I have played a bit with pawnstructures, keep pawns so that important squares
can be potentially dominated, while the opponent cannot. It is interesting but
in my case it lead to kind of ehm, "exotic" pawnstructures. Maybe bad tuning of
penalties, I don't know. But my experiences with this type of lookahead in
practical gameplay are not very encouraging so far. A good example of where it
does work, is Crafty's potential passer code (which BTW can be done loopless and
paralel for all pawns, with some fill routines). Do you actually use these kind
of ideas in your eval?
