Subject: Question on passed pawns.

Author: William Bryant

I'm looking for suggestions or comments about handling passed pawns in the
program.

The specific area of trouble is when doubled pawns are passed.

At present I only extend on the most advanced of the doubled passed pawns
and only evaluate the most advanced of doubled passed pawns as a passed pawn.
The other pawn is simply a doubled pawn.

When testing this on certain test suites, the version that considers both
doubled pawns as passers did a little better, which is counter-intuitive.  It
needs a lot more testing, but I'm look for comments or previously gained
experience.
