20 times the big blind or less, you fold or shove, you dont raise min, you dont raise 4 times the big blind(happy eejit?) lol, and seeing as im def not folding KK, im def shoving with 15 times the BB, ESPCIALLY if there's antes to go with it...you'll gain 3-4 extra big blinds...MORE FIREPOWER...
also, ffcowboy, he didn't do anything wrong in the hand, he got called by a player with a bad read and that player got lucky, it's poker....
