I do not believe it.
I was impressed by Deep Fritz's result in one of the position from my
correspondence games when Gandalf needed more than an hour when Deep Fritz could
see the right move in a few minutes based on Enrique's post.


>not for hiarcs (the more time the better) , not for shredder,


I disagree here.
I analyze positions with Shredder5 and I am not impressed

Here is one example:

[D]rn2kbnr/1bqp1ppp/p3p3/1p6/3NP3/2N5/PPP1BPPP/R1BQ1RK1 w kq - 0 1

This position is from my correspondence game(the game began 1.e4 c5 2.Nf3 e6
3.d4 cxd4 4.Nxd4 a6 5.Nc3 Qc7 6.Be2 b5 7.0-0 Bb7
Shredder5 likes to play 8.e5(probably a bad novelty)

I gave it a lot of time and Shredder needs more than 8 hours to find something
better(Re1)

It means that even p10000 is not enough for shredder to find Re1 at tournament
time control assuming it has no book to use.



The scores of Shredder5(PIII450(192 Mbytes hash) are
Re1 +0.46 5:48 depth 12
e5 +0.47 6:22 depth 12(failed high)
e5 +0.60 7:05 depth 12
e5 +0.48 12:39 depth 13
e5 +0.58 49:02 depth 14
e5 +0.40 93:23 depth 15
e5 +0.32 331:10 depth 16
Re1 +0.33 485:13 depth 16(failed high)

I did not decide if to play Re1 or to play another move.

Re1 is a sacrifice because black can win material by b4 and I have to analyze
Nd5 and Na4 that were played in the past.
