Running high pfr makes sense against passive pre flop and weak tight post flop players..like demiparidigm wrote these are the most profitable players - http://www.flopturnriver.com/phpBB2/...ic.php?t=20631 But then it needs to be toned down against call stations/maniacs both pre and post flop. Then it's necessary to not get into dumb plays post flop. Basically, from what I read here and tried out lately on hollywood 50nl shorthand, your avg pf stats don't matter as much as how you adjust to the players/table and play post flop. Kinda general, but I'm basically saying it prob doesn't matter much, as long as you win over a long run.
