stealing blinds, bluffing
, semi bluffs, chasing draws, position raises and changing gears will win you tournaments.
but that is when you're in the money
to get TO the money you only need to get involved in a few hands.
play TAG and take down huge pots 3 or 4 times and toss rags and you should make it to the money
once you're there you going to need to change gears and start playing a wider variety of hands.
then when you make final 3 or 4, don't be scared to go all in with rags when you're on the button, just remember that your opponents also want to finish higher in the money and will often fold hands like A9, A10, 88 etc when being pressured by an all in bet. Don't do it too often though but outrageous bluffs are sometimes needed.
you need to adopt this if you're short stacked or big stacked.
One tournament I remember clearly there were 3 of us left , I was the middle stack and I pulled 2 massive bluffs in succession with rags and both times I showed my bluff, the very next hand I got KK and went all in again, and both guys called. I knocked one out and crippled the larger stack. very next hand again I got JJ and did the same thing, he called with A rag.
sometimes its good to show your bluffs
