Hand from TS 6m

[EverettKings]

He can't possibly be a good player and play any hand like this besides some very very fancy bluff. Good players will bet most of their big hands on that flop, won't bet so tiny on the turn with a good hand or a bluff, etc etc.

OK, so now that we know he's not a good player, it's a clear fold. Definitely a slowplay (or he turned big). Never a bluff, a value bet from a worse hand, or a semibluff.

So, muck.
