Quite easily, just stand around and wait for good hands at the start. All-in with QQ+ (or even JJ) or AK and you double up. If you are on a passive table where people don't madly go all-in, you can call with suited connectors or pocket pairs. Call me newbie for this but on IMO position doesn't matter very much here. If you hit the flop you keep playing otherwise you are out of the hand; position doesn't have a big role in such simple decisions.
Usually 60% of the players will just go all-in on those early stages and soon enough you will be in the money and people will stop going all-in and play tighter (usually takes around 1-2 hours on most freerolls for this). On these stages you have two options:
Either you continue waiting for big hands only and wasting time so you end up in the money, or (more recommended) you go back to the normal MTT strategy and start taking risks in order to get to the final table. Here is when you start to actually focusing in the game, trying to get reads, etc.
Now, there a lot of variables at play tho. For example, I'm used to go all-in with the QQ+, AK range and usually get 1 or 2 calls that allow me double up and survive. But it may happen that I'm on a tight-passive table and people simply fold, and I need to adjust my strategy to this.
Then it depends on the prizes too. If the prizes are money and the higher you go the higher you get paid, then by all means taking risks and being aggressive with AQ, AJ, KQ, and hands of the like is good play for me. But if the prizes are simply tickets, then I'll most likely fold those hands pre-flop in an aggressive table, because all I want is a ticket and my rank doesn't matter at all.
Oh and 1 more thing: if your stack is small, then disregard the "wait for good hands thing". You'll just waste time and chances until the blinds go up and you are eaten. Compare your stack to the blinds and go all-in with Ax and hope to get called by KJ or something. If you stack is that low, Kx or QT+ should be in your all-in range too. If you can't survive another BB, go all-in with any suited connectors too. Most likely you will lose but at this point you can't count on winning anyways.
There's also the chance that you won't get lucky and you are doomed. Sometimes I don't get anything at all and end up having to go all-in with almost nothing. Other times, like yesterday, I get stuff like AA, AK, AQ happening almost constantly. I even got an AA vs KK and poker with 99 that granted me some money. Luck has a weight on this too. Most times tho you will be in the middle ground and getting fair-to-good hands 20% of the time, which is what you want.
Freerolls are easy and I feel comfortable playing them while watching TV, at least for the 1st one hour. I always get a ticket on the Hubble freerolls at PokerStars, although I never seem to get more than $.5 on the 100K ones
