1. e2e4  1... c7c5  2. b1c3  2... b8c6  3. f1b5 A popular subvariation for those who don't like opening the game against the Sicilian. 3... c6d4  4. b5c4  4... e7e6  5. g1e2  5... a7a6  6. a2a4  6... g8f6  7. e1g1  7... d7d5  8. e4d5  8... e6d5 It's clear that Black has absolutely no problems in this position. 9. c4a2  9... d4e2  10. d1e2  10... f8e7  11. d2d3  11... e8g8 [%c_effect g8;square;g8;type;Inaccuracy;persistent;true] This allows White to win a pawn. 12. c3d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 12... f6d5  13. a2d5  13... d8d5  14. e2e7 Black is close to equality thanks to his activity and the opposite-colored bishops. But I'd rather have equality being a pawn up than a pawn down. 14... c8e6  15. e7g5  15... d5g5 Only now does the game take a unique character. 16. c1g5  16... f7f6  17. g5e3  17... c5c4  18. d3c4  18... e6c4  19. f1e1 The endgame has a great tendency for a draw, but White can press without any risk. That's a pleasant feeling for a chess player—you know you're going to have your opponent defending for hours, and the worst that can happen is to get a draw. 19... b7b5  20. a4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] When you have a material advantage in an endgame, keep the pawns on the board. This is a classic rule that has multiple exceptions, but it's still good to know. 20... f8e8  21. a1d1  21... a8d8
