Lost in the river with trips

[KSakuraba]

Ive been pretty much running the table over with a hot run of cards and shown only premium hands (AA twice, KK twice, AKs for a nut flush, etc,etc) during my one hour perioid at the table. Not once have i been caught bluffing, even though i have bought a few pots with total air. Villain in this one is pretty weak-tigh for what ive seen, has given up many pots when faced resistance after his preflop-raise, so i thought this would be a good place to take the pot if any danger showed on the board. But the river had other things in mind.

(Thought a bit about check-folding here but decided to stick with the plan A with so many draws on the board, pretty much put villain on Kx or PP at this point)

Sakuraba pushes... (villain has ~350 left)

I though a while to just calling here but am i not missing value from AK, AA or some weird two pair? Should i raise smaller to just value bet? I thought this kind of overbet would scream BLUFF so Kx could call even more easily this than some miniraise. Am i way off here?
Any comments on any streets greatly appreciated.

Thanks guys.

I raise smaller on river. I think you're all in will scare off AA, AK, etc.

Also, I'm sure you've heard this before, the rake in the EUR games is OUTRAGEOUS. I know you probably think the players and game make it worth it, but i can't imagine its so.
Just play dollar game equivalent to 2/4 EUR and pay half the rake.
