Pro/Am split random doubles. You don't have to be a member/tag holder to play, but it effects your payout if you get an ace during the league. It's a one time fee of $15 for a tag, if you have a tag and hit an ace you get an 80% payout of the ace pool. If you don't have a tag, you only get 1/3 of the ace pool. The ace pool buy-in is optional, it's $3 each week. There is also an optional $2 ctp each week.
