JJ line check

Am I the only one that thanks Hero played it fine? I would sometimes find a fold on the river, but 5:1 on your call...

I think this is fine too. On the river I think he might show TT/busted diamond draw/air just often enough that I call here. How are his postflop aggression by street stats?

Edit: and thanks for changing your avatar back gimme :D
