This is incorrect; not paying attention to someone's playing tendencies is clearly a bad thing to do, even if your opponent is very aware that you are paying attention to his playing tendencies; if he understands that iniative does not exist however, it stops being profitable for you to make moves purely based on the idea that it exists (for example, if you told him your exact hand range raising from the button, and told him you were always going to bet if he checked to you, obviously he would ignore iniative and play against your hand range.

But the idea that your hand range is guaranteed to be better because you raised on the last round (you would never call with queens, but you would raise them) has merit; however, does it not also make sense that if the opponent has an accurate interpretation of your hand range, he should make his moves purely based on the merit of your hand range and not on the merit of his 'represented' hand range?

EG: I am not going to start folding ace high on the flop against someone who raises 100% of hands preflop and then always cont bets; this is because he has demonstrated that his hand range is weaker than his betting represents. His 'seizing the iniative', as a ploy, is useless, because as anyone with a clue will realize, his hand range is disconnected to his betting patterns pre and on the flop (hence initiative does not exist).

The converse is also true; If your opponent plays 10% preflop, and only continuation bets when his hand makes top pair or better, his seizing the iniative will be effective, as it is clearly representing a strong hand range (and that is exactly what it is).

Since you are playing against a wide range of hands rather than a single hand in most these situations (pre and post flop, by the turn and river, often you have reads that help you narrow it down to less, perhaps even one, hand), it becomes effective for this tight player to add in more and more hands that are 'protected' by the stronger hand range; for example, if he adds 27s (think, Shania), this hand will become immediately profitable if the opponent fails to adjust, since most players will still always fold anything that doesn't beat top pair and play anything that does; but there is a point where he SHOULD play hands that don't beat top pair (once enough non-top pair hands are added). At this point, if an opponent does not start playing non-top pair hands, he is becoming a victim of iniative;

Is this why changing gears is so powerful heads up? Because you force your opponent to constantly play incorrectly, to become a victim of iniative? Since it will never be feasible to correctly interpret the opponents hand range pre / on the flop unless they are aggressive all the time (read, neverwin heads up on button = 100% raise preflop quite often), is iniative a fundamental advantage since an opponent can NEVER tell how loose or tight you are playing at that exact moment because of variance? (except in extreme cases, as above). I have no idea.
