I completely understand that feeling. When you’ve spent years hearing ‘aggression wins,’ it becomes hard to break the habit and add controlled limping into your strategy. But the truth is, limping isn’t weakness by default — it just depends on the situation, stack sizes, and player tendencies.Limping or simply calling before the flop is the psychologically challenging move for me. Literature has emphasized that aggression wins. I have viewed limping as a sign of weakness and avoided it a lot. Currently I'm trying to add limping to their toolbox, but I try it a bit hard not to be aggressive. It is also hard to understand when opponent is actually weak and when it is used as strategy.
