Hi Rick!

Crafty on a P4 3GHz with 384MB Hash, and 48MB PawnTable:

               12->   1:06   0.97   1. ... Qxb2 2. Qb7+ Qxb7 3. Bxb7 d5
                                    4. Rd1 Kf6 5. Nb1 Bc2 6. Rc1 Bh6 7.
                                    Rxc2 Nxc2 8. Bxd5
               13     1:13   0.79   1. ... Qxb2 2. Qb7+ Qxb7 3. Bxb7 d5
                                    4. Rd1 Kf6 5. Nb1 Bc2 6. Nc3 Bxd1 7.
                                    Nxd1 Bb4 8. Ne3 Rd8 9. Nxd5+
               13     2:40     -1   1. ... Bh6!!
               13     3:44  -0.01   1. ... Bh6 2. Qxh8 Qd2 3. h4 Bd3+ 4.
                                    Bxd3 Qxd3+ 5. Kg1 Ne2+ 6. Kf1 Nd4+
               13->   4:07  -0.01   1. ... Bh6 2. Qxh8 Qd2 3. h4 Bd3+ 4.
                                    Bxd3 Qxd3+ 5. Kg1 Ne2+ 6. Kf1 Nd4+
               14     5:17  -0.01   1. ... Bh6 2. Qb7+ Qxb7 3. Bxb7 Bd3+
                                    4. Ke1 Rb8 5. Rd1 Nc2+ 6. Nxc2 Bxc2
                                    7. Rd2 Bb1 8. Rd1 Bc2
               14->   7:14  -0.01   1. ... Bh6 2. Qb7+ Qxb7 3. Bxb7 Bd3+
                                    4. Ke1 Rb8 5. Rd1 Nc2+ 6. Nxc2 Bxc2
                                    7. Rd2 Bb1 8. Rd1 Bc2
               And still searching...

So it finds the move as well, and look at its score. Back to near-zero again.

Cheers,

Renze
