The main purpose of tile calls are to push hands forward and reduce the number of [[shanten]]. However, kuikae doesn't reduce the number of shanten, as the tile to discard can make a group with the tiles used for calling to form a [[mentsu]]. This kind of behaviour is usually not recognized to be "meaningful" to the player himself/herself, but as a way to "disturb" other players, e.g. utilizing kuikae on purpose to eliminate [[ippatsu]] or [[Haitei raoyue and houtei raoyui|haitei]]. More and more people agree with it and then the kuikae rule becomes popular today. | |||
Note that kuikae is not always meaningless to the player himself/herself. The use of kuikae often includes: | |||
# Skipping a chance to draw to prevent drawing a dangerous tile near the end of a [[Kyoku|round]], especially when in [[tenpai]], due to the [[Tenpai#Ryuukyoku|noten penalty]]. | |||
# Changing the end of a shuntsu (as shown in Example 1) to obtain yaku, especially [[tanyao]], [[Sanshoku doujun|sanshoku]], [[chanta]], [[Ikkitsuukan|ittsu]], etc. | |||
Some rulesets only forbid discarding the called tile, but allow discarding the other end tile of a chii (e.g. [[Japan Professional Mahjong League|JPML A]]), therefore it sometimes can be a useful strategy. | |||
