noun
discarding somewhat safe tiles while still aiming to win
Mahjong term. A defensive strategy where a player discards tiles that are relatively safe (less likely to deal into an opponent's hand) but still keeps their own hand ready to win. It balances offense and defense.
回し打ちは、降りるほどではないが安全牌だけを切る戦略だ。
Mawashi-uchi is a strategy of discarding only safe tiles, though not as defensive as completely folding.
彼は回し打ちで、危険な牌を避けつつテンパイを維持した。
He used mawashi-uchi to avoid dangerous tiles while keeping his hand tenpai.
Compound of 回し (mawashi, 'rotating' or 'circulating') and 打ち (uchi, 'discarding' in mahjong context). The term likely refers to the idea of 'circulating' safe tiles while keeping one's hand alive.
