Dear Friends,

What is better when you CO and have 15bb with KJs to push or 2x raise fold. I see many times how regular players raise 2x and fold to push having 12 - 18bb. Can somebody explain that ranges need to raise fold, to raise call, push when you have 12-18bb in EP, MP, CO ,BU.
Maybe somebody knows some articles about this question please give me a link.
