Apr-15-19  saturn2: I saw 27...Qf2 28. Rg1 Bxg2+ 29. Rxg2 Rc1+ 30. Qe1 Rxe1+ 31. Rg1 Rxg1#
Apr-15-19  zb2cr: Hi <saturn2>: In your variation, 28. ... Qxg2+; 29. Rxg2, Rc1+; 30. Qe1, Rxe1# is simpler.
Apr-15-19  ASchultz: I took forever trying to make Bg2+ work and eventually gave up and figured, this is a Monday puzzle, I'm missing something simple.

Then I felt silly not noticing the back rank weakness a bit earlier.

On the bright side, considering ...Bxg2 made it easy for me to verify Qf2 actually worked after Rg1, because I noticed the g2 pawn's weakness.

  ChessHigherCat: Qf2 threatening Rc1 (if RxQ) and if not Qxf8# or Qxg7#, i.e., ougaaaaaaaa ougaaaaaaaaa.*

The best defense is Rg1 followed by Qsac on g2, as befits a Monday, Rxg2 Rc1+, useless Q interposition and mate

Apr-15-19  JohnDMaster: Easy solve, this is one of my favorite games to teach my students!
Apr-15-19  Walter Glattke: 27.-Qf2 28.Rg1 Bxg2+ 29.Rxg2 Rc1+ 30.Rg1 Qxg1# or 30.-Rxg1# if 27.-Bxg2+? then 28.Kg1! e.g. 28.-Qg4 29.Qg3! or 28.-Rc2 29.Qe8+ Kg7 30.Qxf7+ Kh6 31.Qf4+ white wins. 27.-Qf2 28.Rg1 "only move": 28.Qxd5 Qxf1# /28.Rxf2 Rc1+ 29.Qe1 Rxe1+ 30.Rf1 Rxf1# / 28.R4a1 Qxg2# or 28.-Bxg2# /28.Qe2 Bxg2#
Apr-15-19  stst: 27...................Qf2, no save..

28.RxQ Rc1+
29.Qe1 RxQ+
30.Rf1 RxR#

OR if
28.QxB or Qg3 QxR#
28.NxR Qxg2 or Bxg2 #

Apr-15-19  stst: after.... 27.....Qf2
the defense Rg1 could not stop Qxg2+
28.RxQ then this R cannot move as K pinned by B, then Rc1+ ===> Q interpose ===> RxQ#

zb2cr scores right!!

  Honza Cervenka: 17.Nd6 with idea 17...Re7 18.Ndxb5 was much better.
Apr-15-19  stacase: 27...Qf2 and the Black Queen threatens mate two different ways. White can't defend against both.

Other than checkmate, threatening mate is the most powerful move in chess, and you don't have to say, "Check"

Do those little hints that come up when you click on [POST KIBITZ] ever say anything about threatening mate?

  malt: 27...Qf2 simply wins
(28.Raa1 Q:g2# )

28.Rg1 Q:g2+ 29.R:g2 Rc1+ 30.Qe1 R:e1#

Premium Chessgames Member
  Breunor: According to Stockfish the losing move is 24 Bxd5 where where's position ranks as -3. G3 is even. 24 g3 Ne3 25 Bxe6 Nxf1 26 Rxf1 fxe6 27 Nd6.

I guess Bxd5 allowing the black player's white bishop on the long diagonal was the critical error.

Apr-15-19  Cheapo by the Dozen: A nice one, returning to the Bobby Fischer Teaches Chess vein.

Don't you mean the vain Bobby Fischer's Teaches Chess?

Apr-15-19  chessneverwas: The position arising if Larsen played 27.h3 is entertaining:

27. h3 Qxh3+ 28. Kg1 Bd4+ 29. Rf2 Qxg2#

Apr-15-19  saturn2: <chessneverwas 27. h3>

My non computer check shows me black is also winning with


a. 28. Kg1 Qh2+ 29. Kf2 Bg3+ 30. Ke3 Re8+

b. 28. Qxe5 Qxe5 29. Nxc8 Bxg2+ 30. Kxg2 Qxa5

  Fusilli: The key moment in the game is 13...c4

click for larger view

It throws the game into very sharp territory. The question one would ask before making that move is how to respond to 14.Bxc4. The first move is easy: 14...Nc5. Then if 15.Qc2 I thought Black would go for Nfxe4. After 16.Ndxe4 Bf5, the piece eventually comes back. But then the computer says White is better, and instead Black should play the much stronger 15...Ng4.

So, 15.Qc2 is bad. If 15.Qf3 instead, I thought Bg4 would be nice, but again the computer says no. Instead, 15...b5! is the way to go.

Trading the b-pawn for the e-pawn gives Black active play and compensation for the pawn.

White also has 15.e5, and the game is sharp. What Larsen played (14.e5 followed by 15.Nxc4) is probably the best response.

If not , what a match it would have been.

  gawain: A subtle yet stunning finish.
Apr-15-19  Nosnibor: The nice thing about the final position is that all black`s pieces with the exception of the King are en-prise.
Apr-15-19  Andrew Chapman: Who would find 24.g3? Who would not balk at opening the diagonal against the king?
Premium Chessgames Member
  Diademas: Two out of Blacks three pieces are en prise.

So what do do?
Put the third one en prise: Qf2!

Premium Chessgames Member
  ChessHigherCat: <Andrew Chapman: Who would find 24.g3? Who would not balk at opening the diagonal against the king?>

It's true that for most humans it seems about as inviting as unzipping your fly during a seagull attack in "The Birds", but computers don't have to worry about such things (impeckable logic).

It's funny that SF gives 25...Ne3 as the optimal response because it lets white trade off the LSBs.

Premium Chessgames Member
  beatgiant: After <Andrew Chapman> pointed out 24. g3, I looked at a couple of possible Black attacks.

At first I thought 24. g3 <Rxb5> 25. Bxb5 Ne3. Stockfish suggests <26. Bc6>, guarding the key diagonal, and then 26...Nxf1 27. Rxf1 which it claims is an equal position.

Then I considered 24. g3 <h5>, but then it finds <25. Na7> and goes into some complications, but again about equal in the end.
