Thanks but Gerbil is not one of the top amateurs and is clearly weaker than
movei.

I am more interested in programs that at least close to movei's level because I
do not expect programs that are clearly weaker than movei to have a good
evaluation of pawn structure(it is possible that they have it and have
weaknesses in other areas but I know that Gerbil was not designed to be a good
chess program but to be a simple chess program).
