This position has a nsty habit of crashing engines, even the odd comercial engine like my Frtiz 4. [D]R6R/3Q4/1Q4Q1/4Q3/2Q4Q/Q4Q2/pp1Q4/kBNN1KB1 w - - 0 1 This is the output from my chess engine. Can someone verify the following perft results with their engine? depth 1 nodes= 218 depth 2 nodes= 99 depth 3 nodes= 19073 depth 4 nodes= 85043 depth 5 nodes= 13853661 depth 6 nodes= 115892741 Also look at Peters perft test web page for good perft tests and results . http://homepages.caverock.net.nz/~peter/perft.htm Cheers, Tom.
