re: Poker & Small pocket pairs in 45 person sit and go tournaments
It really is table dependent. I'd like to give a cut & dried answer ie. > Fold <66 in EP in early levels, raise with 77+ (but this isn't realisitc... although it might be a bit of a guideline..but again 'it depends').
If you're playing in a $1 -45, I'm assuming that in early levels most EP raises get 3 or 4 callers anyways, & if you actually just 'limp/call' (they likely won't raise enough over limpers anyways) it probably won't be so bad... they're also less likely to put you on a range for when you do actually hit a set.
In a higher buyin, usually 'tighter & more aggress.' table, I'm more likely to just raise or fold sm pp's (usually raising).
So to answer the orig. question (relating to a $1 buyin 45plyr sng).. 'it depends', lol. limp/call, raise, fold.. probably all are okay.
