Some other statistics that you should include in your HUD are WTSD and W$SD.
WTSD(Went to Showdown)-this will tell you if your opponent is a call station who will take Ace high or bottom pair to showdown. If your opponent has a low WTSD% your more likely to get away with a bluff as they are likely to be only taking strong hands to showdown, on the other hand, if their WTSD% is high your better off not to bluff as they are likely to call you.
W%SD (Won money at showdown) works hand in hand with WTSD%. If a players WTSD is low but their W$SD% is high, this tells me that they do not go to showdown often but when they do they have the goods.
As you get use to using a HUD, you will want to add more statistics. Most programs with a HUD allow you to create custom 'profiles' (different sets of stats/ layouts etc for different situations) for example, if you are multi-tabling space may be an issue- you may need to just have the basics displayed. Also, you may want different statistics displayed for tournaments or heads-up situations (we are currently working on an article with this info).
Some other stats I personally like to use include-
3Bet pre-flop- This is the percentage of times the player made a 3Bet (re-raised a raiser) pre-flop also Fold to 3Bet PF- this tells me the percentage of times a player folded when facing a three bet pre-flop.
I also find it useful to know if a player plays position, here you can use a steal success statistic which will tell you the percentage of times the player won the pot immediately when making a steal raise (a steal raise is an open raise by the cutoff, button or small blind). You may also find it useful to display a fold steal to re-raise statistic which tells us the percentage of times the player folded after making a steal raise when one of the blinds re-raised.
You will also be surprised to find if you use statistics such as bet flop/turn/river how often you will know what a player is about to do (bet or check) and how predictable some players are (always betting the flop and turn then checking the river) and how easy it is for you to call their flop and turn bets with the plan to bet at them on the river, you can even have a call river bet statistic so you know the likelihood of them calling you.
There is a wide array of statistics you can use in your poker tracking software that will give you an advantage over your opponents.
I suggest you start with the basics (hands, VPIP, PFR, AF) and then work from there what statistics you find useful to make decisions in game.
The most powerful HUD on the market today is by far PokerTracker- read our review HERE.
