I constantly work with clients who tell me they are running bad when they are actually playing poorly.
How do I know they are playing poorly? I review their hands. They give me hand histories from their online play. I make them write down every hand they play live. What we analyze isn't pretty.
If you want to make a grown man cry show him all the ways he lost money in a particular session. With database management tools, you can show the person their expected losses based on their plays.
Do you think you have been running badly lately?
