NLHE Foundations Course #04: Pre-Flop Ranges (Part 1)

When you're looking at how much you think they're raising with, you need to realize that they are not raising with the same hands from all positions (which is part of the point of this exercise). This means you can't put them on a "raising range" based on how often they raise pre-flop. The stealing range estimate is a little different because it's talking about open raises from specific positions.

fair enough. so for the numbers that i was using as a "raising range" - this should be used as basically the widest they go? like assume its their button range and then shorten it by position?

Okay let me break this down for you real quick in a way that will hopefully make sense.

Your attempt to steal stat (ATS) is the percentage of the time a player will open raise from the cutoff, button and small blind combined.

Your pre-flop raise stat (PFR) is the percentage of the time a player will raise when given the opportunity to pre-flop regardless of position, previous action, etc. This includes open-raising, raising after limpers, 3-betting, 4-betting, 5-betting, etc.

What you'll normally see is a player who has an ATS that's a bit higher than their PFR. For example, in a six-max game you might see a player who has a VPIP of 22, a PFR of 18 and an ATS of 35. The reason for this is that they are raising before the flop more often when there are fewer players left in the hand.
