The final, neat move! Black wins by force.
1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4 The Italian is as common nowadaysdays as the Ruy Lopez was before. 3... g8f6  4. d2d3  4... f8c5  5. c2c3  5... e8g8  6. e1g1  6... d7d5 The most direct try for an equality. 7. e4d5  7... f6d5  8. f1e1 The immediate pressure against the e5-pawn is White's best chance. 8... c8g4  9. b1d2  9... d5b6 That is the thing, Black can aslo attack the opponent's central pawn. 10. h2h3  10... g4h5  11. c4b3 According to Megabase, this retreat is recently more successful than 11.Bb5. 11... d8d3  12. f3e5  12... d3f5  13. e5f3  13... f8e8 \"This is a rare move, but people obviously know about it. It is on my course for White; I say White is slightly better in this game,\" said Giri, with mischievous smile on his face. 14. g2g4 Esipenko accepts the challenge. 14... h5g4  15. h3g4  15... f5g4  16. g1h1  16... c6e5  17. f3h2  17... g4g6  18. b3c2  18... e5d3  19. c2d3  19... g6d3 Up to here, everything was more or less forced. White needs to quench the opponent's initiative as quick as possible. 20. d2f3 Thus, the trade of the queens is offered, but at the price of a pawn. Giri, however, had memories that he offered another square for the knight. 20... d3d1  21. e1d1  21... c5f2 Black has three pawns for the piece, and as a rule this translates into more pieces traded=the more valuable the pawns become. Their potential value can improve from three to thenty-seven pawns in theory, which means that Esipenko will need to wisely positon his pieces to actively suppress the pawns. 22. c1f4  22... c7c6  23. d1d2 \"This move is not critical.\" (Giri) And the Dutchman quickly proves why. 23... f2e3 \"After the trade of the bishops I was comfortable. Generally, if I trade the right pieces, and if White does not jump quickly on my king with some Nh2-g4 and Ra1-g1 then I am safe.\" (Giri) 24. f4e3  24... e8e3  25. f3d4  25... b6c4  26. d2f2  26... a8e8  27. a1f1  27... c4d6  28. d4f5  28... d6f5  29. f2f5  29... f7f6  30. h1g2  30... g8f7  31. f1d1  31... h7h5 Using a small tactic Giri brings his pawns into motion. This is why Esipenko needed more pieces on board; it would have been riskier then, pushing the foot-soldiers in front of the king. 32. f5f2  32... g7g5  33. d1d7 \"I think this was his mistake. He should have freed the knight to either f1, or via f3-d4-square and then enter with the rook behind, and then I was not thinking I would be able to win this game.\" (Giri) 33... e3e7  34. d7d6  34... e7e6 Black would love to swap one pair of rooks, when his pawns would move effortlessly. 35. d6d7  35... e8e7  36. d7d8 Not allowing further trades. 36... g5g4 But now the knight is depressed. 37. d8h8  37... f7g6  38. h8g8  38... e7g7  39. g8f8  39... g6g5 More progress is made by Black in the time-trouble. 40. h2f1  40... h5h4  41. a2a4  41... a7a5 Another instructive decision by Giri. He wants to build a self-sufficient queenside setup, put the rook on e5-square and finally push f6-f5. Therefore, the pawn is ideally located on the fifth rank. 42. b2b4  42... b7b6  43. b4a5  43... b6a5  44. f8a8  44... e6e5 All set for f6-f5. 45. f1d2 And Esipenko blunders under pressure, practically blitzing this natural move. 45... g4g3 Esipenko obviously missed an important detail in his calculations. 46. d2f3  46... g5f4 Under a discovered check! Such moves are easily missed, even by top-grandmasters. 47. f2f1
