After playing several games between CM9000 and Genius 7 manually I noticed in
one particualar game Genius had only 3 seconds left on the clock with quite a
few moves to play before the 50 move rule went into effect so Genius went into
"instant play" mode thereby not forfeiting on time.  CM9000 seemed to be more
conservative using the clock than Genius.
