I'd much rather call this pre-flop, especially vs a min-raise... In fact I think this is a definite call, 3betting makes no sense whatsoever in my opinion. Villain has 75bb, it's not such a short stack, we get ridiculous odds for calling pre, have a hand that has great playability post-flop... we can flop gutshots, flushdraws, TP + overcard, mid-pair good kicker, backdoors + mid pair, TP bad kicker.... anyway, just a bunch of stuff which gives us playability post-flop.
Villain is gonna have a bunch of hands that dominate us, thats for sure, but he'll also have a bunch of hands that we dominate. So, as long as we play a solid post-flop game and don't play for stacks on a K-high board, if we are able to properly acknowledge our hand strength on the different kinds of flop, we have to call pre. By 3betting, we isolate against those K's that dominate us, which will not fold BTW, meaning we don't make better hands fold, which is the purpose of bluffing, right? Making better hands fold...
When you do 3b, you cannot call his 4b. I assume you 3bet as a bluff right? So if he shows aggression, give up your bluff. You can't bluff-call.
When you do call, I'd rather c\c the flop or c\rAI, but probably c\c... I guess it would depend on bet sizes and villain.
