Decision position · Black to move

Pawn structure and mobility

White occupies d4 with pawns and controls d4, d5, e5 with pawn attacks; Black occupies none of d4, e4, d5, e5 with pawns and controls d5, e5 with pawn attacks. Black has 12 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.

Identify the chain's support

White's pawn chain on c3, d4 has c3 at its base. Test whether pressure on that support changes the advanced pawns' stability; piece placement and tactics determine whether a break works.
