EXchess gets the following: (This was run on a slow machine, my 400 Celeron is ~5 times faster) Hash size = 262144 entries, 6291456 bytes Pawn size = 65536 entries, 1048576 bytes Type 'help' for a list of commands.

However, the score for dxe5 is not much different from Bc1 or Be3 (at that depth), so EXchess might have played this move... particularly with some small eval changes. I'll run this deeper tonight. - Dan
