It is important to keep notes of the players.
Good afternoon everyone, I do take notes, I think it's fun, the notes I get from players are much more important in cash games than in Mtts, I like to play both styles, 55% cash and 45% Mtts.
When I started to play and watched videos of players talking about the impotence of taking notes from players and today I know that it is very important, when I mark a regular player, my top country doesn't have much lavor and when I mark the recreational player my top country has much value.
