The best advice I would give you is get to know your opponents and pick the right spot to make moves.
Playing tight is always a good thing if you start, but observing along the way is crucial.
example: that guy always raises me when I'm Big Blind as I'm really tight so I will defend with lower cards that I'm used to.
There's no shortcut to build a bankroll. Practice, read, practice, study, practice. You'll made it with hard work. Nothing else.
That is absolutely brilliant advice, spot-on!
Your strategy so far sounds pretty good to me but I believe you should go into every tournament prepared to change your strategy and adjust your style throughout. React to your table, use position, stack sizes, blind sizes, etc and reads like the example above to your advantage.
Playing tight in the early stages is almost always correct, the blinds are small so less worth stealing and there are a lot of loose players around (in the
freerolls at least) who can luck out and hurt you . However, studying post-flop strategy will help you win bigger pots and lose smaller pots when you do have cards worth playing. Theories like the squeeze play, the semi-
bluff and the check-raise are a few examples of useful tools.
Learning how to play and react to others when on the bubble is important. Also, an understanding of
pot odds, $
equity/chip equity and ICM as well as calculating outs and draw odds are essential for long term success in tournament poker.
