Waits & Tenpai
Closed wait
Also called: Kanchan, 嵌張, 坎張
Waiting on the middle tile of a chow — e.g. waiting on 4 to complete 3-?-5.
A closed wait (kanchan in Japanese, 坎張 in MCR) is when you're waiting on the middle of a 3-tile chow. You have the two outer tiles and need the middle one — e.g., 3p and 5p waiting on 4p. Like edge waits, it's a one-side wait, so it scores a bonus in Riichi (2 fu) and MCR (closed wait = 1 fan).
