Strange hand, losing ton of value?

[orangeman]

BTN is total sicko fish 38/4/0.63
I saw him making stupid calls, but never saw him play river like this...Im completely lost in that spot, especially bcz we was 200bbs deep,

Here`s my thoughts, I know for sure he could call me with KJ, and hell even 23o.
I know for sure he would raise flop if he hit good(set, 2p etc), and he`s 100% bets turn if he has same, so when he pops the river i got completely lost.
And one more thing, i knew if i push here and he show`s me KJ or 23 this will put me on SICK TILT...
