I fully believe that when playing low stakes that shoveling it all in with AA/KK is always the correct play when you can be reasonably certain that one of the muppets will call.
You are on the button, 4 limpers, a min raise from the cut off, just shovel it in, he will call with KJ 68s 44 AQ or someone in between will. I've played for stacks up to the $200 level and get called by QJs and KQo, which is the suckers AK.
It isn't like it is the most skillful play on your part, but dang it YOU WILL GET CALLED more than scaring them off. If you lose you lose, and there are no more tough choices brought on by your opponents 96o that was played for a 10x blind raise, that same guy is going to call all in.
Just shovle it in and if they fold they fold, if they call they call and you got the best of it. It isn't like these guys are good at making big laydowns or are crafty tricky opponents, their major flaw is calling too much, so shove it in please.
If you doubt, just try pushing all in for a couple of days and tell me how it goes, but I seem to do well with whacking it all in to a bunch of limpers and especially a min-raiser with AA.
