Athlon XP 2.5GHz, all engines using 64mb of hash except for CT14/15 (48mb). Most of the other engines I tested found a mate in 5 and stopped thinking completely, those are listed below the CT14/15 lines. CT14 found it in 13 seconds, CT14 in 7 seconds and DJ6 instantly. Fritz 8, DF7, Shredder 7.04, etc didn't do nearly as well (most found mate in 7-8 and stopped or continued thinking for a long time).
