Pawn structure and mobility

White occupies none of d4, e4, d5, e5 with pawns and controls d4 with pawn attacks; Black occupies d5 with pawns and controls d4, e4 with pawn attacks. White has 7 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.
