Subject: test position - delaying the inevitable

Author: Jon Dart

Date: 13:30:38 01/08/03

This position came up in an offline test game, Arasan 6.2 vs. Lambchop 10.88:

[D] 1k6/q7/2Q5/r3pp2/6p1/8/5rPP/5RK1 w - -

White can delay the inevitable with a series of checks, beginning with Qe8+, but
eventually he will run out of checks and lose, I think. This is something that
is typically hard for computers to see. Arasan (White) thought it was fine at
this point.

Crafty 18.10 fails low on this position at ply 13, but then it takes a long time
to resolve the fail-low: I gave it 20 minutes on a Xeon 1.7GHz, and it was still
searching.

Pharaon gets a score of about -2.5 at ply 12, but it went up again on ply 13,
and then like Crafty it just hangs at ply 14 for a really long time.
