Stars 25-50 villain has 4k stack i cover

Villain limps utg, i raise with ajdd in mid position. Four total callers.

Flop js 6d 4d, villain checks i bet out 550 into 750 pots, two other players fold villain flat calls. Turn k of clubs...

Villain checks with 3500 behind and pot of 1800. What is my line?

no read on villain other than he was a short stack artist and i tried to bluff him with absolute air in another pot
