Don’t be afraid to bully with the big stack
If you are the chip leader at the table you need to use it to your advantage. People are going to be afraid to get involved in a hand with you unless they have some good cards so if you sense weakness be aggressive and bet big to scare people off a hand. We see a lot of the time the person with the big stack plays too conservatively and dwindles away their chips never really taking advantage of the power of the big stack.
