JJ rivered set how much to raise?

[foldem]

2/4 6max
me 650
opponent covers

I raise JJ UTG+1 to 15, BB calls. BB is kind of LAG he reraised a minraise with 55 preflop. Flop comes 2 4 9r. He checks I bet 30, he calls. Turn is 7x, check, check.
River is a J he leads for 45 into a 90 dollar pot. How much should I raise? I have 600 behind and he covers.

It's very unlikely that he's made a strong hand I would raise sometihing that looks like you have K-high and can't call the river bet. I'd raise to $100 and hope he raises back.

200$ looks good
