Changing play style

At what point in any type of tourney does one change thier playing style?
At the beginning of a tourney I'm tight/aggressive.

You will need to change your playing style many times within a tournament. And it is not a constantly increasing spiral of aggression.

I dont think you can narrow it down a great deal (in terms of when exactly to change, and what to), apart from the fact that aggression levels should generally increase in the lead up to the money, and as tables become shorthanded (eg final table).

Each tournament is different. And adaptability is important.

At the beginning you should obviously consider blind speeds, starting chips and payment structure. Is TAG really what you want for this particular tourney?, and if so what form of TAG?

As the play evolves your strategy can and should change alot according to how your stack develops or dimishes, relative stack size, blind level, how your table image is currently at the table, how the others at your table are playing, and how specifically a player you are up against is playing. If a player cant evolve their play continuosly in order to take into account all these factors, then they are doomed in the longterm.

Good Luck

I would recommend you read about Dan Harrington's "Zone System". He covers it in 'Harrington on Hold'em: Vol. II', but there is plenty of information on the subject online.

It is basically an outline of how to play depending on your stack size relative to the blinds. It's helped me a lot and my results have been much better since I read it.

Thanks for the input guys and I'm sure to look up your advice Sponge(bob...lol)toe.

Basically, your playing style should be the opposite of what the majority of the players at your table are playing. If most of the players are playing tight, you play loose and vice versa. Your playing style will change many times while playing in a tournament.
