I don't have a positive rate of return but I normally play double or nothings. I do OK in that format. I just need to remember to slow down when I get to a nice amount in chips. The games always end with a stubborn short stack who refuses to lose into they run out of chips. (sometimes that's me.)
I play normal and turbo sit and goes but the turbo games do progress a bit faster than I am used to. I would need to adjust somewhat. As for the amount of tables I tried playing 3 or 4 tables in the past but I don't think it works out for me currently so I probably would just stick to 2 or one table.
has a sit and go leader board and man! I cant believe how many games people play. Its been two days and people have played over 60 small stakes games! I put in bigger volumes some days myself though. Playing sit and goes seem like my only hope to make any money in poker because I am not a good ring game player.
