Positional Play
The long-term strategic elements of a chess position.
Positional play is concerned with long-term advantages rather than immediate threats. Where tactics are concrete, positional judgement is evaluative: weighing the small features of a position to choose a plan.
Wilhelm Steinitz, the first official World Chess Champion, identified the principal elements of a position during the late nineteenth century. Aron Nimzowitsch, in My System (1925), expanded and systematised them. The elements most commonly cited are:
Material
The sum of the pieces each side has. The conventional values are pawn 1, knight 3, bishop 3, rook 5, queen 9. The king is not assigned a value because it cannot be exchanged. These numbers are approximate and position-dependent: two bishops are often worth more than their sum, a bishop is frequently stronger than a knight in open positions, and a rook on an open file may be worth more than the conventional figure suggests.
King safety
A king in the open, or with a weakened pawn shelter, is a permanent liability. Before committing to any plan both kings should be assessed. A plan that exposes one's own king is rarely correct.
Piece activity
A well-placed piece controls more squares and has more options than a badly placed piece. A knight on a strong outpost may be worth more than a passive bishop locked behind its own pawns.
Space
The number of squares a player controls, particularly in enemy territory. A space advantage gives pieces more room to manoeuvre and can cramp the opposing side into passivity.
Pawn structure
Pawns cannot retreat. Every pawn move is permanent. The structure of the pawns determines which files and diagonals are open, where pieces belong, and where weaknesses are fixed. Pawn structure is treated at length in the next chapter.
Weak and strong squares
A square that cannot be defended by a pawn is a potential outpost for the opponent. A pawn that cannot advance, and the square in front of it, is a recurrent target of piece pressure.
The initiative
The side whose moves create threats forces the other side to respond. Maintaining the initiative allows a player to dictate the course of the game. Surrendering it means playing reactively.
A good plan improves the worst-placed piece, fixes a weakness, or contests an important square — ideally all three at once.
