Subject: stalemate guard

Author: James Long

I recently received a game via email that Tristram played
against Gromit.  Tristram had 1 queen, 1 rook and 3 pawns
vs a lone king, and allowed Gromit a stalemate.  I've
tried and tried to reproduce this, but can't seem to get
Tris to replay this move.

My first thoughts were that I should've implemented that
stalemate guard in my endgame eval.  I read about this
in the "Chess 4.5" chapter of "Chess Skill in Man and
Machine."  Doing this is painfully slow, though.  I ran
some suites with it last night, and it's ugly.

Seems to me the stalemate should've been caught in the
search.

Do any of you have a stalemate guard in your evaluation?
Has anybody tried this and tossed it out?
