a couple of things, a lot of people have sattied into that tourney so the begining stages can be much like your low buyin normal tournie OR they can be nit tight trying to "not screw up". A lot of the players you will also meet are well versed in LAG play, and if your playing scared money they will eat you up so be prepared to re raise or jam, cause that raising fool may have 5 2 off NOT AA. The biggest thing is this, for you, this is a free roll...yes a free roll and that mind set can work to your advantage. I suggest you watch annette 15 blind tourney, to remind yourself that its the moves not your cards. so to recap
1. lots of people will play tight trying to "win" use that.
2. you have allready posted your entry fee (free sorta) so it is "lost" so you might as well go for the win.
3. forget about what you may win in $ terms, just relax and enjoy it, dont be scared money.
4. when close to the bubble, be aggressive as hell, ok you may bubble bust but who cares your free rolling....right, most are tighter than hell and if you can steal 3/4/5 times in a row..do it!
5. some quick rules of thumb, from 2-8% of your stack you can call with almost any two cards (suited cons, small pp, cons, suited gappers" and the other good players are going to as well. This means if your playing a spec hand raise more than that range so they are not calling with "junk". Gus is well known for raising big with junk, now you know why.
If you have or put another person into the position where10-30% pre and 30-50% post flop of their stack is out there, its the same as a allin, use it for pressure and it will be used against you (see raising with ragg's). If you 3 bet with a 3 off, get re raised, you can jam or fold (beter to jam with 2 live than ace ragg imo) using the above formula.
Position, position, remember annettes blind tourney.
not every limp from utg is a monster and even if it is aa that gets snapped off by 2 pair...
You will have to get lucky, but the best luck is getting the other person to fold a better hand, so bluff, trap, and in the end just have fun...dont be scared.
