i use them too. they come in handy for all types of reasons. i didnt use it at first. and im way behind on info that i could have had from other players. but i take advantage of it now
I do not know if it is advisable to take so many notes of players in mtt you can add a few but you will be much deconcentrated notes and all that statistics is much more advisable for cash tables and not for tournaments
Making notes on players is a very useful tool especially on later stages that there are more tough decisions or for use in the future.Personally it helps me a lot to understand their range and generally when to make the right call or fold
I use notes on the players. In the notes I indicate the style of the opponent's game; the opponent's actions after the flop, turn and river; bluffing players; theft of blinds; calling station - the main thing that the notes were simple and understandable. The notes help me when the opponent raises and 3-bet on all the streets, tries to steal the blinds.
Yes, I take notes too and I think that it helps a lot... But you can't believe 100% in that notes, because players change and their games too... But the notes can be a information that can guide you through the game action!
