  patzer2: Instead of 11...gxf6 ± (+0.70 @ 36 ply, Stockfish 10), perhaps Black can improve by avoiding the doubled pawns with 11...Qxf6 ⩲ (+0.34 @ 37 ply, Stockfish 10) as in Black's win in Kamsky vs Judit Polgar, 1994.
Sep-18-19  NrthrnKnght: Bh7 is better

Checked that on Stockfish 10 -
it leads to a draw.

  Jimfromprovidence: Here's another nice one-move puzzle I found in my vault, with white to play and win. Move 14.

  perfidious: <Jim>, nasty, and surprising that such a strong player overlooked this variation of that overloading theme.

  eternaloptimist: It took me 3 or so minutes to solve this puzzle. stages for me in solving this puzzle:
1. I saw that the f6 square could b a potential target 🎯 shortly after examining the position 2. I noticed that I could do a discovered attack on the opposing ♕ by moving the ♗. 3. I saw that f7 could possibly b a potential target as well. 4. I saw that:
discovered attack + interference tactic = winning position Then I knew that 23. ♗g6! is the correct move!
Sep-18-19  stacase: The White Bishp’s motor is running, where does he want to go?

Oh! How ‘bout g6, that will give Black nothing but bad choices trying to thwart the attack on his Queen and King.

Ha! Black tipped his King over

Sep-18-19  SugarDom: I thought e4 followed by Qd2 fork.

  Breunor: I saw 23 Bg6 right away, but I thought Qe6 holds; it took me a while to see that after Qe6 white has Bf5!

  Breunor: To add to Patzer 2 's analysis, the game really seems to turn against black with 15 Na5.

Best according to the computer is h5:

1) =0.00 (25 ply) 15...h5 16.O-O Rh6 17.Qd2 Qxb2 18.Nd5 Bxd5 19.exd5 Ne7 20.e4 Rg6 21.Rab1 Qd4+ 22.Kh1 Rc7 23.Qa5 Rd7 24.Qe1 Rc7 25.Rb4 Qa7 26.Rb1 Qd4

After the text move, we have:

1) +0.95 (21 ply) 16.O-O Ke7 17.Qe1 Nc4 18.Nd1 h5 19.b3 Na3 20.c4 Qc5 21.Nc3 b5 22.Rc1 bxc4 23.bxc4 Nxc4 24.Bxc4 Qxc4 25.Nd5+ Bxd5 26.Rxc4 Bxc4 27.Rf2

So this is where black starts to go wrong.

Jan-17-21  andrewjsacks: Beautiful, study-like move.
Jan-17-21  Walter Glattke: 23.Bh7? Rxg2+ / 23.Bg6! Qe6 24.Bf5 /23.Bg6 Qxd1 24.Qxf6+ Kd7 25.Qxf7+ /23.Bg6 R6xg6 24.Rxd5 Rxg2+ 25.Qxg2 Rxg2+ 26.Kxg2 Nc6 2R for N + P

  al wazir: Nice. I didn't come close to getting it.

I was sure that the answer had to be a ♗ move, discovering the attack on the black ♕, but I didn't see that Bg6 wins the big material.

Jan-17-21  Refused: f6 is the key square for the white attack, if white can crash in there it's curtains. There's a discovered attack on the queen. So: 23.Bg6+-
Multi purpose move. Closes the g-file (cuts out any shenanigans on g2) and cuts off the defense for the f6-pawn. a.)23...Qe6 24.Bf5 and the queen has run out of squares. 23b.) 23...Qxd1 24.Qxf6+ Kd7 25.Qxf7+ Kc6 26.Be4+ then it's time to collect on the queen. Anything else also leads to murder along the f-file.

  Messiah: Not a super difficult puzzle, still, I found the exact solution after an alarmingly long thinking. Today's quote on the main page is the following:

'It is a profound mistake to imagine that the art of combination depends only on natural talent, and that it cannot be learned.' - Réti

Well, let's learn.

Jan-17-21  Brenin: 23 Bg6, blocking both of Black's Rs from critical squares f6 and g2, and discovering the d-file attack his Q, took about two seconds, and then 23 ... Qe6 24 Bf5, trapping the Q, took another three. Sundays are not often this easy.
Jan-17-21  stacase: I'm breaking my personal rule that I have to at least get the 1st move in order to post a comment - because I got it Sep 18th 2019

I missed it this time around because uh I don't know uh well yes I missed the discovered attack when the Bishop moves, I still don't see why Black tipped his king. But always accept your opponents resignation

Jan-17-21  Nosnibor: Not too difficult for a Sunday. Spotted Bg6 within a minute. Nice finish.
