200nl: KK - is he trying to stack-a-donk?

[igetjokes]

Villain is 35/8/1.6, standard Party fish. His weak flop lead/call then turn check makes me feel he's trying to stack a donk (CRAI turn, usually with set).

Final Pot: $267.55

If I was deeper I could bet/fold turn, but stacks are short enough on turn that a bet basically prices me in to call a shove as either a CRAI turn or open shove on river.

Comments on all streets please, I'd like to hear some alternate lines etc too.
