Pawn flank attacks This patch tweaks some pawn values to favor flank attacks. The first part of the patch increases the midgame psqt values of external pawns to launch more attacks (credits to user GuardianRM for this idea), while the second part increases the endgame connection values for pawns on upper ranks.
