(D)2r2rk1/p1q1bpp1/1p6/n2R4/8/P4N2/1B2QPPP/5RK1 w - -

Following Kasparov Bxg7 is the winning move. Its from a Game Kasparov - Poritsch
1983. On a 845 Mhz Celeron with 256 MB Hash Deep Shreeder wants to play it after
38 min. More infos about the complete Test at:

And the un the buttom line GS290. Its in German but the Test should be
understandable.

I understand Andreas that the guys from IBM contacted him because the have the
position from him or his website. He didnt say that he has a Deep Blue or
something similar. But it seems that IBM is working on DB anyway!!!!!

I personaly would have concerns to publish this email. But nevertheless Thx 4
the news Andreas.

PS: Nähere Infos gerne auch an mich persöhnlich ;-)
