Apart from the ones mentioned by other people, i used to have an extension for
capturing a pawn that is part of the king's pawn cover. Also an extension for a
pawn moving to attack a piece. Both of these helped on tactical problem sets.
I'm not sure if they helped or not in actual play. I've since taken them both
out, but may try them again later.
