AJ vs I dont even know what to call him

[winky51]

Bad dude has no clue on pot odds, calls raises with any paint, is tricky. Has made some bad calls and is now at $3400 chips. only 20 hands into tournament.

5 limpers, I am BUT with AcJd

Flop comes Js 6d 2h POT 160

5 checks, I bet 120, 4 folds CO calls 120.

Turn comes Js 6d 2h Td POT 400

CO bets 150, I call.
I am starting to think this guy has a set considering how many limpers and that he called a large flop bet.

River comes Js 6d 2h Td As POT 700

CO pushs putting me all in for 1250, Hero?
