Nevertheless, unlike daisangen and daisuushi, the tile that determines suukantsu is not self-evident. It is difficult for an opponent to know which tile would complete the 4th kan. While a player may know which tiles 100% cannot be a kan, which tile exactly is uncertain. Based on the above reasons, the pao rule is not commonly used for suukantsu. | Nevertheless, unlike daisangen and daisuushi, the tile that determines suukantsu is not self-evident.

Sekinin barai exists to punish "foolish" discards that ensure a yakuman. | |||
However, when the last group of a yakuman is called for an open [[kan]], the discarder is still liable for pao. Even though the yakuman already existed without needing the kan, pao is still applied. | |||
To explain how liability works in terms of "the player is responsible for ensuring a yakuman", it is better to switch to the opponent's point of view. When a yakuman-holder has called for two groups of dragons, daisangen is not guaranteed ''in the opponent's eyes''. Once an opponent discards the third dragon, and it is called for a kan, daisangen becomes guaranteed ''in the opponent's eyes''. So, when discarding a tile used for a kan, pao is still invoked: from the opponent's point of view, daisangen goes from not guaranteed -> guaranteed. | To explain how liability works in terms of "the player is responsible for ensuring a yakuman", it is better to switch to the opponent's point of view.
