Menzenchin tsumohou 「門前清自摸和」, otherwise referred as menzen tsumo or even simpler tsumo 「ツモ」, is a yaku involving closed hands. With a tenpai hand, a player attains this yaku by winning with a drawn tile.
Formation
With this yaku, all closed hands qualify for menzen tsumo. In fact, a closed hand may instantly win by self draw, even when it is the only yaku for the hand.
No open hand may qualify for this yaku. The instant a player calls on a discarded tile, then the player forfeits the right to declare this yaku until the next hand. The same applies to riichi.
Compatibility
^ Ippatsu requires riichi to be of any use.

Mentsumo with toitoi is actually the yakuman, suuankou. Otherwise, this yaku is compatible with all yaku except for houtei and chankan. Neither of those two yaku can win by self-draw.
With riichi
This yaku is typically accompanied with riichi. Of course, the use of riichi is only advisable on the current state of the game: current point standing, other player riichi calls, potentially threatening hands, tile waits, and tile availability. At times, it may simply be advisable to utilize damaten, rather than putting one self at risk.
