1. d2d4  1... d7d5  2. c2c4  2... e7e6  3. g1f3  3... a7a6 This cunning little move threatens to capture on c4 followed by the protection of the pawn with ...b7-b5. White usually captures on d5, which in some ways is desirable for Black since the light-squared bishop can be developed. The big question is whether it's worth \"wasting\" a tempo with ...a6 for this, although even this move is useful in a number of situations. 4. c4d5  4... e6d5  5. b1c3  5... h7h6 [%c_effect h6;square;h6;type;Interesting;persistent;true] Another subtle pawn move with the idea of preventing the development of White's bishops. Super-GMs are above the common laws of opening play. Carlsen has played this system a few times already. 6. c1f4  6... g8f6  7. e2e3  7... f8d6  8. f4e5 [%c_effect e5;square;e5;type;Interesting;persistent;true] An interesting idea: instead of exchanging bishops, White places it on e5 and waits for Black to capture it in order to place the knight or a pawn on that square. 8... c7c6  9. f1d3  9... e8g8  10. h2h3  10... f8e8  11. e1g1  11... d6e5  12. f3e5 The most natural and conventional capture, but I should mention that taking with the pawn has interesting practical value. It has never been tried before and sharpens the game. Black needs to defend accurately. 12... c6c5  13. a2a4 [%c_effect a4;square;a4;type;Interesting;persistent;true] A good prophylactic move to prevent the move ...b7-b5. 13... c5d4  14. e3d4  14... b8c6 Black has many candidate moves and enjoys near-equality with them. 15. e5c6  15... b7c6  16. a4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] Fixing the pawn structure before Black can play a5 himself. 16... a8b8  17. d1d2  17... f6e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] Black achieves comfortable equality now. 18. c3e4  18... d5e4  19. d3c4  19... d8d6  20. f1e1  20... c6c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] 21. d4d5  21... c8d7  22. a1c1  22... f7f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Black starts advancing the pawns on the kingside while the passed d-pawn is well blocked. But the position is still equal. 23. d2c3  23... f5f4  24. c4f1 Bringing the bishop back to the defense and attacking the c-pawn. 24... b8c8  25. c3b3  25... e4e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] 26. f2e3  26... f4f3 A very interesting pawn sac that forces White to find the difficult moves to defend. 27. e3e4 [%c_effect e4;square;e4;type;Mistake;persistent;true] Allowing a second pawn sac that begins a wonderful king hunt. 27... f3f2 [%c_effect f2;square;f2;type;Brilliant;persistent;true] 28. g1f2  28... d6h2 [%c_effect h2;square;h2;type;GreatFind;persistent;true] A fantastic idea. The king is caught in the middle of the board. The attack is objectively winning. 29. b3e3 [%c_effect e3;square;e3;type;Inaccuracy;persistent;true] This makes things even worse, but even after the computer suggestion 29... c8b8 [%c_effect b8;square;b8;type;GreatFind;persistent;true] 30. b2b3  30... e8f8 [%c_effect f8;square;f8;type;Inaccuracy;persistent;true] This is an inaccuracy, but it's very difficult to spot the winning line. 31. f2e2  31... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] The third pawn sac of the game. 32. b3c4  32... b8b2  33. e2d3  33... h2e5 [%c_effect e5;square;e5;type;GreatFind;persistent;true] Preparing a deadly check on b3. 34. c1c3 The only move. This is a very interesting position that can be analyzed for hours. Due to time limitations, I'll limit myself to pointing a few interesting ideas and variations. 34... d7a4  35. f1e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] Not the best defense, but the moves for White and Black are all hard to find. 35... f8f2 [%c_effect f2;square;f2;type;Inaccuracy;persistent;true] A fantastic idea, but not enough for a win. 36. e3c1 [%c_effect c1;square;c1;type;GreatFind;persistent;true] The only way to defend. 36... f2g2 [%c_effect g2;square;g2;type;GreatFind;persistent;true]
