Quiet move
A quiet move is a move that makes no capture and gives no check, yet creates a decisive threat or removes the opponent's last defense, so it is easy to overlook among more forcing moves.
Most tactics are built from checks, captures and threats, so those are the moves you look at first. A quiet move does none of that. It changes the position just enough that the opponent has no good answer, for example by taking away an escape square, adding an attacker, or preparing a mate that cannot be stopped.
Quiet moves matter because they are often the only winning move. A direct check can let the king run away, while a patient move first removes the escape squares and then the check finishes the job. They also appear in defense, where a calm move stops the opponent's idea before it starts.
To find one, ask what the opponent can still do after your forcing moves run out. List the squares the enemy king could use, the pieces that guard the key square, and the moves that would give them luft or a defender. Then look for a move that covers one of those squares or cuts one of those defenders, even if it threatens nothing on its own. To defend against quiet moves, try the same question from your opponent's side: if it were their turn, what would they play?
In the diagram White to move plays Bc4. Nothing is captured and nobody is checked, but the bishop covers g8, and the white king already covers g7 and g6. Black's only legal move is Kh7, and then Rh1 is checkmate. If White hurries with Rh1+ at once, the king simply steps to g8 and the mate is gone.
A neighboring idea is Brilliant move. A brilliant move is a label some analysis tools give to a strong, hard-to-find move, often a sacrifice, that the engine confirms keeps or improves the position despite looking risky.
Compare it with Greek gift sacrifice. The Greek gift sacrifice is a bishop sacrifice on h7, or h2 for Black, played as Bxh7+ Kxh7, followed by a knight check on g5 and the queen coming to the h-file to attack the exposed king.
Compare it with Zwischenzug. A zwischenzug, German for in-between move, interrupts a sequence both sides expect: instead of recapturing or answering a threat at once, a player slips in a check or bigger threat first.

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.
A combination is a forcing sequence of moves, usually built from sacrifices and checks, in which every move leaves the opponent few or no choices and the sequence ends in a concrete gain such as mate or material.
A mating net is a setup in which the enemy king is surrounded by attackers and its own pieces so tightly that checkmate cannot be avoided, even if the final blow is a move or two away.
Zugzwang is the bind of having to move when standing still would be best: the player on move has only moves that weaken the position, and since passing is not allowed, the duty to move itself costs something.
