I'm betting for value/protection here esp IP. It's going to be hard to bluff-catch rivers or call rivers and we have the best hand here OTT so often we only really lose to a 9x type hand.
If we check we are just done with the hand pretty much, like we aren't bluff-catching any/most rivers anyway...

9 shouldn't hit V2, and V1 shouldn't be calling flop with any 9x in his range besides 9
combos for FD.
I think if we do bet for value of course/protection we will get called by worse a lot being a 6x type hand so i think betting is perfectly fine and +EV. Also we get villain's to fold hands with decent PE vs. our hand like 1 over + FD which is good i'm just going to make it 30 here.
