Chankan (搶槓) is a standard yaku. It is dependent on the usage of kan, where a player may declare ron while a player calls to upgrade a minkou to a shominkan. In other words, if a player is tenpai for a tile used for an "added kan", then the player may declare a win on that tile. In most cases you are not allowed to call ron on an ankan. The exception to this is when you are in kokushi tenpai and another player's ankan is your wait.

Machi

As defined, chankan can only be achieved when a minkou (open triplet) is upgraded to a shouminkan. In other words, another player had called pon earlier and then drew the 4th tile, to be called kan with. If a player is tenpai for that tile, then the player may declare ron.

So, when it comes to machi (wait patterns), only three basic types can be used for chankan: penchan, kanchan, and ryanmen. Some patterns that utilize any of these three may also apply. This is simply due to the number of tiles remaining (just one), for every minkou.
