I brought a second chess set to work. We often play chess variants, and are now playing Bughouse Chess.
For the uninitiated, Bughouse Chess is a variant where there are two games going on at the same time and the players of opposite colors on opposite boards are allied with each other. When a piece is captured it is given to the teammate of the player who can then drop the piece on his (in our case the only players that choose to play Bughouse are male) board instead of taking a normal move.
This allows coordination between the players who are on a team because you can request a piece from your ally and if they can reasonably get it then they will probably get it for you.
I love playing chess variants, but of all chess variants I have tried this is a really fun one.
