I'm wondering if Chess Tiger could have problems when being used for overnight analysis. I put up the Deep Blue - Kasparov position in ChessParter 5.1, started ChessTiger with 200M hashtables (the maximum) on the XP 1800 and let it analyse away. However, after about 1.5 hour the nodecounter overflowed, and the next PV that was printed out was cut short, and the branching factor exploded. Either it might be on to something, or it might be having problems with overloaded hashtables. Anybody else seen this kind of problem in very long analysis runs? 00:00:00.0 -1,14 11 164841 Qxc6 dxc6 Kg8 Ra7 Rc8 Rb7 Ra8 Rxb5 Ra1+ Kf2 Ra2+ Kg1 Ra1+ Kh2 00:00:00.4 -1,58 11 193010 Qxc6 dxc6 Kg8 Ra7 Rc8 Rb7 Kf8 Rxb5 Ra8 Rd5 Ra1+ Kf2 Ra2+ Kg1 00:00:00.5 -1,58 12 389392 Qxc6 dxc6 Kg8 Ra7 Rc8 Rb7 Kf8 Rxb5 Ra8 Rd5 Ra1+ Kf2 Ra2+ Kg1 Bc7 00:00:03.2 -2,34 13 1412753 Qxc6 dxc6 Rc8 Ra7+ Kf8 Bd5 Rc7 Ra8+ Ke7 Ra5 Ke8 00:00:09.3 -2,34 14 4552303 Qxc6 dxc6 Rc8 00:00:18.8 -2,36 15 8193181 Qxc6 dxc6 Kg8 Bd5+ Kh7 Be6 Bc7 Ra7 Bb6 Rf7 Ra8 c7 Ra1+ Ke2 Ra2+ Kf3 Bxc7 Rxc7 00:02:37.0 -2,20 15 68200230 Qe3 Qd7+ Kg8 Qxd6 Rf8 Qe6+ Kh7 Qe7 Rg8 Bf3 Qxc3 Qe6 Qxb4 d6 Qb1+ Kf2 Qc2+ Be2 00:04:10.3 -1,30 16 110849691 Qe3 00:04:20.5 -1,30 17 115758982 Qe3 00:11:53.6 -1,44 17 336003972 Qe3 Qxd6 Re8 h4 Re7 Bf3 Qc1+ Kf2 Qd2+ Kg3 Qe1+ Kg4 e4 Qc5 exf3 Re6 Rxe6 fxe6+ 00:18:17.0 -1,48 18 525918038 Qe3 Qxd6 Re8 h4 h5 Bf3 Qc1+ Kf2 Qd2+ Be2 Qf4+ Kg1 Qe3+ Kh2 Qf4+ Kh3 Qxf5+ Kh2 00:29:14.0 -1,48 19 860756587 Qe3 Qxd6 Re8 h4 h5 Bf3 Qc1+ Kf2 Qd2+ Be2 Qf4+ Kg1 Qe3+ Kh2 Qf4+ Kh3 Qxf5+ Kh2 01:07:39.2 -1,54 20 2044093935 Qe3 Qxd6 Re8 h4 h5 Bf3 Qc1+ Kf2 Qd2+ Be2 Qf4+ Kg1 Qe3+ Kh2 Qf4+ Kh3 Qxf5+ Kh2 02:32:08.3 -1,54 21 432997679 Qe3 Qxd6 Re8 h4 h5 (nothing more for the next 10 hours or so) -- GCP
