I hope this message finds you well. I hereby inform you that it is of utmost importance that you study and classify your opponents to improve your decisions in a more forceful manner.
I agree. This is especially true if you play with the same players often. An example that fits well in this situation is our CardsChat
freerolls. From the very beginning of my participation in the community, I played in our wonderful freerolls, and I quickly realised that notes about the players - members of our community can be very useful. And I started to meticulously make these notes on every player every day, if possible. And these notes often helped me make good and correct decisions.
However, I have to say that after the next software update, all my notes disappeared and it really upset me. But a week or two later, I just realised that I didn't need my notes anymore, I just knew them by heart and could easily classify every player in our daily freerolls, of course, except for the new players who joined the community recently.
