Most poker sites allow you to take
notes and colour-code players. On
PS there are 8 colours, so I think my ranking system goes something like this.
Red = Deadly reg
Orange = Ordinary reg
Yellow = Meh reg
Dark Blue = Good, not reg
Light Blue = Bad reg
Purple = Spazzy reg
Pink = Spazzy
whale
Green =
Fish
The answer you are looking for is that you can't
tell if players are regulars until you play a couple of sessions. I have a very good visual memory so I can usually identify when I've played players before. Your
HUD will then confirm how many hands you have a particular player. You can make certain assumptions like if you see a player on most days, he's obviously a reg. If you have 500 hands on a player, he's more than likely a reg. Most regs tend to fall into the 10/8 - 15/12
VPIP/PRF during the first two levels. If I see those figures over small sample sizes, I usually make an assumption that they generally know what they are doing and it's ok to assume they are a
regular or are at least semi-competent until you see otherwise.
If I deem a player to be a reg, I usually
tag him orange him. If I think he's very good, he gets the red
tag eventually. If I see him do something dumb, he'll get downgraded to yellow,
light-blue or purple depending on his mistakes and the frequency with which he makes them. Occasionally I'll move players up a bracket as mistakes can be mis-clicks or an infrequent error.
Oh, and you can see the colour-coding in the
PS lobby, which is really handy. I avoid games with more than 1 red, orange or yellow player.
