While chanta can be seen as the converse of [[tanyao]], chanta is much slower. This is because the simple tiles are more [[tile efficiency|efficient]] for hand development. This can be measured by [[Ukeire|tile acceptance]] - the more tiles that can be used to form a sequence/pair/triplet, the higher the tile acceptance, and the more efficient the tile (generally) is. | While chanta can be seen as the converse of [[tanyao]], chanta is much slower.

As displayed above, forcing yourself to honors and terminals greatly reduces acceptance. | As displayed above, forcing yourself to honors and terminals greatly reduces acceptance. Also, chanta cannot take advantage of ryanmen waits. It can accept ryanmen {23} and {78}, but 1/2 of the waiting tiles (4 or 6, respectively) ruin chanta. Since chanta cannot accept ryanmen, and ryanmen is 2x faster than the other basic waits, chanta means losing out on a lot of speed. Plus, once you get into tenpai, chanta is only guaranteed with a bad wait hand (<= 4 tiles in the wall). | ||
Overall, since chanta is so slow, and only worth 2 han, it usually isn't worth the effort. Even without considering [[riichi]], there are easier ways to get 2 han, such as tanyao + [[pinfu]], pinfu + 1 dora, pinfu + [[iipeikou]], and so on. Therefore, players will rarely go for chanta.
