the morons that inhabit micro stakes never fold top pair, i have seen quite a few even calling a bet on the flop with ace rag in their hand and no pair
let me tell you what happened to me yesterday
me and a guy who was a sort of "maniac" went into a flop, i had AKo out of position
i don't make a pair on the flop and check, he raises, i know he's bluffing, i re raise, he calls
the turn is a blank, i still think he has nothing (my thinking is he called because he is simply an idiot), so i bet again 1/2 of the pot thinking i'd win but to my surprise he calls
the river is another blank, i'm thinking i was wrong and he has some random pair and will call a pot sized bet anyway so i give up and check, waiting for the raise so i can fold
now comes the funny part: he checks behind and shows AKo and we split the pot, both with ace high and king kicker
