cf7 should clear square f7. This worked for me but of course xf7 would be
better.
->  4. So far I've conducted two games between CM 2100 and GNUCHESS. At

->     after 17 moves. At 1 minute a move the game fizzled into a dead
->     drawn position in 52 moves. Both claimed a draw by repetition!
->     This game started as a sharp double king pawn opening with both 
->     programs offering their queen pawn for initiative. Suddenly the 
->     game degenerated into "brownian motion" as both programs became 
->     eager to eliminate material and shuffle their pieces back and 
->     forth. The resulting equal material ending should have been a draw
->     with best play, but as it was conducted was in fact a win from 
->     either side on several occassions!!
->	My assessment so far: a. CM has superior opening book
->			      b. GNUCHESS seems stronger in the middle
->				 game
->                              c. both are equally weak in the ending
->     NOTE: I've yet to try them at higher levels. I know from experience
->     that CM isn't half bad at the higher levels.

->			 Your 2200 fish-at-large
On a sun4 (sparc) I got about 6000 nodes/s.
On a 12 MHz PC-AT-clone I got 300-550 nodes/s.

I have heared that CM is much better on 68kx than on 80x86.
