I play single table SNG's. Maybe a few of them every night before bed, like two or three, or maybe 10 heads up sng's.
For me I think I do better with this approach. I've been playing poker recreationally a long time and over the past few months I've been a winning player for the first time ever (About a 20% ROI on small stake sng's, I used to play pretty much only cash).
It used to be that I'd get back into poker every once in a while and play every free minute every day eventually going busto. Now it's more when I have time and when I really want to play.
Nothing wrong with playing alot more than I do, it's just not realistic for me due to family and work etc, and I also think I just don't have the mindset of a good pro poker player. I get too emotional after bad beats etc, so me playing a few SNGs at a time is good because if I get angry it's not affecting my next game because might not be til tomorrow or the day after.
