1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5  3... e7e5  4. e1g1  4... f8e7 [%c_effect e7;square;e7;type;Interesting;persistent;true] A rare idea in a well-known position. 5. f1e1  5... c6d4 Already a new move. A novelty on the fifth move of such a mainstream opening as the Rossolimo is an impressive accomplishment. 6. f3d4 [%c_effect d4;square;d4;type;Inaccuracy;persistent;true] This is not the best way to fight for the advantage. 6... c5d4  7. c2c3  7... g8f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] This is Black's excellent idea: to play with doubled pawns and follow up with the …d7-d5 advance. I imagine this was well-studied beforehand by Predke, since at first glance it seems positionally dangerous for Black. 8. c3d4  8... e5d4  9. d2d3  9... e8g8  10. b1d2  10... d7d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 11. e4e5  11... f6d7  12. d2f3  12... d8b6 The black pieces have good potential and the bishop on b5 is in an uncomfortable situation, all of which compensates for the doubled pawns. Black can even sacrifice one of these pawns, as we will see. 13. b5a4  13... d7c5  14. a4c2 The white bishop is horrible on this square, but he will still have his redemption in this game. 14... c8g4  15. h2h3  15... g4h5  16. g2g4 White can´t live with the pin on the f3-knight. 16... h5g6  17. f3d4  17... c5e6 [%c_effect e6;square;e6;type;GreatFind;persistent;true] This move is the justification for the pawn sacrifice. 18. d4f3 [%c_effect f3;square;f3;type;Inaccuracy;persistent;true] White's position starts to become dangerous after this move. 18... a8c8 Black has two tempting alternatives. 19. c2b3  19... b6b5 This is an inaccuracy. Black has several interesting alternatives, all of which offers compensation for the pawn. 20. d3d4  20... e7b4 I'm also not a big fan of this move. 21. e1e3  21... e6f4 [%c_effect f4;square;f4;type;Mistake;persistent;true] 22. c1d2 [%c_effect d2;square;d2;type;Inaccuracy;persistent;true] This is enough for an advantage, but not the best. 22... f4h3  23. g1g2  23... h3f4  24. g2g3  24... f4e6  25. a2a4  25... b5a5  26. d2b4  26... a5b4  27. b3d5  27... c8c2 [%c_effect c2;square;c2;type;Inaccuracy;persistent;true] This move allows White to stabilize the bishop. 28. b2b3  28... f8d8  29. d5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] 29... e6d4 A tactical attempt to recover material, but it doesn't work. 30. f3d4  30... c2d2  31. d1e1  31... d8d4  32. e5e6 This natural move is practically irresistible, but one thing I learned from analyzing with the computer is not to underestimate the power of candidate moves. 32... b4d6
