I've been busy with work and unable to put much time into the Poker lately, but found some time to do some work this morning.
In order to get some feedback on my VPIP analysis, I posted on the 2+2 forums here: http://forumserver.twoplustwo.com/39/small-stakes-pl-nl/does-vpip-really...
It will be interesting to see what sort of response I get. Most players have been led to believe that tight play is better. However, the data from the PokerFtp database suggest that the belief is inaccurate, and that loose play can be as effective as tight player.
