The strategic game of unfriending people on Facebook. The pawns are the first to go...people who will never notice or give little resistance. After that you have to carefully plan your next step on who you will delete. Family members and crazy friends are much harder to delete and require a few steps ahead of planning.
I had a game of Facebook Chess the other night. I deleted all those people I added when I was in rehab that I will never see again, however, I plan on deleting my mother-in-law from facebook, this might take a few sacrifices.
