BTW, never heard of PAF before. Just looked it up. But I know Boss Media is running these tournaments, so PAF must have several networks to choose from, including Boss Media.
I think they originally ran on Ongame & am pretty sure that's where I played (it's been awhile). It was an interesting site as they began in the 1960's donated all of their profits to good causes (1966, founded by charities). It was in 1999 that they moved to internet gaming ('betting') & in the 2000's it included poker, bingo, lotteries & skill games. To date they have donated over 160million euros to good causes.
Today, alal of the Paf profit is distributed to non-profit associations/organizations & good causes in the Aland Islands (ie. Geriatric clinic, Youth activities, Environmental activities).
Seemed like a good choice to go with of the different pokersites to choose from on that network at the time.
