noun
one's turn (in go, shogi, etc.)
Primarily used in board games like go and shogi to indicate whose turn it is to move. Can also be used more broadly for taking turns in other contexts, but the gaming nuance is strong.
将棋では、手番が回ってきたらすぐに指すべきだ。
In shogi, you should move as soon as it's your turn.
囲碁の対局で、手番を間違えてしまった。
I made a mistake about whose turn it was in the go match.
