Luv your sig line. I need 4 cards to get any 2 of mine to work.
I'm sure there's a ton of advice out there, but nothing short of playing good hands
when you have them, and play them hard. I play fairly tight as well, but poker IS gambling
and there is risk unless you know on the river you have the absolute nutz.
The shorter your stack gets, the harder it is to play out a good hand. Collecting chips early is critical to surviving blinds and being card dead for a while. Pick your hands, bets and position to your best advantage and bet. Being tight is OK, but you have to make big moves when you have good hands. It's hard to give exact advice since you don't say if you're talking SnG's or high entrant freerolls
Loosen up a little when you have good hands near mid-tourn. If you bust out, it's getting all your money in with the best hand. If you get beat, at least it's not hours later sitting on the bubble blinding out.
GL and May the Felt be with You.
