Go up one level in this thread


slightly different subject, but a while back you had posted a bad game played by
Crafty where it sacrificed a piece to reach a KRPP vs KRB ending and it lost
after the two pawns were removed.

I have fixed this evaluation term so that it doesn't think KRB vs KR is a draw
if the KR side has the king trapped on the edge or in the corner.  I have played
over a couple of recent losses to see what this did and it fixed all cases quite
effectively.  It _still_ plays the sac in your game, but the PV and later moves
in the real game change so that the king isn't trapped on the edge where it can
get into trouble with the R+B vs R.

Another bug eliminated, approximately 60,000 may remain, assuming one bug per
line of code. :)
