When you have a problem at a certain point in a tournament it usually extends from an earlier point and you are seeing the final result.
The problem isn't the bubble or right after, it is going to be in the middle of the tournament.
You need to start being more aggressive, open your range, and play more pots once the anties start. As there is more and more in the pot you need to take more chances an
build your stack, not float along. You need to be aware of how many blinds you have.
When I have 30 or less blinds I'm looking for hands and to steal blinds. I'm looking to play for stacks.
A general rule of thumb is at 10 BB or less shove because you have fold equity, the problem is many people don't feel any urgency until that point. Usually it's too late and they force the action with poor hands. Start looking to play hands at 20 BB and stay ahead of the blinds.
If you start stealing blinds, taking more chances earlier, you will maintain a larger stack. The bubble will come and go without much of an issue.
You will find that you are going to bust earlier but will go deeper into tournaments which is the ideal result, a minimum cash isn't going to maintain your
bankroll.
