Ok so I had just won this pot where I had played Aces kinda sneakily, flatting a raise preflop, flatting a bet on the flop, checking the turn and getting paid off on the river. I haven't open raised for a good hour, and I would think my image is kind of passive because I had been playing a fair amount of pots, and repeatedly flopping air.
Anyhoo, I raise

in mid position at 150/300 to 800, and get 3 bet by the button to 2200. He'd been fairly active and quite aggressive, but selectively so.
I started the hand with 37k, he started it with about 30k.
I opt to call, which I think is fine even though we're out of position?
Flop comes down

. I check, he bets small, about 2700. I call.
Turn is the

. I check, he checks behind.
River is the

, putting 4 to a straight on the board. The

would have been a nicer card! I lead out for about 4k. He thinks for about a minute, and moves all in for 26k ish.
I tank and end up folding. In reflection I think the hand plays out kind of standardly, but I think the fact there are 4 cards to a straight on the river makes it kind of interesting, and also his check on the turn is confusing if he has us beat.
