I'm betting rather big on this turn to set up for a river shove on any non-9,K,A,diamond.
If someone raises the turn I'm probably GII. They could definitely have some 2pairs or sets that they want to protect.

I dont get why you are so concerned about getting called in this wet flop. There are like infinite combos that the players might have called you OTF and you are only losing to AK (but nobody has it since its an obvious 3b pre with all that people involved in the pot) and K9, and you block some combos of that. You should bet turn big and shove river on most cards, as knoxox said. Big hands don't come very often, so make sure you get the max out of them

Ok, so because the flop is so wet it always is 3xbet, unless the flush completes on the river?
I ended up betting turn, and they folded... but was just wondering what to do on river vs call...
Thanks for the insights!

It's a classic example of 'I have da nutz, the board is super wet - let's go for max value/protection and bomb most runouts' - I would just pot each street and happily GII vs a raise.
