You can always have AA AK KK JJ so in poker you are good or your skill are valuated when you play the small hands like monster that separate the average player from advanced or pro players. You must bluff in some situations to win the hand and stay in tour with good stack of chips, as blinds are getting bigger and bigger. Depends in what type of tour you are bluffing and how much. In slow deep stack tournaments you should using bluff in quite small situations, in normal or fast tour. you need to be more aggressive in order to maintain your stack. First you must be part of the table, if you are in constant fold then even the double blind raise, will turn the alarm at others players because of your very tight play. When you are more included in hands its very difficult for opponents to mark you as a calling station or you are having luck and getting solid starting hands often. I don't recommend to be so much included in the games but I don't want also to be distanced quite much, because you cant wait to have only good cards to play, its impossible its poker! So after you decide what kind of player you are, then you need that to transfer to other players. Its very important from which position you are doing the business, big b,small, or other, begin with bluff pre-flop so players will be informed that you "have" smt, then continue with maybe check-raise or all in after turn, but be careful every time, watch how much time will be needed on that player to bet or check, usually fast check mean nothing or monster on flop, also if you bet and you are raised very fast often that mean strong hands. But knowing this "facts" you can use them in your benefit. It's called reverse psychology, ex: When you want kid to do something, just tell him not to do and from knowing their level of intolerance they will just do the opposite. This is example of reverse psychology, does not mean that every time will be effective. So bluff comes with the years of playing and more played hands. Very important information is how much is starting capital. If players lose 2/5/10 dollars for someone that does not mean much, but for others it is. So if the starting capital invested is key. If you are on the edge for winning 1500$ and you invested 10, sure you don't want to lose with bluff at this time and having argue with yourself why you do that. Knowing when and what that will bring to you is a key, that's how bluff should be sometime small sometime big and winning with bluff is more satisfying then winning with poker A's, but the question is: Does he will fold ?
