Chessmaster 8000 sees that Nxf1 is very bad in 10 seconds (PIII-733). After 0:16 it sees that Rxb1 is also pretty bad. After 0:21 it sees that Kf8 is not quite so bad, but not looking good. After 0:37 it sees that Rc8 is slightly better, but still not good. After 1:05 it sees that Rc8 is actually worse than expected. After 1:23 it sees that Kf8 is better than Rc8, but still likely to lose....
