  chancho: Could 50...Nxc5 51.bxc5 Kg6 have drawn?

  chancho: Ok, I think I see it. After 51...Kg6 52.h7! Kxh7 53.Kf5 Kg7 54.e5 fxe5 55.Kxe5 and the c6 pawn will eventually be lost.
Aug-01-07  zluria: Nope! These pawn endgames are easy to solve. Here's a forced line for you: 50 ...Nxc5 51.bxc5 Kg6 52. h7 Kxh7 53. Kf5 Kg7 54. Ke6 Kg6 55. Kd6 Kg5 56. Kxc6 Kd5 and white pushes the b pawn to victory!

  chancho: <zluria> Yes, 54.Ke6 is way better than 54.e5. Thanks.
Aug-01-07  chessamateur: I recall hearing someone say that Onischuk missed an immediate win with 27. Bh6. This is not correct if 27. Bh6? then Black draws.

27. Bh6? Rh1+!
28 KxRh1 Qd1+
29. Kh2 Qd6

and the threat is over.

Declining the rook sacrifice leads to similar outcomes.

27. Bh6? Rh1+!
28. Kh3 Qd3+
29. Kh4 f6 (29. Kg4 Qxe4+! and 30... f5+) (29. any other move then 29... Qd6 wins)

After 29... f6 White should take the perpetual with
30. Qe6+ and 31. Bg7+ in lieu of Black's extra material and threats of g5+ with Rxh3+ possibilities.

Verdict: Onischuk's 27. Qxe7 was correct.

Aug-01-07  belgradegambit: I wonder if Avrukh had any inkling of Qxe7 coming or did his jaw drop?
Nov-01-07  computer chess guy: 23 .. ♕xe4 was preferable to 23 .. ♕xa2.

  whiteshark: <Whitehat1963: What happens on 27. Bxc1?>

< 27...Qd1 <!>> with the idea of 28...Qd6 (and ♕trade-off) for both 28.Bb2 and 28.Bh6.
