When I sit down on a table I look on my Pokertracker database to see what a player my opponents are (fold to a steal, VPIP etc.). However, there are many, many players with less than 100 hands. I think 100 hands is not enough to know about my opponent. How many hands do you think is necessary to have aclear picture about someone?

It depends on the stat. I think for VPIP, 100 hands is more than enough and will get you within a few % of a persons true VPIP. PFR is a different story and I feel it starts becoming closer to accurate after a few hundred hands, say 300 - 500. For stats such as wtsd% and w$sd i don't like to trust them TOO much unless i have a big sample, over 1k - of course if someone has a wtsd of something like 4% over several hundred hands, you can be fairly confident that they're weak/tight. I rarely look at the bb/sb steal stats as i don't think it's that important in NL, it might be in limit though.

Agree with that, and as for win rate, well...you just can't trust it. I have 25K hands on someone who plays 100NL full time. He went bust a couple of weeks ago. My PT shows him at 5PTBB/100.

Any semi-pro going bust deserves to - if a full time player can't follow simple bankroll rules then he has no business playing poker...
