Is the villain ever doing this with a flush? I would only expect this from either a very LAG or very passive 'all in w/nuts only' player

on the other hand, how does he minbet/call a made hand then push?

so what is this then? AsKx? How does your answer change against a smart opponent?

this is a pretty standard fold.

I would bet a little more on the turn though.

Standard fold, def, b/c there's I can't even beat any other Kings. But how do you rate his hand? is this always a flush?
