right. of course shredder8 is strong.

but this game was not a BLITZ game, it was not played on a 450 P3,
it was a serious time control on a serious machine.

and the idea behind the moves is (for a human beeing) clear like the sky.

CSTal moves the pieces in a classical way. like Botvinniks trajectories
it knows how to bring them into position.


14...Qc7 {-0.30/18} 15. Bxh6 gxh6 {-0.40/15} 16. Qxh6 Rfd8 {-0.54/16}
17.Rd3 Nh7 {0.00/17} 18.f4 Bf8 {0.01/18} 19.Rg3+ Kh8 {0.01/18} 20. Qh5 Rab8
{0.35/17} 21.f5 exf5 {0.85/16} 22.Rf1 Rd7 {0.84/19} 23.Rxf5 f6 {0.84/18}

you cannot say that shredder8 did not compute not deep enough.

it only computes the wrong moves. but the search depth is ok :-))

18 is not bad :-))

if anybody wants to try out different black moves, i can ask CSTal for the
answer.
