I would probably just limp on third street. You're really not particularly strong in either direction.

Fourth is a fold. The Jack is a terrible card. You should be well behind in both directions, and the pot is small. Calling in spots like this can lead to compounding mistakes later in the hand.

Checking on fifth was fine. I would do so with the intention of folding.

I think I check sixth as well. The guy with the Ace in the door continued to lead when he caught the Nine on fourth, so that looks like a big pair, probably bigger than Jacks. He may have gotten skeered and checked on fourth after it looked like the low got there. I'm guessing you have the best low draw, but you only have one card to catch. I would check and hope.

The pot is plenty big enough that you have to pay off on the end, but I wouldn't like it.
