I can't call it preparation, but before I start (and, of course, while playing) I ask the poker gods to remember me and help me make the right choice: reset, call or raise. If it works, I raise my hands up and send streams of gratitude, and if not, I tell myself, oh my God, what a fool you are, you had the opportunity and signs to make a decision. I'm preparing a few sandwiches and a bottle (2) of beer and some potato chips in case the game lasts a long time.
but that was a long time ago, now it's time to resume it🙂 👍
