What sucks about flopping the abs nuts is that you cant really profit from this as much as you could with something like hidden trips, eg. 22 in a AJ2 flop. With something like AAK you hope that another player in there has an ace. If not you giving ONE free card cant reallyhurt you, a free card might give somone a flush draw, or someone with JT or QJ could make a straight ( very longshot )
