1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. c2c3  3... g8f6  4. f1d3 This is not the most popular of the Anti-Sicilians, but it still has close to 5,000 games in my database. White's idea is simple: the bishop goes back to c2 and then the d-pawn will be advanced one or two squares. The problem with this variation is that Black manages to develop the pieces without any problems, so it's not difficult to equalize. 4... b8c6  5. d3c2  5... c8g4  6. d2d3  6... e7e6  7. b1d2  7... d8c7  8. h2h3  8... g4h5  9. d1e2  9... f8e7  10. d2f1  10... e8c8 [%c_effect c8;square;c8;type;Interesting;persistent;true] A bold move. 10...d5 or 10...0-0 is safer. 11. f1g3  11... h5g6  12. e1g1  12... d6d5 We have a double-edged position on the board. Positions with kings on opposite sides are always tense. 13. f3h4 This is not an easy move. Nakamura prepares to capture the bishop on g6, even though this opens up the h-file. Another option is to release the central tension, but Black has no problems after 13... c8b8  14. h4g6  14... h7g6  15. c2a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true] A nice move, activating the bishop. 15... d5d4 [%c_effect d4;square;d4;type;Inaccuracy;persistent;true] The wrong way to define the situation in the center. 16. c3c4  16... f6d7  17. f2f4  17... b8a8  18. e4e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] White has time to prepare the activation of the knight via e4. 18... d7b6  19. a4d1 [%c_effect d1;square;d1;type;Inaccuracy;persistent;true] 19... g6g5 [%c_effect g5;square;g5;type;Inaccuracy;persistent;true] Shankland correctly judges that it's necessary to advance the pawns on the kingside, but the execution of the plan is not the best. 20. f4g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] 20... c6e5  21. c1f4  21... e7d6  22. g3e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] 22... e5c4 The only move; of course, Nakamura had seen this. 23. e4d6  23... c4d6  24. d1b3  24... b6d5 [%c_effect d5;square;d5;type;Mistake;persistent;true] After this move White has a nearly winning advantage. 25. b3d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 25... e6d5  26. e2e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] Either the d5 pawn or the g7 pawn will fall. 26... c7c6  27. e5g7  27... d6f5  28. g7f7  28... h8f8  29. f7c7  29... c6b5  30. f4d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] Simplifying the position. Now the passed pawns on the kingside will be fatal. 30... f5d6  31. f1f8  31... d8f8  32. c7d6  32... f8e8  33. a1f1
