I think in my shoes, I will be checking my JJ combos and going for a check raise, so my checking range is somewhat protected. I honestly think I may be folding 99 preflop to the large 3b and being OOP. It seems like to make him indifferent we outta call some QQ here, but I think the B/C/B line is very possibly underbluffed.

How do we decide here?
