The [[ippatsu]] yaku is normally interrupted by a kan call.  To call chankan, the opposing player had already called for kan.  However, ippatsu is still not interrupted because the whole kan process has not been completed.  The entire kan process includes the kan call itself, plus the rinshan draw and the discard afterwards.  The chankan win occurs in the middle of that process.  So, it is allowable to score both ippatsu and chankan at the same time.

=== Rinshan kaihou ===
Given the procedure for kan, the chankan takes precedence over [[rinshan kaihou]].  Here, the call for a chankan win denies even the drawing of the rinshan tile.  Therefore, even the chance for rinshan kaihou is denied.
