re: Poker & VP$IP Question...?
For FR I wouldn't classify 12 as very tight, in fact it's probably on the loose end of the TAG players who profit. Basically most TAG players are ~8-14 I'd say, but otherwise I'd agree with the above list. Of course there are the EXTREME nits with VP$IPs below 5, but they are few and far between. I just think 12's a bit too high to be "very tight" and 20's a bit high to call "tight/normal". Anything really above ~15 is getting loose. Just know that VP$IP doesn't really determine winrate since a superior post-flop player may be correct in playing a wide range of hands just to outplay opponents postflop.
