  perfidious: This game is similar to the following famous trap (Uhlmann vs Fischer, 1970), with a small, but decisive difference: Black neglected to interpolate ....a6, forcing a4.

This allowed Korchnoi to play 13.Bb5, a move impossible in the later game.

Nov-15-14  HSOL: What's the finish after fxe4? Qb2 combining threats along the diagonal with threat on b7 winning the rook making the black queen overworked?
Nov-15-14  Nerwal: <What's the finish after fxe4? Qb2 combining threats along the diagonal with threat on b7 winning the rook making the black queen overworked?>

Yes, 21. ♕b2 is immediately decisive. 21. ♕b5 ♕c6▢ 22. ♕b2 ♕d7▢ 23. ♘xe4 also wins, but why bother.

Mar-28-19  ChessHigherCat: Took me a good 15 minutes of fumbling around:

18. Ng5 Qf6 19. Qxf6 Nxf6 20. Re7 Nbd7 21. Rg7+ Kf8 22. Rxd7+ Ke8 23. Rf7 Nd7 24. Rxh7 Nb6 25. Ne6 Rc8 26. Nc7+ Kd8 27. Bg5#

Mar-28-19  ChessHigherCat: SF likes my variant, too (+5.00) although I'm not sure whether I made things too easy by 18.. Qf6 instead of Qe5

  al wazir: What happens after 15 Rb1 ? If 15...Nc3, then 16. Qb3 Nxb1 17. Qxc2, and black seems to be a piece down. If 17...Qe4, then 18. Qxb7.
Mar-28-19  ChessHigherCat: <al wazir: What happens after 15 Rb1 ?> SF says it's okay (+1) but in that position you can intuit (if you're in-to-it) that giving up the DSB for the rook is suicidal for black. I'm surprised he did it, especially against Korchnoi.
Mar-28-19  Walter Glattke: 20.-fxe4 21.Qb2 Qe5 (Qe1+ Kh2 Qd4) 22.Qxb7 Qf6 23.Qxa8 wins. Al wazir: 15.Rb1 Nc3 16.Qe1 Qe2 17.Qxe2 Nxe2+ 18.Kh2 Nxf4 19.Rxb2 b6 20.Rd1 White advantage
Mar-28-19  Walter Glattke: 15.Rab1 Nc3 16.Qb3 Qa4 17.Qxa4 Nxa4 18.Bxd6 c4 Always lost before 15th move
Mar-28-19  mel gibson: I saw the text move in a few seconds
but wasn't sure where it would lead.

Stockfish 10 has a different idea:

18. gxf5

(18. gxf5 (g4xf5

score for White +2.84 depth 41

Mar-28-19  raju17: Dear Walter the analysis presented by you lacs mate. 22. Qb2 Qe5 23. Qb3+ d5 24. Qxb7 Qf6 25 Qc8+ forcing mate.
Mar-28-19  saturn2: I took 18. Ng5 threatening f3

18.. Qd7 (queen has to guard g7) 19. Nxe4 fxe4 20. Qf6 Na6 21. Rxe4

Mar-28-19  Cybe: Why do not 18... Nd7 ? (If 19. f3, 19... Qf6).
Mar-28-19  goodevans: <Cybe: Why do not 18... Nd7 ? (If 19. f3, 19... Qf6).>

Why not indeed? A couple of possible continuations:

<19.f3 Qf6 20.fxe4 Qxa1 21.Rxa1 Nf6 22.gxf5 Ng4> winning back the piece.

<19.gxf5 gxf5 20.Nxe4 fxe4 21.Rxe4 Ne5> and white's attack fizzles out (22.f4? Qh4! 23.Bg5? Nf3+!).

I guess that's why SF prefers <18.gxf5 gxf5 19.Nh4> to what Korchnoi played, although <19...Nd7 20.f3 Qf6> works here too.

Strange puzzle, this!

  Honza Cervenka: I have found 18.gxf5 gxf5 19.Nh4 (the Knight is taboo for mate on g7) with f2-f3 or Nxf5 in the air. After 19...Nd7 20.f3 Qf6 21.Qxf6 Nexf6 22.Re7 Re8 23.Rg7+ Kh8 24.Nxf5 white's advantage quite apparent despite of black's extra Pawn. One possible funny finish is then 24...Rg8 25.Re7 Re8(?) 26.Bg7+ Kg8 27.Nh6#.
Mar-28-19  agb2002: White has a bishop for a knight and two pawns.

Black threatens Qf6, unpinning the knight on e4 and disputing the diagonal a1-h8.

White can further weaken Black's position with 18.Ng5, threatening Nxe4:

A) 18... Qf6 19.Qb1

A.1) 19... b6 20.Qb5 Qd8 (20... Qe7 21.f3 wins a knight) 21.Nxe4 fxe4 22.Qb2

A.1.a) 22... Qc7 23.Rxe4 Na6 24.Qf6 Qf7 (24... Re8 25.Rxe8+ Qxe8 26.Qg7#) 25.Qxd6 looks winning for White (25... Re8 26.Rxe8+ Qxe8 27.Qf6 Qf7 28.Qd8+ and mate next).

A.1.b) 22... Qd7 23.Qf6 Na6 (23... Qf7 24.Qd8+ and mate next) 24.Rxe4 transposes to A.1.a.

A.1.c) 22... Qe7 23.Rxe4 Qd(f)7 24.Re8+ Qxe8 25.Qg7#.

A.2) 19... Qe7 20.f3 wins a knight.

B) 18... Qe5 19.Qb1

B.1) 19... b6 20.Nxe4 fxe4 21.Rxe4 followed by Re8+ and Qe1 looks winning.

B.2) 19... Qxd5 20.Rxe4 fxe4 21.Qb2 and Black can't protect b7 and g7 at the same time (21... Qf7 22.Nxf7; 21... Qd1+ 22.Kh2 Qd4 23.Qxb7).

Mar-28-19  Walter Glattke: Al wazir, now I found 15.Rab1 Nc3 16.Qb3 Ne2+ 17.Kh2(Kh1) Nxf4 18.Qxb2 fxg4 19.Qxb7 Nd7 20.Ng5 Rb8 21.Qxa7 Rxb1 22.Rxb1 Nxd5 with black counter chances, K+2P for R. If 18.Rxb2? fxg4 no Qxb7 Rb8 or Maybe 17.-fxg4!? absolute crazy then. 18.Qxb7 gxf3 19.Qxa8 fxg2(+) 20.Rfe1 Be5! Looks "good". My crazy match then is continued with 21.Rxb8 Bxf4+ 22.Kxg2 Qxb8 23.Qxb8 Bxb8 24.Rxe2 is similar to all other anaalyses.
Mar-28-19  Walter Glattke: correction "N+2P for R"
Mar-28-19  malt: <Al wazir > 15.Rb1 Nc3 16.Qe1 Q:e1
(16...Qb5 17.R:b2! Qa4 )
17.Rb:e1
Mar-28-19  ChessHigherCat: <malt>: <Al wazir > 15.Rb1 Nc3 16.Qe1 Q:e1 (16...Qb5 17.R:b2! Qa4 ) 17.Rb:e1

Hi Malt, this is very good for white (sorry, I had it backwards):

15. Rb1 Nc3 16. Re1 Qb5 17. Qc2 Nxb1 18. Rxb1 Qb4 19. Bd2

Mar-28-19  lost in space: I do not see how this is completely winning.

18. Ng5! Nd7! 19. f3 Qf6 20. fxe4 Qxa1 21. Rxa1 Nf6 22. gxf5 Ng4 23. fxg6 Nxh6 24. gxh7+ Kg7

Much better for white, but not 1:0
