When a riichi declarer holds three identical tiles and draws the fourth after the riichi announcement, he may form an [[Kan|ankan]] from these tiles instead of discarding the fourth. The hand composition and the possible winning tiles may not change: It is not allowed to declare kan if, for some possible winning tile, any of the three identical tiles may be interpreted as part of a shuntsu or part of the pair.
When a riichi declarer holds three identical tiles and draws the fourth after the riichi announcement, he may form an [[Kan|ankan]] from these tiles instead of discarding the fourth. The hand composition and the possible winning tiles may not change: it is not allowed to declare kan if, for some possible winning tile, any of the three identical tiles may be interpreted as part of a [[shuntsu|sequence]] or part of the pair.
 
'''Illegal example:'''
:{{#mjt:3444m 778899s 333z}}, draw: {{#mjt:4m}}
 
It is not allowed to kan the fours. The manzu tiles may either be interpreted as a 3-4 [[Ryanmen|ryanmen]] wait and a 4-4 pair, or as a 4-man ankou with a 3-man tanki wait. For a legal kan declaration, the three identical tiles would have to be an ankou in any interpretation. Had the player drawn a west wind, he would have been allowed to kan it.
 
'''Legal example:'''
:{{#mjt:111m222333p5678s}}, draw: {{#mjt:1m}}, {{#mjt:2p}}, or {{#mjt:3p}}
 
For any improper kan call after a riichi, the hand is subject to [[chombo]], even at [[ryuukyoku]] or the hand wins via [[rinshan]].
