Don't be too hard on yourself Dr. Hyatt, Fritz 7 although close to accurate
gives an eval of -0.81 pawns and Shredder is a little worse than Crafty at
-4.96, well Chess Tiger 14.0 is "out to lunch" between -12 to -11+ pawns!

Sorry Christophe! You need to fix this problem before you release Chess Tiger
15.0.
