Pawn structure and mobility

White occupies none of d4, e4, d5, e5 with pawns and controls none of those four squares with pawn attacks; Black occupies none of d4, e4, d5, e5 with pawns and controls none of those four squares with pawn attacks. Black has 3 legal pawn move choices in this position. Pawn control is geometric, including pinned pawns; legal mobility accounts for king safety. Neither count is an engine evaluation.
