OK I couldn't decide to ask what your move is on the flop or just include everything.. so I just included everything.

I can't remember their stats nor do I care to look, but they were both bad vpips over 40 and call down with a lot of shit hands. What is wrong with this hand? Was the flop lead bad? Calling the min-raise bad? I have to be almost certain someone at least has the A here... right? Anyone see any major flaws I could improve here?

If MP isn't behind me does anyone ever consider calling this river?

I think I just 3-bet all-in on the flop and gamble with them.

The min-raise and cold call doesn't scare Henry?
