Here is CM9000's thoughts (Junior personality) on my Pentium-4 1.8 GHz laptop: Time Depth Score Positions Moves 0:01 1/8 -0.59 173274 30.Rc7 Qd8 31.Nc4 Rxa4 32.Rxh7 Qxb6 33.Nxb6 Bf7 34.Nxa4 Rxa4 0:04 1/9 0.05 428419 30.Rc7 Qd8 31.Nc4 Rxa4 32.Rxh7 Qxb6 33.Nxb6 Bg8 34.Rc7 R4a7 35.Nxa8 Rxa8 36.Rxb7 0:08 1/10 0.08 924712 30.Rc7 Qd8 31.Nc4 Bc3 32.Nxa5 Bxa5 33.Qc5+ Kg8 34.Rxb7 Bf7 35.Qe7 Qxe7 36.Rxe7 0:24 1/11 0.35 2615101 30.Rc7 Qd8 31.Nc4 Bc3 32.Nxa5 Bxa5 33.Qc5+ Kg8 34.Rxb7 Bf7 35.Bh3 Qf8 36.Qe7 Qxe7 37.Rxe7 1:08 1/12 0.91 7296538 30.Rc7 Qd8 31.Bh3 g4 32.Bxg4 Bxg4 33.Qc5+ Ke8 34.Rxh7 Rxa4 35.Nc4 b6 36.Qc6+ Kf8 37.Rh8+ Kf7 38.Rxd8 Rxd8 39.Qxb6 3:32 2/13 1.52 21891698 30.Rc7 Qd8 31.Bh3 g4 32.Bxg4 Bxg4 33.Qc5+ Ke8 34.Rxh7 Rxa4 35.Nc4 b6 36.Qc6+ Kf8 37.Qb7 Bd7 38.Rxd7 Thus at 1:08 it sees the entire winning line actually played out in the game (through 34.
