The way you choose starting hands in the three phases of a tournament are all completely different. The three phases are beginning, middle and end game.
In the beginning, you want to either play very tight and let the beginners knock themselves out, or you can try and get a fast double up before the blinds get too high. Mid game is generally when you’re playing position and decent hands. Bubble game is when pkv game you should get aggressive. “In the money” game is very dependent on the feel of the table.
In The Beginning
You can choose either to play extremely tight or extremely loose. Note that even if you choose to play loose pre-flop, you should still play tight after the flop no matter what. Don’t go chasing overcards just because the blinds are low.
The idea is that if the blinds are low enough, you can call sub-par hands pre-flop and hope to hit a jackpot flop. This strategy can work great, but it can also eat away at your chipstack. Beginners may often be tempted to chase at this point, which is generally not a good idea.
A more consistent strategy is to just play tight and let the beginners knock themselves out. In any given tournament, there are usually beginners who’ll go all quickly and get knocked out fast. During this phase, just play tight. Play only AA, KK, QQ, AK and AQ, plus JJ in position.
