Subject: another test position based on my correspondence game

Author: Uri Blass

The test is to find exd5
You can see that Gandalf4.32h cannot solve it in 20 minutes on p800(32 mbytes)

I hope that the test is correct because Gandalf high scores make me doubt the
test but I remember that after analysis based on comp-comp games between Deep
fritz and Junior5.9 I found that white has probably no advantage after exd5.

Deep Fritz could not win Junior5.9 and Deep fritz is supposed to be the better
program.

I also remember that the score of Deep Fritz went down to 0.00 after I gave it a
long time to analyze after the forced line
