villain is a good reg, but kinda aggro tard
3bets 35% and cbetting 90% in 3bet pots
he doesnt value bet really thin in 3bet pots, his range when he c/c the flop is likely to be showdown value ( prob A9, K9 and other marginal SD hands )

good spot to be overbetting here ?

either overbet like 690 or bet 176 to induce turn-into-bluff spews

I dont see why you would expect him to raise here. i bet pretty big here, near pot

I thought about betting small to induce, but I think his whole range here is going to call instead of turning it into a bluff

You are so deep I think there's no need to bet small to induce bluffs from him if he has any in his range. I would go for potsize-ish bet here on the river.

why no overbet ?
as he checked to me on the flop I have all my range(call vs 3bet range) to decide if I want to bluff, I feel like it's a good spot to put a lot of pressure on him and I think I would be bluffing him a lot, also I think if I overbet it's more likely that he hero calls(or not?) with a hand like 78 or 77, because if I overbet it's unlikely that I'm valuebetting too thin like A9 or TT, so im basically with bluffs and flushes ( and sets maybe ) repping a really narrow range where he's capped

but dont know if he's smart enough to think this way
