Well, before someone jumps on us, of course this match (actually both) was
*much* too short to reach any statistically reliable result, not even close - so
this is all just wild guesses. But I do agree that Postmodernist did much better
than Crafty when it is about the actual games and don't think Junior would have
much of a chance against it with a 1-10 hardware disadvantage, if PM were not
too unlucky with its book, although this would have to be tested.

One reason might be that Postmodernist is much more aware of king safety issues
and compensation for a pawn than Crafty, so it didn't get surprised by Junior's
sacs so often.

I think Postmodernist is an engine that is just not so well-known and popular,
but that is really pretty strong.

Some time ago I played another little match against Hiarcs 9 at 60/10 with
similar hardware difference, that I stopped at 3.0-3.0. Maybe it just likes my
computers :).
