These 2 games were played using hiarcs7.32 interface(PIII450 when both sides
used 64 Mbytes hash tables).
Crafty17.10 let a draw by repetition when crafty's evaluation showed that it
believed that it is better.
I wonder if this bug is only because of chessbase or also a bug in the original
Crafty17.10
Usually crafty17.10 does not let a draw by repetioion when it believes that it
is better and it did only in 2 games out of 84 nunn match games.
I could not reproduce crafty17.10's moves when it allowed a draw by repetition
but it may be a result of some learning.
Inspite of this problem Crafty17.10 has a positive result(45.5-38.5 after 84
games and 17.07 is leading 2.5:1.5 only in the 5 minutes games)
