Hey--Welcome to FTR. My advice is to use FTR's resources as much as possible. Particularly, you should post hand histories whenever you have a question about the right play, and critique other people's HHs. I think analyzing HHs has done more for my game than anything else. Once you get to where you reflexively think situations through instead of just going with your gut, you are ahead of most players out there. Maybe you're already there, but I know I wasn't.

My other tip is to learn how to fold when you know you're beat.
