I'd bet large (at least) 3/4 and stack off vs anyone except maybe the 800 stack.

Sort of a range merge spot for me when Hero blocks top set and has non-nut draw. We benefit from playing fast, cleaning up outs and some equity denial, plus with top pair opponents are a lot less likely to bet for us.

Hate the 3x pre. Flop is whatever with this hand imo. I'd bet small.

Why do you hate the raise, and what would you have done preflop?

You are pushing equity, so just pot it. Imo it makes no sense to have multiple sizings pre giving info of your hand.

Why not pot it preflop?

I mean you are OOP and they probably won't fold to pot, so I would pot it pretty much any time I decided to raise.

I wouldn't use OP's sizing either, but anyway it is very unlikely that any of the villains in the hand are capable of figuring out what that info is, and then of actually making good use of it.

The nittier the nits are, the smaller the edge he's pushing will be. Many passive nits in Big O are known to limp-backraise certain classes of hands, which they then play face-up and badly. I don't know if that applies here. If it does, maybe that was the logic behind the small sizing?

Yes. If both are true: they don't understand what 3x looks like and they reveal some hands by limp-reraise then 3x has some point. I would never do it anyway.

I don't think "yeah but they don't understand" is a great way to approach poker in general. You have no idea what they understand and it's pointless to take such risks, because there are simpler and stronger alternatives.
