I used to 3-bet this kind of stuff but this hand is never in my 3-bet range here, just because it doesn't deserve to be given I'm not 3-betting this spot absurdly wide as a bluff. It's obv +EV, it's just the whole long term play vs short term play thing, what's the optimal 3-bet bluff range. There are a large enough % of hands that play better as a 3-bet bluff than this, but are too weak to flat, that we don't want to 3-bet this IMO.

I like betting flop as i like the prospect of being able to use my mega equity to get him off some better pairs by the river and of course we're doing awesome vs any range to get it in on the flop so if he raises that's all good.
