Yeah it's slightly tighter play at $5NL but not by much it's just more money put in. If you're going to buy in for $10 then play $10NL otherwise you'll just be looking for another deep stack to play against.

Just put it this way, you're be making more than twice the money you were before at $5NL. Micro's right, don't play outside your BR.

And don't worry about that blog. Spend your time playing poker, you can post on your breaks
