But I found out that most programs still will grab the pawn on c5? According to Graham Burgess author of THE MAMMOTH BOOK OF CHESS on Page 386. Burgess wrote that 1 Nxc5? "This obvious, materialistic move throws away the win! "White's c5 pawn cannot be advanced to the queening square without the help of the king, but this allows Black to counter by attacking the e-pawn" Pachman. Supposing it were instead Black to move, the following variation is enlightening: 1...Bd4 2. Ne1 Bf2 3. Nf3 Kf6 or (3...Bd4 4. Nh4+ Kf6 5. Nf5) 4. Kh5 Bg3 5. Nh4 Bf2 6. Nf5 Bg1 7. Nh6 Bd4 8. Ng4+ Ke6 9. Kg6 [D]8/8/4k1K1/2p1p3/2PbP1N1/8/8/8 b - - 0 9 According to Burgess with this position White will now play Nf6+ follow by Nh7 and then Ng5+., and win easily. But we already analyzed this position and could NOT find how White can force a win. Jorge >Now I can't find the post. > > >Robin
