i need some help with styles of poker..

when i first learned poker..i was taught what i later learned was short stack strategy..playing very few hands, playing only premium starting hands like AA KK QQ AK, etc. & playing them hard..

now i dont play @ the cash tables much..i play MTT & larger SNG..plus
a boatload of freerolls & k.o. tourneys..

Is there a better style of poker than SS for playing these larger field games?
because i dont play alot of hands i find myself constantly having my blinds stolen & getting blinded out of tournaments because of lack of good starting hands..oh yeah.. & occasionally getting too aggressive with starting hands trying to play SS strategy..
can any1 help a rookie out here/?

thanks in advance.

Playing the short-stack-strategy is completely ok for the earlier stages of any MTT.
In medium and late stages you might want to open your range (just a bit) if in position.
After antes have set in stealing some blinds or even pots will be necessary, too.

There are several really good threads in the strategy section here.
Read them and if you’re finished - reread them again
