Yeah, I definitely remember some players. There are a few I just can't forget, especially if I lose a big pot to them. I even check the tournament members list sometimes to see if they are playing again. If I notice the same player at my table, I usually pay more attention to their actions and try to remember how they played against me before. It doesn't mean I automatically change my strategy or try to get revenge, but I definitely keep an eye on them. I guess I can be a little bit vengeful sometimes, But at the same time, remembering these players can be useful if I focus on their playing patterns instead of just the fact that they beat me.
I play too many tournaments across too many platforms to remember individual players—though, come to think of it, I do recognize a few screen names, even if I don't have specific notes on them. As for closed tournaments. Playing a specific strategy against a particular opponent is really more of a cash game thing.
In online poker, special programs known as HUDs are used for this purpose; they display statistics for each opponent.I remember it anyway, without notes.
