Flop seems relatively standard to me, but comments are welcome.

We have 80% pot left in stacks. Perhaps this is more simple than I'm thinking, but decisions in pots this huge are a very large contributor to your EV.  It's important to get them right.

Ben will be defending against my flop cbet reasonably wide, given that he has 7:1.  He's not going to go crazy because obviously this board is great for my range, but he will still have some weak hands. This means that along with legitimate hands, I think his range will consist of 6xxx, 75xx, QQxx, or even J987 with double backdoors, given the price he's being laid on the flop.

I believe that all options are viable: bet tiny, bet small/medium, jam, or check.

I wrote out my reasoning and then deleted/saved it because I'd like to see what people think without influencing them too much.
