Weak 4th street check?

Beer, Where do I start??? Limp raising here shouldn't even cross your mind!! Once the 4 completes and 3 callers in front of you now the hand is just a call, because when a small card completes his most likely hand here is a big pair better than jacks.

4th Street you probably should bet and hope the guy with the 4 raises to thin the field.

5th street is an odd bet, now I think i'd prefer to check, jacks just aren't that great right now with so many players.

I like 6th good check raise. The river is also fine.
