An irrelevant move is a move that cannot change the [[opponent]] strategy. It is considered as a waste of time and has to be avoided. The most obvious irrelevant move one can play is playing in a [[useless triangle]].

 A move that does not interfere with any of the opponent's threats is also irrelevant.
-An irrelevant move that is also a [[forcing move]] can sometimes be used to manage the game clock. If the time controls include an increment (for example 10 minutes/+30 seconds per move), then a player who is low on time could make an irrelevant move that forces a response in order to get more time on their clock without changing the game situation. This is risky, though, as the opponent could potentially find a better response.
+An irrelevant move that is also [[forcing move|forcing]] can sometimes be used as a [[time tesuji]], i.e., a move that is played to manage the game clock.

 A move in a cell that is [[captured cell|captured]] by the opponent is also an irrelevant move, but sometimes the opponent is forced to respond to maintain the capture. While such a move does not improve the position of the player who makes it, it can sometimes happen that it does not improve the opponent's position either. Thus, the effect of such a move is in the best case neutral for the player who makes it. However, if the opponent has a better response available, such a move can still hurt the player who makes it.
-Any move that the opponent can [[dead cell|kill]] with the next move is also irrelevant, as it only helps the opponent and doesn't help the player.

+Any move in a [[dead cell]] is irrelevant. An example of this is the [[useless triangle]]. If a player plays in a dead cell, the opponent does not have to respond, i.e., the situation is as if the player had passed.
