Rxc4! as the game goes, you can't really call Rxc4 an exchange sacrifice :-) black gets a pawn for the exchange, plus the passer on b2. this is a good test position - Rxc4 looks like the best move for black, and to test whether omid is right, please give it a try: [D] r1r5/3nbpk1/4qnp1/4p1Bp/1pN1P3/1PP2Q2/4N1PP/3R1R1K b - - 0 26 the game continued ...Rxc4 27. bc4 b3 28. h3 (28. Nc1?! Qxc4! 29. Rxd7? Nxd7 30. Bxe7 b2 -+) b2 29. Ng3 Qxc4 30. Rb1 Rb8, and now, my fritz 7 in chessbase says +0.56 for white, but i think that is rather materialistic. i like black's position here. which other program would play 26...Rxc4! ? aloha martin
