I'd really like to hear what you think is so interesting about this. Is turn min-bet blocking? I doubt that could be very successful at the 215s, although at the 11s I think that may actually work. Is turn min-bet an attempt to encourage a raise? That sounds like it may be reasonable on some boards, but the flop now has a heart draw and a straight draw out, so unless he has Ah5h, I don't like it here, and even then, another shot of 135 looks pretty weak.

My diagnosis is that it's likely he A) is very unfamiliar with poker and his bet amounts on the other two streets just happened to be normal or B) meant to bet a different amount.
