I agree with you, managing our emotions is one of the basic skills a good poker player should have. Such characteristics as patience, concentration, perseverance, I would also add here. A good poker player must be a universal person, he must be able to adapt to any table and to any opponents, he must have a good feel for the game and understand what is happening at the poker table. Also, this person must understand in which situations it is necessary to call other people's raises, and in which it is unnecessary, and for this he needs to know theoretical knowledge about poker. Poker is a science in which there are many different subtleties and nuances.
