the reason for an allin is to put the tough decision on the other player. I would much rather have no decision (an allin) than a tough decision, we can only make each decision given the information at hand and every bit of poker is about presenting misleading information or misrepresenting your holdings, put the tough decision on your opponent and realize you are ahead more times than not. You are more likely to get him off of his hand if he has middle pair, Ax or even a stone cold bluff. I agree that only premium hands call you such as AA,KK,AK,QQ,JJ and maybe if your lucky worse hands than that. We want AK to call. JJ, of course. Only hands we are WB is AA, KK. Any flop is threatening (8d,7d,4h) when your opponent then pushes allin after the flop. What are you going to do then. Did he hit a set, a straight, is he on a flush draw? More times than not we are ahead with this hand. Push and take whats in the pot now. When he folds, you now have sent a message to the rest of the table. Don't mess with me fellas. When he calls and you whoop his butt, your sending another message that your not scared to gamble it up with significant holdings. when he calls and you get your butt whipped (again fewer times than you think), then you get to go home and watch Letterman and don't really care what they think your table image is, because your home.
