Thanks. That is easy to understand, but I would not got to this for myself!This is the explanation.
Imagine you're playing a 6-max hyper, and as luck would have it you start in late position. For the first 3 hands, someone shoves before it's your turn, and you have trash so fold. Soon enough you are in early position, and get dealt a hand you can shove - and since no-one has acted before you, you can and do shove.
You've now had four opportunities to VPIP, of which you took one:
VPIP = 25% (1/4)
But only one opportunity to PFR, since prior hands had already been shoved and you could only call. You did shove at this single opportunity:
PFR = 100% (1/1)
This explanation was borrowed from another forum- thanks to dave pooh bah for their insights
Thank you for the complement!Eetenor gave the explanation already. Just want to add, that if someone have shoved, but you cover, you can still raise, and this will count towards your PFR. So if for example UTG had moved all-in for 8BB, and it folds around to you on BTN with 9BB, and you decide to fold, this will lower your PFR. Whereas if you overshove for your 9BB, this will increase your PFR, even though you are essentially just calling the shove. But basically a PFR higher than the VPIP is something, which can happen, if people are short stacked in a tournament, so that when its their turn to act, they can either call or fold but not raise.
