Very important to tag the villains.
Good morning everyone, I think it's very important to mark the villains, I play a lot of cash games and players that I have notes from recreational players I usually play big pots with medium hands, eg AKo on the TA 5 flop, vs recreational players mostly I'm winning this hand, but vs regular players I try to control the pot size almost whenever you are going to play this hand against good players making big pots many times these players will have trips or 2 pair after the river.
The notes in play helps a lot in decision making.
