Menzenchin tsumohou: Difference between revisions

'''Menzenchin tsumohou''' {{kana|門前清自摸和}}, otherwise referred as '''menzen tsumo''' or even simpler '''tsumo''' {{kana|ツモ}}, is a [[yaku]] obtained when a [[naki|closed]] hand wins with a self-drawn tile. Therefore, this yaku cannot be scored if a tile was [[naki|called]] from another player or if the hand wins from another player's discard.

All closed hands can qualify for menzen tsumo; declaring [[riichi]] is not required. A hand can win even if its only yaku is menzen tsumo. No open hand may score this yaku - the instant a player [[Naki|calls on a discarded tile]], this yaku is invalidated.

This yaku is typically accompanied with riichi.  Of course, the [[riichi strategy|use of riichi]] will depend on the current state of the game: current point standing, other player riichi calls, potentially threatening hands, tile waits, and tile availability. Sometimes, it can be better to stay in [[damaten]] rather than riichi.
