Bob I hope you see this and can explain. This is the Crafty 15.20 inside of
Nimzo 99 and inside Junior appears to work the same way. Notice the times it
takes for Crafty to move. When this is run under Winboard Crafty plays the
entire variation in only a few seconds. Notice Crafty takes 72 seconds to make
the Mate in 1 move. Crafty searches 10 ply for that move but notice that is
typical of all the moves. It's a mate in 7 I created several years ago (18) to
test some of the old dedicated chess computers.
