One of the poker strategies is aggression. But only with it you can't always win, remembering that there is a lot of variance in the game. That's why you should be aggressive, especially with your value
hands, but folding is also a tool that, when well applied, takes us out of several situations where we could put our tournament at risk.
On certain flops, checking is the best option and a well applied probe is capable of yielding more than an improper cbet.
Studying the different scenarios and knowing how to play each spot is difficult, but it is the best strategy to use. It takes time and discipline, but it's not impossible.
