You have to find the right mix. Basically, you hardly have more than 20 big blinds at the final table. As a rule, you are more likely to have between 10-15 big blinds. That means you will have to play tight. Because you don't want to have to pay a tenth of your stack to see the flop and then fold straight away because you didn't hit anything. That means either raising or folding. In early position I would only raise with JJ +, AK, everything else I would fold. If no one raised in front of you, you can also raise in late position with AT +, 88+, KQ. In addition, I would do resteals. Basically you can apply resteals with 88+, AT +. But pay attention to the position of your opponent. If an opponent raises in early position, you need JJ +, AQ + to justify a resteal. If your opponent is on the button and is the first to raise, you can resteal with AT or 88. Are you in the small blind and no player has entered the pot and your opponent in the BB has fewer chips than you then you can put all in with any two. In this situation you have a high fold equity and can therefore put all in profitably.
