Mistake.
You under-repped your hand in the eyes of the reg.
If fish opens, reg 3bets, you cold 4bet, fish shoves, reg calls the shove, then you have more of a case to fold. But still not folding when theres a fish involved.
theres a lot of fish who will only ever get in AA preflop
"cant fold KK if he is a fish" is quite bad argument, if youre up against AA almost always
but yes, i might have messed up.. i was thinking way more about the reg in pot, than i was about the fish - it is superobvious fat value KK+ only in the regs eyes, but i should just ignore that and hope fish finds something worse
nopp.. they will call KK against a cold 4b, QQ i dont even know, but if i get action against these guys after a 4b, im pretty much ****ed
Ya maybe, but at that point you have more info and can consider folding. If you just flat the 3b a lot wider range will 4b and you don't have any clue where you stand.
