Id been thinking about this a lot recently:

You have KK in late position or blinds and EP raises. You reraise 3 times his raise and he reraises to 3 times your bet. Do you shove or call? and how do you play the flop? Or do you lay it down?

Having got burned shoving a couple of times I decided to call and that just left me facing the obvious flop shove with a missed K. So I was unsure what to do.

Then, for some reason, while 4 tabling last night, the situation kept happening with other people at my tables and QQvsJJ, QQvsAK, QQvsKK and similar all being shown convinced me that at my buyin level, folding it cannot be correct. (Not unless I guess you have like 10k+ hands with a guy and have seen him flat call repops with JJ-KK and only ever rereraise with AA)
