Flop seems like a clear check as I have the deck crushed and they'll bet wider than they'll call a bet.  I can get 2 solid streets on tu+riv as well as rep more bluffs on say the 6h, as well as let my opponents catch up a bit.  Also protect my QQ-99

Turn I think I should be leading since it's a better card for my range than villain's and when I check he'll likely give up w/ his bluffs and check back most 5x so betting gains from 5x.  The downside is that I just don't have many(any?) bluffs unless I start turning stuff like 99-TT into a bluff.

On river, it's a spot where I'll have some QQ-99's, but a large chunk of my range is Kx.  I also have no air at all, so I'm thinking sizing like 12 w/ range is best.  I can probably get away with turning some of the worst bluff catchers I called flop with into a bluff now even with that sizing b/c I've just got sooo much Kx.

I'm not a huge fan of a river x/r with this combo since villain isn't likely to bluff, nor will he value bet non FH 5xxx.  I make more by betting smallish.

Thoughts?
