Interpreting HUD Stats 101: PFR
I use this list to turn percentages into ranges. PFR is useful to most players in two ways. Obviously this is not a good spot to get bet crazy. That could be a good thing if you know you have the best hand. With AF, as opposed to just RAISING, we can now more accurately define a players overall aggression and use that on the Schoonmaker grid to create identifiable profile icons of our opponents.
So you are comparing the amount of times he bets and raises aggression to the amount of times he calls passiveness. This includes all kinds of post flop bets like c-betting or reraising, but there is only one type of call. So for example an AF of 1. Lets say over the course of a few rounds at the table your opponent has bet out 8 times, re-raised 4 times and called only twice after the flop. Well that is rather aggressive play but is it the entire story? What does the AF really mean?
Well most good players know when to be aggressive and will be playing with the common TAG strategy of always betting your good hands. So a high AF factor is not necessarily a bad thing. In fact you may be playing against someone who seems to be a nice mild mannered dude who just avoids confrontations for whatever reason. So if he checks and folds a lot as opposed to calling , his AF is naturally going to be higher as a result - because remember you are measuring actions against one another.
A high AF is actually almost always better than having too low of an AF. That's because calling in poker is weak and has no long term value. But think of AF this way, the higher that number is, the more likely your opponent is going to come out firing bets after the flop.
That could be a good thing if you know you have the best hand. Whether it is a minimum raise or an all-in push, the PFR stat will be incremented. PFR is useful to most players in two ways. Estimating Your Opponent's Range If you know how often a player raises pre-flop, by subtraction you will know how often they limp.
If we take an example player with a VP: In late-middle position, this player's stats will probably be indicative of his real ranges, so we'll assume that he is in the hijack seat. This means that when he limps into the pot or calls a raise, he will have a range that is approximately from the 26th to the 12th percentile. I use this list to turn percentages into ranges.
PokerStove is a good way to find ranges and a number of poker calculators have range finders built in. When this player limps along behind other limpers, you can assume that he usually will have a hand in the range between the two. Hands like lower Broadway cards, smaller suited aces, and in some cases suited connectors instead of weaker aces will be his primary limping range. Aggression Indication The way your opponent plays pre-flop can help you get a feel for their whole approach to the game.
He probably calls a few too many raises when the situation isn't as good as he thinks it is and he may limp along too often as well. Knowing that he is passive pre-flop, we can guess that he likes to see flops and may be hoping to hit a monster. Making a standard bet on the flop should chase him out of most pots and since he is a passive player, you will not have a lot of trouble playing against him.
