Weird spot. The problem with passive players like this is that a lot of them are so bad at hand-reading that it's hard to rule out them raising a hand like A9 or something for value here. They don't bluff with air hands, but they over-value made hands.

I doubt you can ever fold the flop given the odds you're getting, and while I do think there's a reasonable chance you're behind right now, the turn betsizing doesn't really strike me as a monster hand too often, and since they're giving you better than 4 to 1 on a call, I think we can justify peeling this turn bet with the plan to fold to further aggression on the river. I think we find ourselves in a spot where if villain is betting worse for value, he/she checks back almost all rivers and we win, whereas if they have better than TT, they're very likely to continue betting, and we can fairly comfortably fold.

If villain had bombed turn for 1100 I might have thought about folding occasionally, but I think peeling to re-evaluate is fine getting 4 to 1.
