I did that and I have lost the most of the times, more exactly in 80 % of the times, what do you have to say about that ? You will say that I didn't know how to play that hand. I f someone goes all- in pre-flop from early position and you are in the button holding AA what do you do ? And if you call and see that the adversary holds 3 8 of suited what do you think if on the flop comes 5 A 7 ? " I WON !!! " guess again because on the turn comes 6 and the river decides : 4 . Good luck again because this is a hand of many others ...
