Structures, conversion, calculation

A dozen pawn structures cover most of chess: Carlsbad, IQP, hanging pawns, the Slav/Caro triangle, French/Advance chains, Najdorf-style e5-vs-e4, KID locked centre, fianchetto structures, symmetric open files. Each has known plans for both sides — known for a century.

When you know the structure, transpositions stop scaring you and unfamiliar openings become familiar middlegames. IQP positions play the same whether they came from the QGA, the Caro-Kann Panov or the Nimzo.

Study route: take one structure per week from the plan cards, play three drill games in it, then run the scan to see if your ACPL in that structure's games drops.

Up a pawn or an exchange, players in this band attack harder — and lose. Conversion is the opposite skill: trade PIECES (not pawns), kill counterplay before taking anything else, improve your king, only then advance.

The technique list: rooks behind passed pawns; create a second weakness (one weakness is defensible, two overload the defence); 'do not hurry' — repeat once to reach the time control and to test their patience.

Biggest single leak: grabbing a second pawn while their pieces activate. Activity is worth more than a pawn at every level of chess — including yours.

Candidates first: list two or three moves BEFORE calculating any one of them deep. The one-line tunnel — calculating a single move ten moves deep, and playing it — is this band's signature error.

For each candidate: their most forcing replies first (checks, captures, threats against you). Calculate until the position is quiet, then evaluate: material, king safety, worst piece. Compare candidates at their quiet endpoints, not at their most exciting move.

Blundercheck the winner once — fresh eyes, one second: 'after this exact move, what takes what?' Then commit. Never re-open the analysis after you've stood up, metaphorically: flip-flopping burns clock and confidence.

You've learned attacks win games; now learn when they're actually there. Count attackers vs defenders in the king zone: you need more pieces IN the attack than they have defending, usually by two. Half-committed attacks rebound — every attacking pawn move weakens your own king for the endgame you just created.

Green lights: their knight left the kingside (an f6/f8 knight is worth two defenders), the centre is closed or you control it, you can open a file faster than they can trade queens.

Red lights: your own king airy, centre fluid, their queen eyeing a counterattack. With red lights on, the correct 'attack' is usually a queenside pawn break. The structure decides — again.
