Jun-19-05  Kangaroo: If the score is correct, why did White not take the rook?

53. Qxh3 Qxf2+. 54. Kh1 and I do not see how Black can draw here.

Perhaps, the next move, 54 ... Ra6 is a solution. What do the Fritz users think?

  offramp: Exactly as you said:

53.Qxh3 Qxf2+ 54.Kh1 Ra6 and the threat of ...Ra1+ is too much.

Jun-20-05  notsodeepthought: I also wonder why he didn't take it one move earlier - 52 Q:a3. Perhaps white needed a win in this game and could not allow ... 52 Q:f2+ with perpetual?

  offramp: This was game 4 of the candidates' match, and Kortschnoi was leading 2˝-˝ after the first three games. So perhaps Portisch *was* trying to win.
Nov-29-08  PKNJ: Yes, the point here is that heading into this fourth game of the Candidates quarterfinal, Portisch was already trailing by two full points. So he went in for sharp play, and gave up the exchange for two pawns with 33. Rxc3. And he rejected Korchnoi's sacrificial offer of perpetual check, 51. ... Ra3 (52. Qxa3, Qxf2+).

But Korchnoi's offer of the rook one move later was no perp. If Qxh3, then 53. ... Qxf2+; 54. Kh1, and Kangaroo is correct, Black swings over to the queen's side: 54. ... Ra6, and there is no way to stop Ra1.

Or 54. Qb2, Rh6 mate.

Robert Byrne called Portisch's 52nd move "the most disheartening, most disastrous blunder of the quarterfinal matches for world championship contenders," and said Portisch "did not penetrate the diabolically complex motive of a man who had just vigorously thrust an olive branch at him." (NYT, 5/1/83)

After this game, Korchnoi led, 3.5 to 0.5. He eventually won, 6-3, his last great triumpn in world championship match play.
