Subject: move 37 in Graz controversial game

Author: K. Burcham

Date: 14:15:55 12/10/03



I cannot get shredder to play the game move of 37.Rg4 that allows black to play
third move of repitition.
did not know this was a mate in X move.
after making the third move of the repitition, shredder shows eval of 0.
so stefan knew when the third move of the repitition was made, his eval went
from a mte in x to 0.


Next move 37.Rg4 allows black to play Kh7 for third move of repetition
