PFR% -- hand ranges and reraising standards against them

[maurile]

When somebody raises, I always look at his pre-flop raise percentage using Pokertracker (with Gametime+) to help decide how to respond.

To do this, it helps to associate a particular player's PFR% with the particular range of hands he'll raise with.

For example, if somebody has a PFR% of 0.45%, he's presumably raising only with AA and nothing else. (1/221 = 0.45%). In that case, it'd be correct to fold KK to his raise. So what range of hands is someone raising with if his PFR% is 4%? Or 6%? Or 12%? And what minimum hand must I have to reraise against each of those ranges of hands?

I'll try to answer that here. I've started with AA and added the next most likely raising hands to create the following ranges (each of which is associated with the percentage of all possible hands it makes up). Then I used PokerStove to find the minimum holdings that are favorites over those ranges of hands. Life is more complicated than any chart can ever capture, but as a rough first approximation, it's generally correct to reraise as a favorite and to fold otherwise. (There are times to correctly cold-call, especially after other cold-callers, but I'm ignoring that here.)
