Kibitzer's Corner
Apr-28-06  Hesam7: Both players give the following line:

25. Nbxc5 bxc5 26. Qd7 Re7 27. Qd5

and think that Black's position is on the verge of collapsing. Portisch did not saw 27. Qd5 so he went for the combination that occured in the game. Here are the comments of the players at the end of the game:

<31... Rxe5

PORTISCH: Unfortunately when I started the combination on the 25th move I did not see this simple reply. I had counted only on 31... Rxc1+ which would have lost, since the White rook could not be taken because of mate. After the text the game is drawn.

32. Bb2 Drawn

SPASSKY: There remaine three minutes on my clock for the following nine moves, and I accepted the draw. perhaps Black has some positional advantage at this point.>

  zydeco: Spassky was lucky to get through the early stages of this tournament without a loss. He chooses a slightly passive variation. Portisch gets a nice advantage without facing any real counterplay.

Both players thought that 19....bxc5 would have been better for black.

Portisch could have won an exchange with 22.Bxd7 Qxd7 23.Nf6 but hoped for more.

Spassky saw the winning line with 25.Nbxc5, which Portisch missed.

Dec-14-14  morfishine: <25.Nf6> looks good too

Very interesting sequence at the end

*****

Apr-18-20  edubueno: BS was really happy after the last 2 games results, since he was closed to loose both against Larsen and Portisch. Probably 25 Nf6 is not so effective because of Te6! and Black obtains a resistive position.
