Dec-08-08  lonchaney: Very, very nice! The Anderssen - Morphy's touch in this one.
Jan-04-09  KingG: Yes, brilliant Queen sacrifice.
Feb-12-09  arsen387: why isn't this Q sac more famous? it's outstanding!!
Feb-24-09  KingG: <arsen387> There are many brilliant games that go unrecognized because they weren't played by the likes of Fischer or Kasparov. You can bet that if this had been played by one of them there would be at least 10 pages of kibitzing on what a fantastic game this is.
Aug-29-09  KingG: This should be Game of the Day at some point, although someone else will have to come up with the pun.
Nov-08-09  MrMelad: Cool queen sac! A test pun is "courageously divorced".
Nov-08-09  Steven87: Amazing queen sac.
Nov-08-09  computer chess guy: The Queen sac is flashier, but the simple 14. ♔h1 also gives White a winning position. After ...0-0 15.f5 Bxd5 16.Bxd5 Nc7 17.Bxa8 White has won an exchange and has strong threats against the castled King. Alternatives are even worse for Black.
Jun-27-11  meppi: 7. e4 is also really nice, a good idea to give away pawn to allow bishop to support centralized night. Similar positions can probably be found in other games where an e4 or d4 gambit is good also
Sep-18-15  mikealando: Wow!!
Dec-30-17  fispok: Nikky Kreuger maybe? The queen for three pieces is nice, but the rook sac after for tempo on the king is the real jewel.
Dec-30-17  bachiller: Kuz net's off.
Aug-11-24  mel gibson: I wasn't sure.

Stockfish 16.1 chooses a different ply:

18. Bxb3

(18. Bxb3 (1.Bxb3 Qxb5 2.Nd6 Qa6 3.Nc4 Nc6 4.Be3 Rc8 5.Bxc5+ Kg8 6.Ne5 h6 7.Nxc6 Rxc6 8.Ne7+ Kh7 9.Nxc6 Qxc6 10.Bxa7 Re8 11.Rac1 Qf6 12.Rcd1 Re2 13.Bc4 Rb2 ) +4.70/38 165)

score for White +4.70 depth 38.

if I force SF to play the game ply it's weaker:

18. axb3 Qxa1

(18. .. Qxa1 (1. ... Qxa1 2.Be3 Qb2 3.Nd6 h5 4.Nc7 h4 5.Nxf7 Rh5 6.Ng5 d6 7.h3 Nd7 8.Nxa8 Nb6 9.Nxb6 axb6 10.Rd1 Ke7 11.Re1 Kd8 12.Bd5 Qf6 13.Bc6 Rh6 14.Kh1 Qf5 ) -3.37/43 240)

score for Black -3.37 depth 43.

Aug-11-24  TheaN: Very aggressive play from White rewarded... personally I don't think this Sunday is TOO difficult because it kind of plays itself, and frankly it's cooked also because 18.Bxb3 +- wins too and is even stronger in theory.

<18.axb3 Qxa1 19.Be3!> is quite a slap in the face for Black though, where White purposefully goes a ♗♗♘:♕♖ because the Black king is so terribly placed the continues threats will win White enough material back.

In the position at hand, Black can't save both the queen and c5, except with 19....Qxf1+ 20.Kxf1 d6 but that loses a rook and the game to 21.Nc7 +-. So <19....Qb2> not many alternatives, White's covering all critical squares <20.Bxc5+ d6 (Ke8?? 21.Nc7#; Kg8 21.Ne7+- is similar as the text) 21.Bxd6+ Kg8 (Ke8? 22.Re1+ Kd7 23.Re7+ Kc8 24.Rc7#) 22.Ne7+ +->:

Here's where the forced line ends, and White also kind of lost the ball after 22....Kf8 23.Re1?! +1, whilst 23.Nf5+ Kg8 24.Nd8! +2.5 is more consistent to keeping Black tied up. I can understand White wanted to force it a bit and Re1 is a useful move. I kind of saw up to Ne7+ and not sure if I'd calculate it in full: 18.Bxb3 +- is the logical move and even better in this case, axb3 is quite a risk.

  saffuna: Just glancing at the puzzle position, black is far ahead in material, queen vs. two minors.

But both black's rooks and the queen knight are worse than useless, and the king is in the middle. And those pieces never moved.
