1) Online Chess-love playing without time pressure
2) Vote Chess

If I am at home, I go nuts if a whole day has passed and I haven't played chess. The only way I can avoid the game is to go to the woods. To tell you the truth, though, even that can fail. I played a couple of games on my phone last spring while sitting in my blind looking for turkeys.
I'm even older! It was ++ in my days.
My first chess application had ++ as a symbol for mate.
