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
