Chessmaster 8000 sees that Qxh1 is losing in only 21 seconds on my PIII-733, but
it takes over 3 1/2 minutes to get the next PV, for Rxc2. Therefore, I suspect
that, "at tournament time controls", CM8000 would play Rxc2, taking the extra
time to find the "non-losing move".

I asked Mr. Flesher what the time controls were for this particular game, but he
has not replied yet. I'm still curious....
