I originally wanted to call this Pièce touchée, pièce jouée based on the chess rule that once you touch a piece, you must play it. But the server doesn't allow for French accents in titles.
This is a trend that I hope will keep going. Ottawa needs a lane of culture and intellectual stimulation from other than the national museums.
Chess is like playing hockey really, really slow. I love playing but I'm not sure I could enjoy it on the street like these people do. I need to be in a quieter, less distracting setting.
