I have seen some stats referred to in many posts, in the form of two numbers -- eg. 17/7

Wondering to what these numbers refer? It seems like it relates to tightness-looseness or aggression...

Thanks in advance!

The first number is VPIP (sometimes written as VP$IP) and it refers to the percentage of pots a player voluntarily puts money in the pot.

The second is PFR which is a player’s preflop raising percentage.

There are numerous dicsussions about these on CardsChat and all over the internet if you do a search.

**Stolen from the net:

VPIP (sometimes written as VP$IP) refers to the percentage of pots a player voluntarily puts money in the pot. If a player’s VPIP is 40%, that means that he puts money in preflop 40% of all hands he’s dealt. VPIP doesn’t tell you whether a player raises or calls (raises and calls are lumped together); VPIP simply tells you how often a player puts money in. A player with a high VPIP is loose, and a player with a low VPIP is tight.

PFR is a player’s preflop raising percentage. A player with a high PFR is more aggressive preflop than a player with a low PFR preflop. The PFR statistic is misused in very similar ways to how the VPIP statistic is misused. First, PFR refers to preflop play only. Players who are aggressive preflop tend to be more aggressive postflop, and players who aren’t aggressive preflop tend not to be aggressive postflop; however, until you have evidence verifying that these trends hold for a specific opponent, using preflop statistics to extrapolate how someone will play postflop is a huge mistake.
