23. Nxa6! and if 23...bxa6 24. d6! Qd7 25. dxc7 Qe6 26. cxd8=Q Rcxd8

and white is a pawn up with better position. Mr. So should be able to win this. And as Mr. Giri did not play 23...bxa6, he agrees indirectly.

|Jun-13-18|| ||tpstar: <lost in space> Agree - 23. Nxa6! is a very nice tactical idea.|
The RN vs RN ending starting with 30. Nxb3 was well executed by So, combining strategic and tactical ideas. 33. Rb3 tied Black's pieces down to defending the Pb7, then White traded Pawns with 38. a6 leaving an outside passed Pawn at b3. 42. Rh6 got White's Rook behind Black's Pawns while hitting the Ph7. Then 44. Rh6 created the threat 45. Rxd6+! Kxd6 46. Nxf5+ & 47. Nxg7, inducing 44 ... Rf7 and buying time to trade White's h Pawn for Black's g Pawn, weakening the Pf5. 56. g4 took advantage of a potential Skewer (56 ... fxg4?? 57. Rh5+). Finally, 57. Nd4 threatens 58. Nc6+ winning the Re7 along with 58. Rh5 winning the Pf5 or trading down to a won K&P ending (57 ... Rd7 58. Rh5 Rf7 59. Nxf5).
|Jun-15-18|| ||patzer2: Instead of 15...Bxg2 16. Kxg2 ⩲ (+0.44 @ 24 ply, Stockfish 9 analysis of move 16.?), Black might have been better off maintaining the tension with 15...Be7 = (0.00 @ 25 ply, Stockfish 9 analysis of move 15...?).|
|Jun-15-18|| ||patzer2: Instead of 21...e4 22. d5 ± (+1.45 @ 20 ply, Stockfish 9 analysis of move 22.?), Black could have put up more resistance with 21...exd4 22. Rxd5 ⩲ (+0.59 @ 21 ply, Stockfish 9 analysis of move 21...?).|
|Jun-15-18|| ||patzer2: Black lost his last chance to put any significant resistance with 22...f5, allowing 23. Nxa6! +- (+2.20 @ 22 ply, Stockfish 9 analysis of move 23...?).|
Instead, 22...Kh8 23. Qc4 ± (+1.15 @ 17 ply, Stockfish 9 analysis of move 22...?) avoids giving White a won position on his next move, and just might have given
Black practical drawing chances.
|Jun-16-18|| ||WorstPlayerEver: 16... Bg5 was bad. 16... Rc8=|
|Jun-16-18|| ||patzer2: The computer agrees 16...Rc8 = is better than 16...Bg5?.|
Stockfish 9 gives it's assessment of the better alternative as +0.16 (19 ply) 16...Rc8 17.Qb3 Nd4 18.Bxd4 exd4 19.Qxb7 Rxe2 20.Ne4 Rb8 21.Qxc7 Rexb2 22.Nxf6+ Qxf6 23.Qc8+ Qd8 24.Qxd8+ Rxd8 25.Rc6 Ra8 26.Rdc1 g6 27.Rd6 Rb3 28.Rxd4 Rxa3 29.Rd7.
Stockfish indicates the game move 16...Bg5? gives White too strong an initiative after +0.72 (23 ply) 17.Bxg5 Qxg5 18.Ne4 Qh5 19.e3 Rab8 20.Nc5 Ne7 21.d4 exd4 22.Rxd4 Nf5 23.Rf4 Nd6 24.Qb3 Qe2 25.Qd3 Qxd3 26.Nxd3 c6 27.Rb4 Rbd8 28.Rd4 f6
|Jun-20-18|| ||Albanius: In the final position,
57 .. fxg4
58 Rxd6! Kxd6
59 Nf5+ Ke6
60 Nxe7 Kxe7
61 Kxg4 and W has time to take the e-pawn and stop the h-pawn while B chases the b-pawn.
The protected passed Pe3 then wins.
57 .. Rf7
58 gxf5 Nxf5
59 Nxf5 Kxf5
60 Rh5+ and the outside passed b-pawn should win, similarly
|Jun-20-18|| ||Albanius: <lostinspace> At the end of your analysis of 23 Nxa6! bxa6 24 d6!
W can meet 26..Rxd8 with 27 Rxd8 Rxd8
28 Qc4 and the R endgame looks like a win - W will get an outside passed P.
Alternatively B could play 26..Rxc2 leading to
27 Rxc2 Rxd8
28 Rxd8+ with 2 Rs for Q and the same extra Q-side P.
