Vote chess
ruelasker wrote in a comment on a vote chess game: " In vote chess we are often disappointed in the votes of our colleagues. Sometimes we become glad that the team played a better move than we wanted to play, other times we feel that an opportunity was missed because our move was better than what was chosen. We have fun with vote chess and we learn many lessons about the game of chess in general and how players think."
Amen to that. I might add that in our own games we are often disappointed in our own moves (certainly when we review them a week later).
Vote chess is a lot about seeing how other people think in situations. It's not about winning so much as the game itself. As we say in bicycle touring "The joy is in the journey" -- and the destination is secondary.
