Name: Yatahay / Winning Poker Network
Sites sharing network:
Although very few poker players indeed have ever heard of the Yahatay Poker Network, they have been around since the early days of online poker. They recently have rebranded it as the Winning Poker Network, a name that's certainly more friendly.
One of the things that this network has going for it, aside from its tremendous staying power in spite of not being well known, is the fact that they have always taken players from every country including the United States, and still do.
The flagship sites here are True Poker and America's Cardroom, which has also been around for quite a number of years.
