Glaurung should never announce mate unless the PV ends in a mate. Do you use a GUI or some other tool which truncate the PVs? Otherwise, I have a new bug to track down. :-( The current development version of Glaurung is much faster in this position, by the way. On my iMac G5 (which is about half as fast as your Centrino), it announces mate in 21 after 6 seconds and 8 plies, and reduces this to mate in 19 at the next iteration after 11 seconds. 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). Tord
