Hero?
TAG, not enough hands to give stats, but lets just say 20/18. He does however have about 55% flop c-bet. So it's possible he is checking back here pockets.
Do have notes that he's suspicious in terms of thinking people are floating him on dry boards as he has a range for x/r a blank turn as PFR and folding to a turn 3B. We don't have any history.
Standard line? Should I lead turn? x/c ? x/r ?
If my image is really spewy then is this is a good spot for me to x/r and pot river?
Pretend I don't have a Q here, what is the chance he checks back Qx (e.g. some random Q7s or QJo open), QQ, 77 vs an unknown?
