Good morning everyone, poker is a game of information. The more information you have about your opponents, the better your decisions will be. I play at micro stakes, and my notes help me a lot. In my opinion, players from these limits who are from Germany tend to include a higher number of recreational players. I believe this happens because poker is very popular in Europe and Germany is the richest country in Europe, so many players deposit money just to play for fun.
In CardsChat freerolls, my notes almost always help me a lot. Against players marked as strong, a top pair is rarely enough to play big pots (60 blinds or more). For example: open with AKo from UTG with 35bb; the villain, marked as a strong player, calls from the SB with 36bb. Flop: Ac 5d 9s. The hero bets and the villain check-raises. Most likely, the villain has 55, 99, A5s, or A9s — and in most cases, AKo will be behind against this type of player.
On the other hand, against players marked as recreational, AKo on this board tends to be ahead most of the time. These notes help me a lot.
