  FSR: 22.Nxf7 is strong. If 22...Kxf7, 23.Qe6#.
Aug-04-20  Walter Glattke: 21.-Nd7 is a blunder. 21.-e6, After 21.Nxf7 e5 22.Bxd5 cxd5 23.Nxd8 Qxd8 24.axb5 white wins. Seems the best then, so 22.-Kf7 is a blunder, too, black hasn't seen the mate threatening.
Aug-04-20  Walter Glattke: "After 22.Nxf7" all one move more.
Aug-04-20  stacase: Easier than yesterday.

  al wazir: Black's alternatives weren't very promising: 22...Nf8 23. Nxd8 Rxd8 24. Bxd5+ cxd5 25. Qxe7 Qxe7 26. Rxe7.

Or 22...Rb8 23. Nd6 exd6 (23...Ne5 24. Nxe8 Rxe8 25. dxe5 ) 24. Qxe8+ Rxe8 25. Rxe8+ Nf8 26. Rxf8#.

So he elected to fall on his sword by playing 22...Kxf7.

Aug-04-20  mriddle: <al wazir> after 22. Nxf7 Rb8 23. Nd6 exd6 24. Qxe8+ Rxe8 25. Rxe8+ why not 25...Kf7? I found the initial move, but had trouble finding the most convincing follow-up after 22...Rb8.
Aug-04-20  saturn2: 22. Nxf7 threatens Qe6 and a diagonal mate.  Black loses material to avoid this mate

a. 22...Rb8 23. Qe6 Bg7
(Nf8 24. Bxf8 Kxf8 25. Nh6 Qf4 26. Ngf5) 24. Nd6+ Kh8 25. Nxe8  Bxh6 exchange plus pawn

b. 22...Bg7 23. Nxd8 Bxh6 24. Nxb7 Qxb7 

c. 22...Nf8 23. Nxd8 

Aug-04-20  Brenin: If 22 Nxf7 Rb8 then 23 Nxh8 Kxh8 24 Qe6, threatening Qf7, looks like an alternative winning line, e.g. 24 ... Rg8 25 Ne4 Nf8 26 Ng5 and 27 Nf7 mate.

  agb2002: The black king protects f7. This suggests 22.Nxf7:

A) 22... Kxf7 23.Qe6#.

B) 22... Ra(b,c)8 23.Qe6

B.1) 23... Bg7 24.Nd6+ Kh8 (24... Kf8 25.Qf7#) 25.Bxg7+ Kxg7 26.Qf7+ and 27.Nxe8 wins decisive material.

B.2) 23... Nf8 24.Bxf8 Rxf8 (24... Kxf8 25.Nh6 and mate next) 25.Bxd5 cxd5 26.Nd6+ Kg7 27.Qxe7+ Qxe7 (27... Rf7 28.Nxf7) 28.Rxe7+ and 28.Rxb7 wins decisive material.

B.3) 23... Nf4 24.Bxf4 Qxf4 25.Nd6+ Kg7 (25... Kf8 26.Qg8#) 26.Ndf5+ Qxf5 (26... gxf5 27.Nh5+ Kf8 28.Qg8#) 27.Nxf5+ wins decisive material.

C) 22... Bg7 23.Nxd8 wins decisive material.

Aug-04-20  AlicesKnight: Saw the game line quickly - surprised Black did not look for one of <agb2002>'s lines to keep fighting...
Aug-04-20  alexrawlings: I’ve just discovered the analysis function, how long has that been here? What an amazing function!

Also, I saw 22 Nxe7 and the follow up with Qe6. Nice puzzle.

Aug-04-20  Nullifidian: 22. ♘xf7 is strong, but not forcing. Black doesn't have to accept the sac, but if he does then 23. ♕e6 mates.

If black declines the sac with a move like, say, 22... ♖b8 to protect the rook, then the strongest reply is to offer the sacrifice again with 23. ♘d6. And now the sac can't really be declined because of the same ♕e6#. (Black might push 23... ♙e6, but then the simple ♘xe8 wins the exchange and then you can just trade down into a winning endgame.) So 23... ♙exd6 24. ♕xe8+ ♖xe8 25. ♖xe8+ ♔f7 and now white wins back the sacrificed piece with 26. ♖xh8. White now has two rooks and a pawn for the queen, and black's king is in a dangerously exposed position.

  beenthere240: The engine suggests that 22...e6 is the best way for Black to decline the sac. But what I found surprising is that the recommended continuation for White is to take the h8 Bishop-- not the Rook! Apparently weakening the king's defenses is better than simply grabbing the exchange.

  gawain: If Black cooperates by accepting the knight, the end comes swiftly and neatly. If Black defends better, he can prolong the game for a long time.
Aug-04-20  King.Arthur.Brazil: As some, I feel surprised that Black didn't see a checkmate in 1 move? (23.♕e6#) After 22...e6 23. ♘xd8 ♕xd8 24. ♕g4 ♕e7 25. ♖e3 ♗c8 26. ♖ae1 ♘f8 27. ♖f3 ♕d7 28. ♘h5 ♕e7. Black is paralyzed and White has all conditions to decide the fight. <beenthere240> see that the ♗h8 is a great defender still. Doing the same reasoning with the sequence 22...e6 23. ♘xh8 ♔xh8 24. ♕g4 ♘f8 25. ♖e5 ♗c8 26. ♖ae1 ♕f7 27. ♕h4 ♖d7 28. ♘e4 ♖c7 seems that Black position is worst in the second one. 30.♘d6 is unstoppable, wins the quality also and keeps the dark squared ♗. The Black cannot use his 2♖ for protection as does his K♗.
Aug-04-20  TheaN: <22.Nxf7> is obvious on the account of 22....Kxf7? 23.Qe6#. I'm surprised Black just played into this: I mean, then resign after White's 22nd; you ain't telling me Black actually missed it.

<22....Rb8> is the line I spend most time on. Any defense that doesn't move Rd8 just throws the exchange for no compensation, despite the fact that White may have better moves instead I didn't spend time on that.

In the Rb8 line (which defends Bb7, crucial in some lines), I liked the idea of <23.Qe6!?> SF gives simplifying with Nxh8 and axb5 to be best; probably because White's still dominating the board.

Black doesn't have a lot of moves here, but I missed a very beautiful defensive attempt.

What fails is a bishop move, because Black will lack defenders: ie 23....Bf6 24.Ng5+! Kh8 and I wanted to play 25.Qf7 #10, but much more beautiful is 25.Bg7+!!

25....Bxg7 leads to a smothered mate and Kxf7 26.Qf7+ Kh6 27.Qxh7+ Kxg5 28.h4+ Kg4 29.Bd1+ Kf4 30.Re4#

23....Nf8?! is the move I looked at, but after 24.Bxf8 White's domination counts. 24....Rxf8 (Kxf8 25.Ng5 Qf4 (Kg7 26.Qf7 #6) 26.Qxd5! +-) 25.Ng5+ Kg7 26.Bxd5 +- and even though Black played a successful defense his position is still in shambles.

The surprise defense is 23....Nc5! which seems ridiculous, but after 24.dxc5 Bc8 Black attempts to sac a piece to win an offensive piece back: it doesn't work.

I actually don't want to spoil this move. I'd say this is a Thursday puzzle in itself. White to play 25?

Aug-04-20  King.Arthur.Brazil: <Nullifidian The sequence 22...♖b8 23. ♘d6> exd6 24. ♕xe8+ ♖xe8 25. ♖xe8+ ♔f7 26. ♖xh8 ♗c8 27. ♖e1... Black is in zugswang. Ex.: dxc5 28. ♖xh7+ ♔g8 29. ♖g7+ ♔h8 30. ♖e8+♘f8 31. ♖xf8# or 28...♔f6 29. ♘e4+ ♔e6 30. ♘g5+ ♔f5 31. ♖f7+ ♘5f6 32. g4+ ♔f4 33. ♖e4#. In the last line, 29...♔f5 30. g4+ ♔e6 31. ♘g5+ ♔d6 32. ♖e6# or 31...♔f6 32.♖e6#. Therefore, the Black move e6 seems necessary.
Aug-04-20  DrGridlock: After 22 Nxf7 it is obvious that the king cannot take the knight (mate follows directly on e6).

Among the top 4, Fat Fritz rates them:
... Nf8 (5.40)
... Bxd4 (6.00)
... e6 (6.20)
... Rb8 (6.21)

I admit that I only analyzed the e6 continuation, but there are other paths to analyze, "just to be sure."

Aug-04-20  cormier: 12... Bb7? 12...b4 13.a5 Ba6 14.Ng5 Qc7 15.Nde4 Nxe4 16.Nxe4 Rad8 = +0.35 (24 ply)
Aug-04-20  Brenin: Nice puzzle, <TheaN>. A possible solution (after 22 Nxf7 Rb8 23 Qe6 Nxc5 24 dxc5 Bc8) is the unlikely-looking 25 Qd6, e.g. 25 ... exd6 26 Rxe8+ Kxf7 27 Rxh8 followed by Rxh7+, or 25 ... Qxd6 26 Nxd6 Rd8 27 Rxe7. However, a quiet 25 Qe4 is probably good enough for a win, e.g. 25 ... Kxf7 26 Bxd5+ cxd5 27 Qxd5+ e6 28 Qf3+ Kg8 29 Ne4, with a big positional advantage.

  Breunor: After 22 Rb8 Stockfish prefers N x h8 over Nd6, but both win big time:

1) +7.46 (23 ply) 23.Nxh8 Nf8 24.axb5 axb5 25.Qf3 e6 26.Ne4 Kxh8 27.Ra7 Red8 28.Bxd5 Rxd5 29.Bxf8 Rf5 30.Bd6 Qg7 31.Be5 Rxe5 32.dxe5 Qe7 33.Nd6 b4 34.Rea1 h6 35.Rxb7

2) +6.08 (22 ply) 23.Nd6 e6 24.axb5 Bxd4 25.Nxe8 Rxe8 26.Bxd5 cxd5 27.c6 axb5 28.cxb7 Qxb7 29.Be3 Bxe3 30.Qxe3 Qb6 31.Qxb6 Nxb6 32.Ra5 Nc4 33.Rxb5 Kf7 34.Ne2 Kf6 35.Nd4 Ne5
