Sep-09-12  sevenseaman: What a positional smorgasbord! 24. Kf1! I haven't grasped the significance.

  al wazir: 26. Rxd8, followed by Rxf8+, Qxh7+, and Qe7#, would also have worked. But I can understand Unzicker's preference for the ♕ sac.
Sep-09-12  rilkefan: Ok, after recovering from the surprise I think I see the idea of c6 and Kf1. White's plan is to play Bxc6 (and Bxb7/Bc6 is out due to the Qb2), but then Qc3+. But actually white's plan is to clear the d file by tempting black to play ...Bb5 pinning the knight.
Sep-09-12  rilkefan: And having fired up stockfish I see that the more natural 23.Be2 is even more crushing. White gets in a tempo so that after the improvement ...e5 (for luft) Nd6+ comes before Bxh3+. Anyway.
Sep-09-12  erimiro1: 23.C6! and 24.Kf1! are so cool
Sep-09-12  Jamboree: Seeing as the FIDE rating system wasn't even first initiated until 1970 and the first reliable ratings didn't get published until 1972, how in the world could Unzicker have a 2545 rating way back in 1954? Nobody had a rating back then, except for perhaps a few eccentric local or national ratings which were not on the Elo scale and which didn't apply to international tournaments.
Sep-09-12  Abdel Irada: Interesting variation if Black accepts White's first sacrifice:

<20. ...exd5?
21. ♗xd5†, ♗e6>

If Black doesn't interpose, the rook on g8 falls.

<22. ♗xe6†, ♔xe6>

If 22. ...♘xe6?; 23. ♕xh7†, winning at least a piece.

<23. ♖e3†, ♔d7>

Other choices are worse.

(1) 23. ...♔f7??; 24. ♖e7#

(2) 23. ...♔f5?; 24. ♕h3† and White wins a queen for a rook: (2.1) 24. ...♕g4; 25. ♖e5† or (2.2) 24. ...♔xg5; 25. ♖g3†, ♔xf6; 26. ♖f3

(3) 23. ...♔d5; 24. o-o-o† (Oooch! Have I mentioned lately how much I love it when my opponents castle with check?) 24. ...♔xc5; 25. f7!, ♕xf7; 26. ♕h2, ♕xa2?! (Black's fundamental problem is that he can't keep the enemy queen off d6) 27. ♕d6†, ♔b5; 28. ♖e5†, ♔a4; 29. ♖d4†, ♕c4 ▢; 30. ♖xc4#/♕a3#/b3#.

<24. o-o-o†, ♔c6
25. f7!, ♕xf7
26. ♕h2, ♕c7>

"I stopped the ♕d6! But I did not stop the..."

<27. ♖d6†, ♔xc5>

If 27. ...♔b5; 28. ♖b6† wins a whole queen.

<28. ♕e5†, ♔b4
29. ♖d4† 1-0>

Sep-09-12  Abdel Irada: Good choice for GOTD and pun, <LTJ>.
Sep-09-12  chessbug: I am sorry for being dumb but
Could someone explain the pun to me?

  LoveThatJoker: <Abdel Irada> I appreciate the compliment! Seeing as how you come up with some awesome lines at the start of your solution posts on the daily puzzle, I'm sure the day a pun of yours is selected as the GOTD pun that it will be an excellent one!

<chessbug> In rock concerts, it is a part in the floor section of the audience where people get together and slam into each other so as to celebrate/"dance" to the music.

Sep-09-12  Octal: Look at this:
12 ... cxd4 13 Ncxd5 Qa5+ 14 Kd1 Nc6 (14 ... Nxe5 15 Nh5! is nice) 15 Qxh7+! Rxh7 16 Rxh7+ Kg8 17 Nf6+ Kf8 18 Ne6#
Sep-09-12  rapidcitychess: I echo Max Euwe: I honestly feel very humble when I study this game.

Although, I feel humble when studying most games. ^^

Sep-10-12  kevin86: Black must interpose his pinning bishop,and leave the queen hanging.

Comical!

  Fusilli: Wow! Unzicker played this game like a crazy bloodthirsty mofo on fire! One of the most fun games I have played through in a while.

  takebackok: Looks like a forced queen sac Wednesday, 26. Qxh7+ Nxh7 (or mate in 2) 27. Rxh7+ kf8 (if Ke8 f7+ & fxg8+ etc) 28. Rxd8+ Be8 29. Rf7+ Kxf7 30. Nd6+ Kf8 31. Rxe8#. Think the simple 26. Rxd8 wins also.
Feb-26-25  saturn2: If white starts by Qh7 after Rh7 Rxg7+ the black king goes to f8 and white is stuck. Therefore 26.Rxd8 and after both Bxc4 and Qxc2 black has nothing and the above moves win for white
Feb-26-25  saturn2: Qxh7 as in the game is working indeed. But my above line also wins
Feb-26-25  mel gibson: Looks like Black is lost in many ways.

Stockfish 17 says:

26. Qxh7+

(26. Qxh7+ (1.Qxh7+ Nxh7 2.Rxh7+ Rg7 3.Rxg7+ Kf8 4.Rxd8+ Be8 5.Nxb2 a5 6.Re7 a4 7.Rdxe8+) +M7/120 9)

White wins _ mate in 7.

Feb-26-25  Hercdon: Nice forcing queen sacrifice to mate!
Feb-26-25  King.Arthur.Brazil: The king thinks that many will see the strong move: 26. Qxh7+ Nxh7 27. Rxh7+ Kf8 28. Rxd8+ Be8 29. Bc6 and the incoming mate is unavoidable.
Feb-26-25  TheaN: <26.Qxh7+> screamed out to be played here, one Black rook already in, the other shaky due to the advance of Pf6. After <26....Nxh7 (Ke8 27.Qe7#) 27.Rxh7+> a couple of patterns emerge that, combined, spell Black's doom.

27....Ke8 allows f7 with tempo, 28.f7+ Kf8 (else fxg8Q+) 29.Rxd8+ Ke7 30.f8Q#, 27....Rg7 allows White to grab a rook with tempo and the same patterns emerge: 28.Rxg7+ Kf8 29.Rxd8+ Be8 30.f7 +-, so the best try might be <27....Kf8> just leaving Rd8 undefended: <28.Rxd8+ Be8 29.f7 Qc1+ 30.Bd1 Qxd1 31.Rxd1 +->.

Only after clicking and reading the kibitzes I realize 27....Kf8 is #4 after 28.Rxd8+ Be8 30.Rf7+! Kxf7 31.Nd6+ Kf8 32.Rxe8#, so believe it or not, 27....Rg7 is actually Black's best move with #7 to follow. Alas, Black's toast if he has to give the queen back to survive, so I get the resignation after 28.Rxd8+.

  keypusher: After 28_Be8 29.Nxb2?, it is still mate in three.
