Increase the mg->eg gradient for the PawnlessFlank malus Just a change of value to S(19, 84). Also somewhat of a follow up to the recent tweak in definition of KingFlank. I tried a lot of other values before this, increasing and decreasing but with little success, and before giving up I wanted to try tweaking the middlegame and endgame values in the opposite directions. I guess this is somewhat lucky.
