It would really depend on your limits, table structure, rake structure, # of people at the table and amount of action.

The only place where you can make a profit by just sitting and folding would be at the .5/.10 tables at FT......and even at those tables there is often not enough action to make this happen. You have to stick to the craziest omaha tables. But if you do the math.....

9 handed table
.5/.10 blinds
10% rake
once the avg. pot reaches about 5.50 you will be making about what you need to cover blinds.

rake does not increase proportionally for the most part as you increase limits...so if you sit down at the $400-800 NL table...you're not going to become a winning player by getting rakeback setup
