If the blinds are too high in ratio to your stack you may be in a push/fold situation. Personally if I have 15 or less bigs I’m shoving preflop when blinds are high. If blinds are creeping up on you often you may want to open up a little bit in position, and card selection needs to be less picky. You don’t want to just blind off your stack. Sometimes we have to have take a risk and hopefully reap the rewards. In position aggressive play is highly successful, and/ or shove against a player that’s been stealing a lot , you can resteal some pots. Collecting the Blinds and antes add up deep.
