TPTK oop against a manaic

[johnnybeef]

This table was a beaut. Two guys over 50 vpip on my direct right and left. The villain in question is one of them at something like 70/20/8 over 20 hands. I had been very solid up to this point which may or may not be a consideration because he may not be on the 1st level.

The way I see it, this hand boils down to how often villain bets weaker hands for value/bluffs. As such, one word answers are highly encouraged despite what the awful moderation in this forum encourage.

I call because he is a complete maniac like your title says. He could think K4 is the nuts here especially since in his mind, a river check = weakness. Im more tempted to b/c here than anything else but I understand why you would c/c.

I hate this spot, I would be much happier if he a guy with these stats had come over the top on the flop or turn.

I call but I am not smiling. Any reads on how he plays his big hands?
