my thinking was this...
had it been an all-in without the previous raise, it is defintely an instacall...that reeks over an overbet, obviously, and probably a middle pair...i'll call that instantly...but the all-in that was re-raising an EP raiser...that to me, just smelled too much like AA or KK...AK if i was lucky...decided I would wait and try and find a better time to get my money in...
