the Queen's Indian as the top repertoire choice for anyone looking for a variation to match the Nimzo-Indian. 5. c4d5  5... e6d5  6. c1f4 One of White's many options against the Ragozin. 6... f6e4  7. a1c1  7... b8c6  8. g2g3 A rare move, with only a few games in the database. 8... c8f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] The most accurate reply, threatening to win the exchange. 9. d1a4  9... d8e7 A difficult decision as this allows White's knight to go to e5. 10. f3e5  10... e8g8  11. e5c6  11... b7c6  12. f1g2  12... e4c3  13. b2c3  13... b4a3  14. c1d1  14... a3d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] 15. f4d6  15... e7d6  16. e1g1 At first sight, it seems White should be better with a more compact pawn structure, but this is compensated by Black's control of the b-file. The bishop on f5 plays a very important role, taking the b1-square away from White's rook. 16... f8b8  17. d1d2  17... b8b6 [%c_effect b6;square;b6;type;GreatFind;persistent;true] Black prepares to double rooks on the important open file. 18. f1c1  18... a7a5  19. h2h4 [%c_effect h4;square;h4;type;Inaccuracy;persistent;true] At this point it's impossible to foresee how important the h-file is going to be in this game, but considering what will happen maybe White should play the pawn to h3 and not to h4. For instance: 19... h7h6  20. e2e3  20... g7g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] A very nice move, opening the h-file and gaining a clear plan of action. 21. h4g5  21... h6g5 White cannot wait any more, as Black is ready to play Rg7-Rh8-Qh6 and start an attack on the h-file. 22. a4d1 [%c_effect d1;square;d1;type;Inaccuracy;persistent;true] 22... d6a3  23. c3c4  23... a8b8 [%c_effect b8;square;b8;type;GreatFind;persistent;true] The rook is ready to go to b1. 24. g1h2  24... g5g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] Restraining the white queen. 25. d1f1  25... b6b1  26. d2d1  26... b1c1  27. d1c1  27... b8b2 [%c_effect b2;square;b2;type;GreatFind;persistent;true] Even better than 27...Qxa2. 28. c4d5  28... c6d5  29. f1e1 [%c_effect e1;square;e1;type;Inaccuracy;persistent;true] 29... a3a2  30. c1a1  30... a2c4  31. a1a5 [%c_effect a5;square;a5;type;Inaccuracy;persistent;true] This loses in elegant fashion. 31... b2b1
