Subject: Can any engine with book off do a better job than Shredder at diagnosing

Author: Dann Corbit

Date: 10:49:12 04/19/04

... this position from the Evans Gambit?  Shredder has reduced the score to 0.13
pawns and most engines I tried were much farther away from the true value.

On the other hand, all the engines I did try eventually start a slow march
downward with the score.  Some are wildly optimistic (thinking at first that
they are two pawns ahead).
