  al wazir: I think black would have been able to hold out longer after 21...Rxf6.

For example, 22. Rxf6 Be8 23. Rhf1 Nd7 24. R6f2 Bg6 25. Bb1 Rf8 26. Rxf8+ Nxf8 27. Qf3 Qd6.

White has ♖+♙+♙ vs. ♘+♘. White's ♗ is out of the picture.

Congratulate Stockfish for Rh5-a5 threatening yesterday, found the winning move.

May-02-21  mel gibson: Didn't see that.
There were so many reasonable moves to consider.

I opted for a Rook lift but that had me even.

Stockfish 13 agrees with the text move:

19. Bh6

score for White +2.52 depth 40.

May-02-21  Brenin: Black's mistake was 18 ... Bd7, cutting his Q off from defending the K-side. Instead 18 ... Na6, threatening to open up the Q-side with b5, and if cxb5 then c4 and Nc5, would have kept him in the game.

May-02-21  RandomVisitor: As early as move 10 white had winning chances with 10.Nf3 followed by quiet developing moves:

<44/61 08:53 +3.11 10.Nf3 Nbd7 11.0-0> 0-0 12.Nd1 Ne8 13.a3 Ba5 14.Ne3 Nd6 15.Rb1 b5 16.cxb5 Bc7 17.a4 h6 18.b3 f5 19.Nxf5 Nxf5 20.exf5 Bxd5

May-02-21  Refused: One of those positions.

19.Bh6 screams to be played. after that black's king position just gets mauled, and e5 will also drop off.

Given white's superior development the then mobile pawn center (e4-d5) that should be more than enough compensation for a puny Bishop.

  agb2002: White has the bishop pair for a bishop and a knight.

The position of the white queen suggests 19.Bh6:

A) 19... gxh6 20.Nxf6+

A.1) 20... Kg7 21.Qxe5 looks winning (21... Nb5 22.Ne8+ Kh6 23.Qg7+, etc.).

A.2) 20... Kh8 21.Qxe5 Nb5(e8) 22.Ne8+ Qxe5 23.Rxf8#.

A.3) 20... Kf7 21.Nxd7+ wins decisive material.

A.4) 20... Rxf6 21.Rxf6 looks very good for White. For example, 21... Nf7 (due to Qxe5 and Rxh6) 22.Rhf1 Be8 23.Be2 followed by Qg3+ and Bh5.

B) 19... Ne8 20.Bxg7

B.1) 20... Nxg7 21.Nxf6+ Kh8 (21... Rxf6 22.Rxf6 + - [R+2P vs 2n]) 22.Qd2 Ne8 23.Qh6 Rxf6 24.Rxf6 Nxf6 25.Qxf6+ Kg8 26.Rf1 Na6 27.Rf3, followed by Rg3+, wins.

B.2) 20... Rf7 21.Bh6 wins an important pawn.
