Using PokerTracker to track your opponents play
You’ll often see players described as things like 27/18/2, well what does this mean? The first number is VPIP, the second is PFR and the third is AF.
Voluntarily Put $ In Pot % (VPIP) – this shows how loose a player is preflop, it is the best tool for estimating a player’s hand range. You want your opponent’s VPIP to be as large as possible at low stakes, the more hands they play the worse they usually are. You need at least about 50 hands to be confident assigning ranges based on this stat.
<15% is very tight. They are only playing super premiums from early position and only slightly loosen up in late position.
15% - 22% is tight. They will usually be a bit looser from early position then the <15% players, make notes on whether they play PPs from early position or not and whether they raise or limp. They tend to have a much wider range in late position.
22% - 30% is semi loose. They’ll usually open all PPs and strong non pair hands, like suited broadways and strong aces, from early position. They will have a wide range from late position.
30% - 40% is loose. These players are usually playing too many hands in all positions.
40% - 60% is very loose. They’re playing all sorts of trash from all positions, these are the type of players you would like to have at your table.
>60% is free money.
Preflop Raise % (PFR) – is the percentage of hands your opponent is raising preflop. It must always be less or equal their VPIP and should be analyzed in context with their VPIP. A 60/18 is not that aggressive, while a 20/18 is an extremely aggressive player. Again you need at least 50 hands to have confidence in this stat.
If their PFR is very small (<5%) then you don’t need to worry about getting raised off marginal hands. If they do raise you can fold nearly all speculative hands unless you have the implied odds to call and stack them with PP type hands.
If their PFR is <1/2 their VPIP, then this player is fairly passive preflop and limping over half the hands they play.
If PFR is between 50% - 75% of VPIP then they’re raising more than limping but they’re not super aggressive.
Any player with a ratio >75% is raising the majority of their hands and are aggressive preflop.
Aggression Factor (AF) – is an indicator of postflop aggression. It is calculated as (raise% + bet%)/(call%) postflop. It’s the ratio of times a player is aggressive vs. times they’re passive. You need at least 100 – 200 hands to be confident with this stat but more hands for tighter players.
It’s important to look at this in the context of VPIP and other stats to work out what it means. One of the limitations of AF is that it doesn’t include fold% so two players with the same AF could have vastly different ranges for raising.
A weaktight nit with a VPIP of 12% is going to make much stronger hands on average and fold his marginal hands more often then a maniac with a VPIP of 65% who bets and raises with random hands.
The weaktight nit will have a high AF because he often folds unless he has the nuts so a raise from him will often mean a strong hand. The maniac on the other hand might have the same AF but since he’s playing more hands preflop and folding fewer hands postflop his range for raising will be far larger.
It’s important to be able to tell what type of player you’re up against. Take note of the type of hands they show down, the maniac will lose a lot of hands at showdown while the nit will go to showdown infrequently and often with monsters. Using AF with WtSD, W$SD and W$WSF (explained soon) will give you a better idea what type of player you’re up against. Looking at how they react to cbets can also be a useful indicator.
Some rough guidelines:
<1.5 is passive, these players are calling a lot and betting/raising very little, a raise from these players usually means a strong hand. You can value bet lighter against these opponents because they tend to call with wide ranges.
1.5 – 2.5 is about average. These players aren’t overly aggressive postflop but it’s important to look at it in the context of their VPIP and other stats.
2.5 – 3.5 is aggressive. Be prepared to assign a wider range to bets and raises.
>3.5 is very aggressive. These players prefer to bet or raise rather then call and may do so lightly. Against these players it may be profitable to induce bluffs. As mentioned, in some cases a high AF can be an indication of a high fold%, so don’t just assume they’re raising you light.
