I really enjoy HORSE for the most part. Razz is one of my stronger games which I suppose helps. I'm no expert but I'll toss out a couple of things for what its worth.

1. Be careful in the early Hold 'em and Omaha H/L rounds. Everyone seems to think they are great at these games and it is easy to get in hands with 'too much action'. If there are two donks reraising each other max every street then I'm only playing the best starting hands and then the flop better hit me hard.

2. Don't play scared in 7 card stud. If no one raises in the first round and you have position then pay to see a 4th card. It only costs 1.5x the ante. Also, a lot of players will bet after 4th street with air and then back off.

3. Pay attention to the blind/ante structure. I play mainly at Stars and after the first two rounds the blinds/antes get so large it is sick. This makes stealing so profitable that you have to try it.

Good luck on the felts!
