DJ7 plays very "speculative" chess.  No doubt about it.  And it seems to do
rather well at it.  I think most people know, it's my favorite program.

This move isn't exactly "simple" to a human, but to most programs (commercial
and amateur) it is.

It's like DJ7 has all this amazing talent, and knowledge.  It can find things
most others will never evalaute.  But sometimes, I think it lacks "common sense"
in a computer chess kind of way.

Uh hum.......like pawn endings.  I've seen it blow more of those than anything
else.
