Restriction
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 restricted position is one where the opponent can still move, but nearly every move makes something worse. Restriction is the craft of getting there, and it is quieter than an attack. You take away pawn breaks first, because a freeing advance such as ...c5 or ...f5 is how a cramped side usually starts to breathe. Then you cover the squares their pieces want, so a knight finds no outpost and a bishop finds no open diagonal.
To recognize it, count the safe moves your opponent really has. If most of their pieces are tied to defense and each pawn push drops a pawn or concedes a key square, the restriction is working. Often a small space advantage, a well-placed knight and one pawn that controls a break square are all it takes.
The method fails when you forget your own king and your own tempo. A restrictive setup that allows one clean pawn break can collapse in a single move, and if you react passively to that break the initiative changes hands. Before committing, ask which single pawn move would free the opponent, and arrange your pieces so that move is already met. Then improve slowly. A restricted opponent will often self-destruct if you simply refuse to hurry.
Compare it with Bind. A bind is a lasting space edge in which advanced pawns, backed by pieces, control the squares the opponent needs and prevent their freeing pawn break, leaving their army cramped.
A neighboring idea is Clamp. A clamp is a bind created by pawns, typically two pawns on the fourth rank, that takes away key squares and stops the opponent's freeing pawn break, leaving their position permanently short of space.
A neighboring idea is Prophylaxis. Prophylaxis is the strategic habit of spotting what your opponent wants to do next and making a move that quietly prevents it, giving up some of your own initiative to remove their best plan.
Where "Restriction" fits your own play is easier to judge with a coach reading your games; the first lesson is a paid one-on-one review that ends in a written plan.

Domination is a plan in which your pieces and pawns watch every exit of one enemy piece, so that it can neither move safely nor contribute, and it may even be lost.
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.
