Crucial stats: VP$IP, PFR, WTSD%, number of hands

From being around the forums I'm sure you have a good idea about these but here are some general guidelines:

- VP$IP<10 = rock, 10<VP$IP<20 = tight, 20<VP$IP<30 = loose, VP$IP>30 = very loose, likely a fish.

- PFR<5 = passive pre-flop, 5<PFR<10 = average, 10<PFR<15 = aggressive, PFR>15 = maniac

- WTSD%<15 = rock, probably can be pushed off hands post-flop, 15<WTSD%<20 = average, 20<WTSD%<25 = slightly loose post-flop, may make marginal calls, WTSD%>25 = calling station

- Number of hands: don't look at anything under 25, and use anything under 50 as a guideline only. Over 50 hands pre-flop stats start to get more reliable, but I still try not to put too much stock in them until I have 100+ hands. Post-flop stats require even more hands (250+?) to become accurate because most players are folding more than 75% of hands so the sample size is much smaller.

Other stats I have on my HUD: attempt to steal %, continuation bet %, fold to continuation bet %, flop/turn/river aggression frequency, fold to fold/turn/river bet %

These are less important and I only pay attention to them when I have at least 100 hands on a player, preferably a lot more. I'd recommend starting with a simple HUD layout, getting used to it and then adding stats as you feel comfortable or think you could get use out of them.

VP$IP = Voluntarily Put $ in the Pot (percentage) - How often you put $ into the pot pre-flop outside of the blinds.

PFR = Pre-Flop Raise (percentage) - How often you raise pre-flop.

WTSD = Went to Show Down (percentage) - How often you go to showdown after seeing a flop.
Use vp$ip to put opponnent on a range of hands. The higher vp$ip is the larger the range is. The more hands you beat in that range, the easier it is for you to continue in the hand.

I also use PFR to see how likely it is for someone to limp a premium hand. If PFR is below 5, watch out.
