Otherwise, I have a new bug to track down. :-( Don't worry - I'm using Shredder 9 GUI which does truncate the PV. Here's the UCI log data for the mate announcement. Thu Dec 01 12:59:19 2005: from Glaurung Mainz (1): info depth 11 seldepth 48 score mate 19 time 22156 nodes 9612658 nps 433862 pv f4h4 h8g8 h4h8 g8h8 c4h4 h8g8 h4d8 g8h7 a4h4 h7g6 d8d3 f7f5 d3g3 g6f6 g3d6 f6g5 h4h5 g5h5 a2f7 h5g5 d6g3 g5f6 g3g6 f6e5 g6e6 e5f4 g2g3 f4g4 e6g6 g4f3 g6f5 f3e2 f5b5 c1c4 b5c4 e2f3 f7h5 [snip] >The reason for the improved solution time is simple: I am experimenting with >unlimited checks in the qsearch (Glaurung Mainz searches checks only in the >first 3 plies of the qsearch). I've played a few games with Glaurung lately and I have notice something that you have commented on before - in real games Glaurung doesn't seem that good at tactics. This is a bit of a surprise since it is normally excellent a most test positions. Have you thought about disabling most of your extensions to see if these are actually hurting Glaurung in normal gameplay? Regards, Steve
