hand 1 - just call the flop, but you might have to get all in anyway
hand 2 - only do the overbet shove with kings if you've already done it before so it looks like it's your standard 4b size
otherwise it's a cooler
hand 3 - bad beats are bad (this is not a cooler, but a bad beat)
hand 4 - coolers are cool (this IS a cooler)
