Interesting spot ...
1) In an ABC world you 3-bet to isolate and hope it's not a set or 78s flip.
2) In my world I normally like to start a side pot in case I'm crushed in the main ... See #1 at 80bb as suggested
3) In some of my world with a Super Nit involved and not knowing what's going on in the SB I might announce a fold (here comes the ripping) and gladly show my 'wtf' fold to the Nit/table if the SB folds quickly as well. I would probably only do this if CO had chips behind ...
I think in this case here I rarely fold as it's just not enough to even consider folding and I can open the side with basically a min-raise and see what happens with SB.
Yes, it's a crazy thought here but this fold 'may' create one or two things on the table. One, it can drive a Nit crazy when you show this kind of fold and two, the table sees it and may play back at you more with weaker holdings. I've had 'the Nit' leave the table when I made a fold like this before and the table was all smiles about it ...
Leak? For sure, fully admit, full disclosure ... but it sure is a fun way to crank up a table. GL
