Poker position
Poker is a game of information, where many players meet, and the one who gathers the most information, processes it best, and makes the best decisions wins.
Poker position frees our hands at the poker table because we get a lot of information about what our opponents intend to do, the strength of their hands, and so on.
Poker positions: early position (EP, EP+1, EP+2), middle position (MP-1, MP-2, MP-3), late position (CO, BU), blinds (SB, BB).
