I don't play at carbon. Good luck getting a check when you withdraw, I've heard people having huge problems withdrawing from carbon.
You need to read the site. I believe PokerStars
started all the points stuff a few years back. And many of the sites that offer that run it much like PokerStars does. So, I would assume the same would be true with carbon.
However, PokerStars just started doing fractional points not that long ago. If carbon isn't using fractional points, it might be hard to earn points playing only 10nl.
You need to go to carbon's VIP page and see how points are earned. If they aren't fractional and are dependent on a certain amount of rake in ring games, 10nl on carbon wont get you there, HU SNG's and one table SNG's would be the fastest way.
