Subject: Interesting position -- how to take back?

Author: John Merlino

Date: 16:43:43 06/20/02


This position is from one of the games that Ali Mirafzali posted between CM8000
and a Master named Kamberi, rated 2350.

[D]r1b1r1k1/1p3p2/2p1nq1b/2P1p1pp/1PB1PB2/2N1QN1P/3R1PP1/1R4K1 b - - 0 26

Black has four ways to take back. What does your program say is the best?

CM9000, on a PIII-600, prefers Nxf4. Kamberi played exf4, which CM thinks is the
worst of the four possibilities.
