rn3rk1/pp2ppbp/6p1/8/3PP1b1/5N2/q2BBPPP/1R1Q1RK1 w - - 0 1 I had Hiarcs 7.32 search the above position for several hours to a depth of 11 ply, and it wants to play Rxb7 scoring this +0.69. However, in looking at Fritz' opening book, the move is not mentioned, only Bg5, Be3, and d5. This position arises from the Grunfeld Exchange, D85 as follows: 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Nf3 c5 8. Rb1 O-O 9. Be2 cxd4 10. cxd4 Qa5+ 11. Bd2 Qxa2 12. O-O Bg4 I searched the 2 million games opening database and found six occurrences with no names that I recognized. In the six games, White drew 3 and lost 3 (1.5-4.5), so that indicates the pawn should be left alone. But this brings up my point? Is Hiarcs heading for trouble? Is the pawn poisoned, but in such a deep line that computers can't see it in reasonable time? And will all computers make this mistake, if it is one? I'm interested in what other computers and other people have to say about this position. How about it? Chuck
