=== Sekinin barai for suukantsu ===
Uncommonly found in rule sets, sekinin barai may be invoked on the player discarding into a fourth kantsu of a [[suukantsu]] hand. Due to the criteria for recognizing sekinin barai, the fourth kan will always be a daiminkan.
Uncommonly found in rule sets, sekinin barai may be invoked on the player discarding into a fourth kantsu of a [[suukantsu]] hand: when there's a hand with 3 existed kantsu ([[sankantsu]]) and the player claimed the fourth kan, the feeder of fourth kan becomes liable.

: Shimocha becomes liable for the fact that he completed an ensured suukantsu with his discard.
 
Due to the criteria for recognizing sekinin barai, the precedential three kans must already exist, and the fourth kan will always be a daiminkan.

: Toimen doesn't become liable, his melding doesn't confirm a suukantsu, even with a possibility of hatsu kan afterwards. <ref>
Tenhou used to suggest [http://tenhou.net/0/?log=20070224gm-000b-0000-6388336d&tw=3&ts=5 such controversal liability relationship] in early years. This rule was soon deprecated after then.

: Kamicha doesn't become liable, suukantsu is not completed yet at the moment when he discarded 2-pin. It was a pon of 2-pin and the hand is only a sankantsu, even though an added kan of 2-pin happens afterwards.
 
Though such pao rule is not commonly used, as the fact that it is hard for opponents to figure out which tile exactly was needed to complete suukantsu. That being said, even though they clearly know they should prevent to complete a fourth kan by avoiding discarding raw unpaired tiles, this may still mean a plenty of choices which is hard to figure out, unlike the other yakumans which usually have a cleared choice of alternative tiles.
