[D]2rr3k/1p4p1/1P2b2p/p1Bnpp1q/8/Q1P2PP1/P6P/RB3RK1 b - - 0 26

Solution times (amd 1.6ghz):

Yace       not in 5 min
Crafty     not in 5 min
Aristarch  3:48 min
Gromit     3:12 min
Ruffian    44 sec
CM9000     5 sec

Seems like the strong amateurs are using pruning techniques that cause the
solution to be missed.  Ruffian and Yace have no problem, perhaps they don't use
null move in the way others do?

How does Chess Tiger do on this?
