question that gives hand away:
do microstakes players ever fold a pair of aces?

i got a bit cautious after the flop min raise because last time (similar flop against different opponent) i shoved over and the guy showed aces up to my AK. when he checks turn i figure i'm good but i don't wanna get raised again. am i usually beat when he fires river?
