I think this is fine until river, sizing is ok on turn but we could go a little bigger. Depends how often you want to bluff, I guess. River, I would want to b/f here for value, but since this guy just sat down, I probably just c/c. With better reads I could make a better judgment on if I should b/f or b/c river, but without that knowledge I'd take the cheap showdown to avoid a tricky decision. He's surely more likely to bluff when we check river, so it seems like a safe default, if not the most +ev. It also discourages him from bluffing us on future rivers, and may even induce a loose call when we next value bet river against him.

River bet does indeed suck unless you're trying to induce a bluff, but you have no reads on this guy and he has none on you, so if I were to bet, I'd keep it regular and make a standard above half pot vbet.

As played, I know I'm calling this raise, and I know I'm losing to a flush or A7s/78s. I could fold if I bet the river properly, if we showed genuine strength and still got raised.
