  al wazir: <Anastasia: 32..Bc6 33.Rg6 Qxd7 34.Rg8+ etc.> Thanks. Yes, 33...Qxd7 loses to 34. Rg8+, but it's not forced. What happens after 33...Qxa2 or 33...Qf7?

  al wazir: <Anastasia> OK, 32..Bc6 33.Rg6 Qf7 34. Rg8+ Kxd7 (or Ke7) 35. Rg7 is just like your variation. But 32...Qxa2 34. Nf6+ Kf8 35. Rg8+ Kf7 (Ke7?) 36. Rxc8 Qxe2 37. Rxc6 Qxe4 is less clear.
Aug-07-05  Anastasia: <al wazir> Yeah, I knew the knight capture wasn't forced, & tried to consider all the non-taking moves. It seemed to me like white kept the material plus & the passed pawn, but maybe I underestimated Qxa2.
Aug-16-05  patzer2: What a strange and wonderful tactical game! White passes up several easier winning tactical shots to go for a surprising Queen sacrifice for three pieces and a decisive advantage.

As <Honza Cervenka> noted, White had a clear win in 22. Nxd5! He also had a much easier win with the simple 26. cxb4 fxg5 27. Bd3 , due to his two extra pawns and the exposed Black king position and weak pawns.

However, White certainly earns points for style with the flashy Queen pseudo-sacrifice 26. Qxb4!, forcing the play which follows and leading to a winning double attack after 30. Nf6!

After 30. Nf6! White threatens to win the Queen after 31. Nc7+! (either with a Knight Fork or via discovered check if Black takes the Rook) or to win the enprise Bishop with the pawn. Either way, White is up decisive material and has the initiative against a shattered Black position and exposed King position.

Aug-17-05  patzer2: Here's a breakdown of the combinations discussed, using Fritz 8 to play it out move-by-move:

<22. h4> White misses a relatively easier win with <Honza Cervenka>'s suggestion 22. Nxd5! Bxd5 (22... Nxd5 23. Qxb7) 23. Qh3+ Bh4 24. Nf6+ Rxf6 25. Qxh4+ Kg7 26. Qxb4 . <22... Qb6 23. h5 g5 24. O-O Nxc3 25. bxc3 Be4 26. Qxb4!!> The Queen sacrifice wins style points, but White could secure the full point easier with the simple positional 26. cxb4! fxg4 27. Rd7 Rce8 28. Bd3 Bf5 (28... Bxd3 29. Qxd3+ Kg8) 29. Re1 g3 30. Bxg3 , winning for White due to Black's exposed King and weak pawns. <26... Bxb4 27. Rd7+ Rf7> Even worse for Black is 27... Kg8 28. Rg7+ Kh8 29. Rc7+ Kg8 30. Bc4+ Rf7 31. Rxc8+ Bf8 32. Nf6+ Kg7 33. Nxe4+ Kh6 34. Bxf7 Bg7 35. Bxg7+ Kxg7 36. Nxg5 . <28. Rxf7+ Kg8 29. Rg7+ Kf8 30. Nf6!> This creates a decisive double attack, threatening both the Queen and the enprise Bishop. However, White can also win with the surprising 30. Rg6! Qc5 31. cxb4 Qd5 32. Bd6+ Kf7 33. Ne5+ Ke8 34. Rd1 Qxd1+ 35. Bxd1 Kd8 36. Rg8# <30... Qe6> Also losing for Black is 30... Qc6 31. Nh7+ Ke8 32. cxb4 and 30... Rc7 31. Nh7+ Ke8 32. Bxc7 Qc6 33. cxb4 . <31. Nd7+ Ke8 32. cxb4 1-0> Black resigned here instead of facing lines such as 32...Rc6 33. Rd1 a6 34. Nf6+ Kf8 35. h6 Bd5 36. Bh5 Qxe5 37. Nh7#.

  yiotta: <Mack> Borrowing from the theoretical work of Geoff Chandler, I would say 1.c5 is primarily intended to provide a flight square for the white queen.
Oct-30-21  Brenin: I missed 26 Qb4, and instead found 26 Rd7, which I think gives a small advantage to White. For example, 26 ... Bxb1 27 Rxe7+ Kg8 28 Rg7+ Kh8 29 Rb7+ Kg8 30 Rxb6 axb6 31 Nf6+ leaves White 2P ahead, or 26 ... Qe6 27 Nf6+ Rxf6 28 Rxe7+ Qxe7 28 Bxf6 Qxf6 29 Qxb4 Qxc3 30 Qe7+ with a similar result.

  drollere: i also liked Rd7, which may mean it is a bad move. but rook on the far rank is also key to the game, so it can't be too bad.

  Gregor Samsa Mendel: To take a stab at the question <al wazir> asked in 2005, after 32..Bc6 33 Nf6+ Kd8 34 Rd1+ looks grim for black.
Oct-30-21  mel gibson: Too difficult for me.

26. Qxb4

(26.

score for White +8.75 depth 34.

Oct-30-21  Cheapo by the Dozen: I totally overlooked the game move.

Instead, I went with Rd7, which relies on similar themes but offers much less of an advantage.

  Dionysius1: Annoyingly I looked at Qxb4, couldn't see the point and played Rd7 immediately instead.

Someone said if you find a good move look for a better one.

Mind you, someone said don't get old and slow and a lot of good that did me,

  agb2002: White is two pawns up.

Black threatens Bxb1 and fxg4.

Black's weak second rank suggests 26.Qxb4:

A) 26... Bxb4 27.Rd7+

A.1) 27... Kg8 28.Rg7+ Kh8 29.Rc7+

A.1.a) 29... Kg8 30.Bc4+ Rf7 31.Rxc8+ Bf8 (31... Kh7 32.Rh8#) 32.Nf6+ Kg7(h8) 33.Nd7+ wins decisive material.

A.1.b) 29... Rf6 30.Rxc8+ followed by 31.Nxf6 wins decisive material.

A.2) 27... Rf7 28.Rxf7+ Kg8 29.Rg7+ Kf8 30.Nf6

A.2.a) 30... Kxg7 31.Nd7+ Kf7 32.Nxb6 axb6 33.cxb4 wins a piece.

A.2.b) 30... Qa5 31.Nd7+ Ke8 32.cxb4 looks winning.

A.2.c) 30... Bc6 31.Nh7+ Ke8 32.cxb4 as above.

B) 26... Qxb4 27.cxb4 fxg5 28.Rd7 Rf7 29.Bd6 Re8 30.Rxa7 wins a third pawn.

Oct-30-21  saturn2: After missing yesterdays mate I got this one with main ideas. 26.Qxb4 sacrifices the attacked queen and after Bxb4 there is 27.Rd7+ White will keep its initial material advantage .

  Dionysius1: If 27...♔g8 28. ♖g7+ ♔h8 then 29.♖c7+ ... is a bit of a heart raiser: the defence of the c4 square is blocked now.
Oct-30-21  Whitehat1963: Man! There is a lot going on in this complicated position every step of the way. I hate to admit it, but it is way beyond my understanding. I cannot find the threats, do not see how black counters or avoids them, and even in the final position I do not see how it is hopeless for black. Maybe I should abandon my dream of becoming the world chess champion.

  raymondhow: Like others I went for 26.Rd7, thought there was a mating net if black dared to take the queen. Of course, black need not dare. Looks like I might have only three solves this week, sigh.

  Jimfromprovidence: <Dionysius1> <If 27..Kg8 28. Rg7+ Kh8 then 29.Rc7+ ... is a bit of a heart raiser: the defence of the c4 square is blocked now.>

You can get to that same result after 29 Rxg5+ first, but only if black plays 29...Kh7 after which white has 30 Rg7+, etc.

Oct-30-21  Brenin: <Whitehat1963>: <even in the final position I do not see how it is hopeless for black>. He is down by RBN+2P for his Q, which is a lot, he has no real compensation for this material imbalance, and White's h-pawn is going be promoted soon. Other threats include Bb5 followed by Nc5+ and Nxe6, or Bf6 followed by Re7+, each winning the Q. He could try 32 ... Bc6 but then 33 h6 Bxd7 (Qxh6 34 Nf6+ and 35 Rg8+) 34 h7 and 38 h8=Q+. Any GM would see all this (and more) and resign.
Oct-30-21  johnnydeep: In a flash of sheer brilliance, I saw the first 4 plies instantly. The queen sac followed bt the rook check was just too puzzle-obvious to miss. Am I a GM? Nope - just an occasionally lucky unrated patzer.
