Can I watch a game that I'm not playing in?

A. Almost every site lets you do this, so, yes you can. It's a great way to watch how people play and perhaps add more to your game. Also, as you're thinking about moving up in levels, you can watch how people play at the next level to determine whether you believe you are ready for it. Not to mention that it's always handy to try to guess what hands people have and why they played it that way - and what better way when you don't have to worry about your own hand?
