  Benzol: It's a pity this game wasn't played for a few moves more. It would have been interesting to see how it would have panned out. The exchange sacrifice was unexpected.
Feb-03-08  nescio: A pity, maybe, but it is not really surprising. They were very good friends, which is.

Analysis by Rybka 2.3.2:
<20...Ne4 21.Qe2 b6 22.Qe3 Qxe3 23.fxe3 Nc5 24.Rc4 f5 25.Rd1 Kf7 26.a4 Kf6 27.a5> (0.04/19)

Feb-03-08  nescio: <whiteshark> Interesting. I also judged the position as equal, but my idea was to put the knight eventually on the unassailable square d5 where it guards, among others, the square c7. For example 20...Rd8 21.Qb4 Qd7 22.Re1 b6 23.Rac1 Nd5 or 20...b6 21.Qc4 Qxc4 22.Rxc4 Nd5. However, who am I to argue with a computer?
Mar-24-08  nescio: <Benzol: It's a pity this game wasn't played for a few moves more> You can see a continuation in Pachman vs Ivkov, 1960. <The exchange sacrifice was unexpected> Looking at the position again it dawned on me that the exchange sacrifice is virtually forced, because on 18...Rd8 or 18...Re8, 18.Rd1 would be embarrassing. In the game mentioned above Ivkov also opted to sacrifice the exchange, and drew comfortably in 31 moves. It's interesting that Ivkov apparently rejected the sacrifice in Szabo vs Ivkov, 1964, and lost. He must have played for a win in that game, because the draw from Szabo vs Polugaevsky, 1973 is obvious.
