I have been playing 6 max, where I 4 table, and have just started experimenting with HU. I started with 2 tables and found myself missing a lot of value in certain spots. I also started to give off timing tells I believe. So anyway, I am going back to the old 1 table until I get more hands in.
How many HU tables do you play?
How many did you start with?
1-2 is the magic number for me. With omaha being such a post flop game I think its real hard to play more than that without hurting your winrate significantly.
