Guess I am the only one playing UB still. Shame on me but the games are so good. The hand histories have changed quite a bit due to the seven deuce prop bet.
My understanding is that PT3 already supports ring games that have antes...at least for FullTilt I know it does, I don't know specifically about UB/ABS but I would guess they support it. This is something to ask on the PT3 forum for a definitive answer.
