The major disadvantage to shanpon involves locked tiles.  In this case, pairs of waiting tiles may be incorporated into other player(s) waiting hands, which may or may not be dropped.

Shanpon 「双ポン」 is a wait pattern involving two groups of paired tiles, where either is looking to complete a triplet.

Pattern

Waiting for: or

Fu

A shanpon wait does not generate fu by itself. However, the triplet formed by a shanpon wait is worth fu.

  • A triplet is worth 4 base fu.
  • Fu is doubled if the triplet is composed of honor tiles or terminals.
  • Fu is halved if the triplet is open (if the triplet is completed by ron, it is considered open.)

Usage

Shanpon is considered a "bad wait", because it only waits for a maximum of 4 tiles of two tile types (2 tiles/type). Like the other bad waits, shanpon is immune to suji. Thus, it can be used for suji traps. Shanpon (along with tanki) can also incorporate honor tiles, which may be perceived as safer. Players looking to defend may fall to a shanpon wait more easily.

If all 4 winning tiles are still available, all else equal, a shanpon wait is considered better than the other basic bad waits (those being kanchan, penchan, and tanki).

  • During tenpai, shanpon waits for two types of tile, while the other only wait on one type of tile. Waiting on two different types of tile is generally better.
  • Before tenpai, a shanpon wait - if both pairs are made from middle number tiles - has more available upgrades into ryanmen.

However, because there are only 2 available tiles per type, it is easy for the tiles in a shanpon wait to be "used up". One or both types of tile may be incorporated into other players' hands (as either a pair or part of a sequence), thus limiting the wait.

Combinations

Shanpon may combine with other tile waits. Shanpon with ryanmen produces entotsu. This combination may be increased with ryanmenten. Shanpon has the ability to mix with itself. This is only possible with a built-in pattern of iipeikou, plus a fourth numbered pair in the sequence.
