Na3 b5 20. Rc6 {Up to this point So had played instantly. This is surprising as he has achieved nothing on the queenside. Nakamura continues his kingside attack.} g4 21. Qc2 Qf8 22. Rc1 Bd7 23. Rc7 $2 {I don't like this move at all. Releasing the tension on d6 and a6 is too lenient on Black's position. Asked after the game what they thought of Wesley's play, most of the players agreed that it looked completely wrong and anti-positional. "If it was White to move, I would consider playing Rc6 here" - Anish Giri.} (23. Nb4 $1 Bxc6 (23... Bh6)) 23... Bh6 24. Be1 {removing the bishop from potential g3 moves with tempo.} h4 {here the pawn on g4 is clearly poisoned to an experience KID player.} 25. fxg4 {picking up the gauntlet, this is not good. That being said, I don't know what else he could have done.} f3 26. gxf3 Nxe4 27. Rd1 $2 {This makes things esay for Nakamura to calculate as almost every line wins.} (27. Rxd7 {was a much better try.} Rxf3 $1 {works anyway} (27... Rxd7 28. fxe4 $16) 28. Bxf3 Qxf3+ 29. Qg2 Qxd3 30. Rd1 Bd2 $3 { is the key move. Nakamura did not see this, but he would have found that h3 instead of Bd2 was favorable for Black, and upon reaching this position probably would have found Bd2.} 31. Bxd2 Nf4 {and White is getting mated.}) ( 27. Nf2 Nxf2+ 28. Bxf2 Bxc1 29. Qxg6+ Rg7) (27. Nc5 $1 dxc5 28. Rxd7 Rxd7 29. Qxe4 Bxc1 30. Qxg6+ Rg7 $19) 27... Rxf3 28. Rxd7 (28. Bxf3 Qxf3+ 29. Qg2 Bxg4 { is completely winning.}) 28... Rf1+ $1 29. Kg2 Be3 $1 {A very nice resource. There were other winning moves, but this is fantastic.} (29... h3+ 30. Kxh3 Rf2 {was even more fantastic, and just as winning.} 31. Bxf2 Qxf2 32. Nxf2 Nf4+ 33. Kh4 Bg5#) 30. Bg3 (30. h3 Nf4+ 31. Kh2 Nxd3 {and with the elimination of the knight on d3 White's dark squares fall apart.}) 30... hxg3 31. Rxf1 Nh4+ 32. Kh3 Qh6 {White is up a rook, but his position is hopeless. He is simply getting mated.} 33. g5 Nxg5+ {The rest is a forced mating sequence.} 34. Kg4 { every move wins here.} Nhf3 35. Nf2 Qh4+ 36. Kf5 Rf8+ 37. Kg6 Rf6+ $1 {pretty but not the only way.} 38.
