Try 41. Rc1+ and then run it with Crafty. I don't know why Crafty is making this
mistake. The rest will unfold itself if you run Crafty on two computers.

Crafty will end up with a six-fold TB problem either KQPKQP that leads
eventually to KQQKQQ. But white has _always_ a positional advantage.

So, only if someone "quickly" generates those two six-fold TB's, "The World" has
a chance (just in case Kasparov does not play like a 2800+ rated player and his
team has not yet generated those TB's).

Just in case, you are interested how "my" game continues with Crafty 16.17.
(White was running on a p6/200 128MB RAM and Black enjoyed a pII/300 with the
same amount of RAM, same books, no TB's, same rc-file, and same history. I
interrupted this game since I used a tc of 40/2, and this really takes a lot of
time with those slower systems.)
