HU 25/50 really interesting spot in big pot

[gordo16]

Liraerik and I had been playing HU for quite a while before this hand came up. I had been playing unusally conservative for myself and had won a lot of 70/30 and 60/40 pushes on the flop where he would 3bet preflop and then continue bet on boards like 557 with dry overpairs and I would push with wrap draws, flush draws, etc.. We have a little bit of history HU but only 4k hands or so. Anyways, in this hand, I decided to make a rare 3bet for the session and then played it rather strangely... He tends to take control when I check to him after 3betting, so I decided to play the hand slow. Let me know what you think of my play up until the river, and what you think my action should be after the river card hits. Thanks.
