 This position happened in a blitzgame of mine vs CM 9000Utz12 (white).
 It's no longer a question of building a slow attack - instead it's already
 there, in full bloom. Or, another way to put it, white has nothing and
 black has everything. So, how do the programs evaluate such a position
 with some time to think?  A few results:


 CM 9000Utz12    25.Qd3   -0.15   Ply 14      64 Mb hash
 Shredder PB     25.Qd3   -0.28   Ply 14     128 Mb hash
 Hiarcs 8        25.Qd3   -0.55   Ply 13     128 Mb hash
 Fritz 8         25.Qd3   -0.59   Ply 14     128 Mb hash
 Ruffian         25.Qd3   -0.69   Ply 14     128 Mb hash
 Chess Tiger14   25.Bh1   -1.50   Ply 14      96 Mb hash
 GambitTiger 2   25.Qd3   -2.26   Ply 14      96 Mb hash


 It was with utmost effort that CM finally realized that it actually
 is *worse* in the diagram position... With a tiny -0.15. CM Utzinger
 has achived great results in comp-comp games and perhaps it's possible
 to adjust the settings in a way that CM sees the danger?! King Safety?

 I'm curious of the evals from new programs like Chess Tiger 15, Shredder 7
 and maybe also Schachfreund Utzinger's latest CM personality (a very promising
 one!)?!  The whole game below.
