[5nl] QJs...very strange hand.

I think it is really difficult to interpret, and it is hard to deduct the line of thought of some fishes without reads, but mostly, translate his minbets into "checks". So he pretty much check raises turn and river.

He could have pretty much have anything you mentioned, and also a straight and bluffs. You played it OK, make a note of what he had for future reference and some insight into his foggy brain.

T's full or some complete nonsense.

Either way I think you can probably flat the river.
