My two plays I would like critiqued are the turn bet of 22 RMB and the river call.

Villain is a 30 something Australian player who bluffs with a very high frequency, and was stuck around ￥1000 RMB at the time of this hand.

Do you think my small turn bet was a big mistake, small mistake, or non-mistake, and was my call reasonable despite the turn where all the straights and flushes got there?

Sorry I can't post a real hand history, as none of the sites I play at support HM2 or PT4 so I don't have either of those programs.
