I agree that the 3-bet is probably unwarranted and not the most profitable line to take. I do think we have more implied odds than betgo and ansky are leading on here because the guy is a bad player. He friggin' block bet the river with a 4-card straight out there with TPMK against the rock of all rocks. I think we're busting the guy if we bet smart if a club hits on the turn (and we don't get an action killer on the river... but even then, he'll probably block/call with his KTo).

While gobbo was joking, I think, it's true that your life equity is highest by gambling in this spot and then crushing the nearby NL game or building your stack as a 60/40 dog. If you remove other games as part of your equity, then I think the best line is to call his raise, and either call/fold the turn depending on his action and the card.
