I'd put him on big aces, pairs and bluffs. I think it's unlikely the turn and river changed anything. Your pot odds
to call aren't awesome so you could easily wait for another hand. I'd want something that could beat a few of his value hands. TT or better.
My odds to call aren't super, that's true, but they're not much worse than a normal pot-sized bet. I am getting 1.87:1 as opposed to the normal 2:1, a difference that amounts to 1.5% more equity needed to call. After rake and everything, I figured out that we need to win 36.8% of the time to call here (we need 35.1% after rake for a pot-sized bet).
In a vacuum, his bets are badly sized. Now, I do occasionally over-bet the flop when stacks are deep, and I want to get stacks in. An over-bet on the flop (8/5 pot), pot turn, and 3/4 pot bet would get us all-in on the river. That's less threatening than pot, pot, 6/5 pot. If we're getting all-in, there's going to have to be an over-bet or a raise at some point in the hand. Sure, we're over-betting by a larger percentage in the first scenario, but it's a smaller absolute bet and smaller relative to the remaining stacks. So, it's easier for a player to find the call button. Typically, I need a history with a player to do this.
Frankly, if he had bet pot (or close to it) on the turn, I would have been forced to fold anything but a monster. When he checks the turn, I think his range of monsters narrows a lot. That's not to say his range isn't strong or that he doesn't have a good hand. I just feel it makes very-strong hands (99, 66, 88) less likely. Of course, this is 10nl and anything is possible.
