Expand outposts to minors shielded by pawns Allow any pawn in front of a minor piece to replace the pawn protection requirement for outposts. +-------+ +-------+ | . . o | | o . . | o Their pawns | . o x | | o . . | x Our pawns | o N . | | x o B | N,B New (reachable) outpost | . . . | | . _ . | _ Reachable square behind a pawn +-------+ +-------+ N outpost B reaches outpost We want outposts to be secured by pawns against major pieces. If a minor is shielded by any pawn from above, it is rarely at the same time protected by our pawn attacks from below. However, the pawn shield in itself offers some degree of protection. A pawn shield will now suffice to replace the pawn protection for the outpost (and reachable outpost) bonus. This effect stacks with the existing "minor behind pawn" bonus.
