Penchans are generally considered to be a bad shape, or unfavorable pattern. The limit stems from the need of only one tile type for completion. This limitation renders the pattern difficult for [[tile efficiency|tile development]]. For a 1-2 penchan, the 4 of the same suit is a useful tile, on which the 1 may be discarded. A 2-4 shape can be completed with only one tile still, but it can be turned into the [[ryanmen]] 4-5 by drawing the 5 and discarding the 2, if necessary. In short, penchan offers a limited ability to alter the wait pattern, if a need arises, especially for a case of [[karaten]], when all four tile types are not available. | Penchans are generally considered to be a bad shape, or unfavorable pattern.
