Closed game
In a closed game, locked pawn chains and blocked central files restrict the pieces, so maneuvering and pawn breaks matter more than quick tactics and direct attacks.
When the center is locked, the board feels smaller. Pawns stand head to head, the long diagonals are shut, and there is rarely a forcing line to calculate. The game becomes a contest of plans: where can I place my pieces, and which break can I prepare that the opponent cannot stop?
Knights tend to improve in these structures, because they can jump over the pawns and settle on advanced squares that bishops cannot reach. A bishop biting on its own pawn chain is a typical weakness. The side with more space can have trouble if its own pieces have little room, so exchanging a few pieces to relieve the tension is often wise.
Closed does not mean slow or drawish. Pawn storms on the wing where you have more space can be fierce, since the opponent's pieces may be unable to cross to defend. The usual rhythm is to build up behind the pawns, wait until your pieces are optimally placed, and then strike with the break.
A helpful rule for club players is to identify which pawn lever each side can eventually play. If your opponent has a break and you do not, start looking for a counter-plan right away rather than shuffling pieces.
Compare it with Semi-open game. A semi-open game starts with White's king pawn advancing two squares and Black declining to mirror it, choosing a defense such as the Sicilian, French or Caro-Kann with an uneven pawn structure.
It sits close to Flank attack. A flank attack is an offensive on a wing, typically by pawn advances supported by pieces, and is best launched when the center is closed or stable so the opponent cannot answer with a strike in the middle.
It sits close to Open game. An open game is a position or opening in which the central pawns have been exchanged or are absent, leaving open files and diagonals where pieces move freely and tactics and quick development decide.
Strategic ideas such as "Closed game" show up in your games as small decisions, move after move. A first lesson with George Li reviews those decisions and turns them into a study plan.

A pawn chain is a string of friendly pawns on a diagonal, each guarded by the pawn behind it, so only the rearmost pawn, the base, lacks pawn protection and becomes the usual target.
A space advantage means controlling more squares, usually through advanced pawns, so that your pieces have room to maneuver while the opponent has little room and finds it hard to exchange or regroup.
Restriction is a strategic technique of limiting the opponent's useful moves, pawn breaks and piece routes so their position has few constructive options, often by controlling key squares rather than winning material.
A blockade is the plan of stopping an enemy pawn by occupying the square it must move to next, most often a passed or isolated pawn, with a piece that stays safe and useful there.
A pawn break is a pawn move that makes contact with an enemy pawn or chain, forcing an exchange that changes the structure and gives your pieces new files or diagonals to use.
An open game is a position or opening in which the central pawns have been exchanged or are absent, leaving open files and diagonals where pieces move freely and tactics and quick development decide.
