running the EV calculation for 55 vs a random doesn't take into account the hands that actually call the all in. vs hands that call the all in, obviously you are losing since all bigger pairs and some overcard hands call. that being said, the other person folds often enough that it is definitely the right move.

i dont like a stop and go against a big stack because he could have any 2 cards. so if the flop comes down 972 and you stop and go, all of a sudden he calls you with 96 and you wish you had just pushed preflop. or you check fold a flop of AK9 when he has like 67s...
