Pawn structure and mobility

White occupies d4, e4 with pawns and controls d5, e5 with pawn attacks; Black occupies none of d4, e4, d5, e5 with pawns and controls e5 with pawn attacks. White has 8 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.

White

Isolated pawns: None
Doubled files: None
Passed pawns: None
Blocked ahead: f2 by f3
Pawn chains: g2–h3

Black

Isolated pawns: None
Doubled files: None
Passed pawns: None
Blocked ahead: b5 by b4, f7 by f6
Pawn chains: a6–b5; c7–d6; g7–h6

White's legal pawn moves: a5, axb5, d5, e5, h4, b3, g3, g4

Compare the capture with keeping tension

White's a4-pawn and Black's b5-pawn attack each other geometrically. Compare the recaptures and newly opened lines before exchanging; the contact alone does not prove that either capture is legal or good.

After d5, why does the rook travel through a3 and e3? What must White obtain if the d5/e4 centre is later exchanged away?

Diagnose → choose → calculate → explain the transformation. Consider the opponent’s best resistance, not just the move you want them to make.
