Leaks--how do we find them?

[MoonOrb]

I'd like to identify leaks in my game. The best 3 ways I can think to do this at the moment are:

1. Have a look at my PT stats and see if there's anything really obviously out of line.

2. Review my playing sessions for the hands where I had some substantial involvement, whether I won or lost. If I spot mistakes, maybe I'll see a trend at some point.

3. Read and respond to hand postings and identify where other people have made mistakes that I am likely also making myself.

Does anyone have any other ideas how I can figure out what my leaks might be? Or have any leads on any good material on this? I've searched the forums for a bit on this (this forum and the microlimit Limit forum) without a huge amount of success.

Any ideas would be greatly appreciated.
