Subject: Fritz5 missed a win against Chesstiger in the wmcc in paris

position:
2r2rk1/2q2pP1/p1b1pp2/1p6/4P3/2Np3P/PPP3Q1/1K4R1
white to move.

Fritz5 arrived to a winning position because it has a better positional
understanding.

Fritz5 played 25.cxd3 and made a draw when 25.Qd2 is winning for white

Fritz5 using 131072Kbytes hash tables needed almost 30 minutes to find
Qd2
Junior5(16 bit version for fritz) needed 10 minutes and 40 seconds
using 31000 Kbytes

This is on pentium200MMX

Genius3 needed 42 seconds to find Qd2 on a pentium100Mh with 15 Mbytes hash
tables.

I think the strong point of Fritz5 is positional understanding
The weak point of fritz5 is the opening book.
In tactics it is sometimes weaker and sometimes stronger than other programs

In the first round against Isichess Fritz5 with white came out of the opening
book with negative evaluation with white.

I believe fritz5's opening book has too many lines stupid humans played.
It is better to delete lines Fritz5 does not like from the opening book of
fritz5.
