2/4 200BB deep JJ makes set

[2218]

Just wondering what you guys think about this hand...

CO ($800+ and 19/12, not a great player) open raises $16. Fold to me on the BB ($712). I repop to 50 with JJ. He 4-bets to 124. I call.

Flop comes JT8 rainbow. Check check.

Turn is 7. I lead 166. He calls.

River is K. I push...
