1. Is it fine to 3b this hands vs. regs this deep?
2. What if we where 100 BB deep?
3. In what case would you flat it here, if ever?

Not sure I'm 3betting very much at all bb v btn 200 deep.

No wizard on playing these hands 200+BB deep OOP whatsoever. But my preference would be to flat. I'd probably fold this very infrequently, call it mostly, and occasionally 3b it. But I really think we're gonna get ourselves into some icky spots, and especially if you're like me and feel absolutely compelled to barrel certain textures when you have little to no SD value (gonna happen with this hand a lot) it may be best to avoid 3betting it.

I'd size my 3b bigger vs a 3x open here with my entire 3betting range. 12BB's seems about right this deep OOP.

It would depend on the regs fold to 3b, but if, for instance, it was high, or villain 4b's a lot and doesn't flat much, I'd be alright with 3b/f'ing this 100BB deep. Think I'd be less likely to flat it 100BB deep, and my default would get closer to a fold, depending on the villain.

And +1 for Definite Article. My 3b'ing range in general becomes a lot narrower this deep OOP, especially if villain is any good.

1) reg with leaks - cb fold too much, check face up range too much etc.
2) fish
