Hero raises to $??
Hero flats???

I'm probably making it $9.5-$10ish.

I would flat on a rainbow flop probably.

Yep I like clicking it back. He might think he still has some fold equity.

You have the nuts vs. an unknown. Go full aggro.
Raise anywhere from $9 - $13, depending on what bet sizes have been for the last 10 hands (those Villain has seen).

You have the nuts, slow playing is not really an option, since the board is wet enough that you have to donk turn to avoid giving Villain a free draw. GII now while he's still willing to stack off w/ overs and NFD's.

Secure yr self the cooler now before villain can become a hero.

hero does not flat. Hero keeps betting.
