Pre-moves on Chess.com

Pre-moving is when you make your move before your opponent takes their turn, commonly used in fast-paced games like Bullet and Blitz.

When pre-moves are enabled, you can make a move during your opponent's turn that will automatically be played as soon as it's your turn. Simply move the piece as if it were your turn, and the move will be highlighted in red on the board:

In the above picture, Black's move, d5, is highlighted in yellow. Black then made a pre-move, which is highlighted in red, Nc6. The knight move isn't on the board yet but will play automatically as soon as White moves, no matter what White does! For example, if White captures the pawn with exd5, Nc6 would be a very bad move!

Guidelines

Guideline	Details
Automatic Play	The pre-move will automatically play even if your opponent makes an unexpected move, which could result in a blunder.
Undoing a Pre-Move	To undo a pre-move, simply right-click or tap on the pre-moved piece.
Timing	Pre-moves are executed almost instantly, using only 0.1 seconds of your remaining time.
Illegal Pre-Moves	If your opponent's move makes your pre-move illegal, such as putting your king in check, your pre-move will be canceled, and you'll need to make a different move.
Multiple Pre-Moves	You can make up to five pre-moves during your opponent's turn. They will be played in the order you made them, subject to the limitations described above.
