I made so categories of how the play taking on perspective my own way. So I note them as agressivier or passivier than me, as so as looser or tighter them me, so I know how to adapt my game playing against them.
Sometimes I take notes, but I believe that I have to take more into account the current table, players tend to play differently depending on the table or even evolve and play better, so I don't always take notes so much into consideration.
mental notes to remember at the table that I find which are the most bluff or those who play only high cards to know when to go against them depending on my hand
Yes of course! I think that take notes about your opponents, can give you information in the next tables and you can play better with this information 🙂
