You need to tighten up pre-flop, but come out firing when you are delivered the goods.
ESPECIALLY in a tournament.Cash game you can reload until the cows come home.But in a tourney you have to watch your position and the levels.DEF raise the premium hand AA,KK,QQ,AKs,AK,AQs,AQ,AJs.Limp with JJ,TT,A10s,AJ,KQs,QJs,J10s,KJs,and Q10s when you can.Otherwise fold fold fold.Unless you're short stacked;then you're playing all in or fold poker.
