50NL, full ring. I won't post the entire hand bc it does not really matter. Just the information I give is relevant.

UTG min raises to $1, has 30BB's. I am in MP and isolate 3bet to $6 with KK.

Everyone folds to the BB who then pauses for a few seconds then pops out a 4bet to $24, 1/2 of his stack. BB and I cover eachother.

UTG then folds.

The key point is that BB, over 130 hands is 14/12 and has not 3 bet even once yet, much yet sized a 4 bet this large.

What would you do?

I am mainly a 6max player and KK here is snap shove always bc AKo and AKs and QQ are partakers in 4 bet sizing like this. But this guy doesn't join the 6 max tables and only see him on the few full ring at this site.

Please oh full ring gods, would you smite me if I folded KK here next time?

As played I did not fold, even though I realllllly wanted too. Villain of course had AA. I lost my stack.

That's ******edly large 4bet sizing, but I'm still stacking off with KK as i expect to see QQ and AK an unnegligible proportion of the time

Its obviously a fold. He had AA......
