Just go to the player profile. Below the name/location should be your w/l/d ratio.
I don't know 100% if it is available to basic members but that is where is located for me. You can click on that to get a list of the games, though that may be limited by a basic membership to the last 30 days.
I have been playing a friend (matgray) and I would like to know the overall score between us. I can only see the last 6 games we have played. How can I check the overall games played against him? Thanks, Pete
