a good soul posted this game on r.g.c.c -- a gem in the r.g.c.c minefield ...
the year was 1985 - a period when Kasparov was still crescending to the top of
his game ....mightbe good PDA test ...a tad too easy for PC I believe

now here's the interesting part -- if leave Crafty think on its own - on my
machine it will search for over 8 minutes without seeing the mate score - but if
I just stop it after two minutes , backup a move and restart it - it will mate
almost instantly - why is that?
