Subject: Avoid move: Qxe3+, dificult for Fritz8

Author: Fernando Alonso

Date: 09:06:18 05/27/03

In this position Fritz 8 ( v8008) wants to take the e3 pawn for about one and a
half minutes, and after playing QXe3+,Kb1 doesn´t realice white is clearly
winning for another minute or so.

 Shredder 7.04 on a XP1800 32 MB hash shows us how black has little defence
pretty quickly.
