How is he to know when he has big slick, AA , KK, QQ if it is played the same way every time? If big slick is up against QQ, it is a coin flip at worst. big slick is going to run into trouble now and then and hence the reason I do not like to go all in pre flop for the most part.
Playing live like I do, I am also looking at any clues my opponent is giving me. I desperately try to play with people with less skill than myself. I am a hunter looking for prey not a gambler.
