Driz's Doubles Chess

Two teams. One board. Both teammates move at once - in secret. Sit at an open table or meet friends at a private one. No accounts, ever.

Doubles Chess is four-player team chess: two teams of two, one board, and both teammates moving at the same time — secretly.

Each player commands one half of the board (files a–d or e–h). Every turn, you and your partner each pick one move in secret; they execute simultaneously. You can see THAT your partner has locked something in — never what — until both moves hit the board at once.

RULES BUILT FOR SIMULTANEITY • The first move submitted locks in; the second must make the combined turn legal • Escape check as a team: one saving move is enough, judged on the combined result • Two enemy pawns can double-step in one turn — double en passant is real • Pins are real: you play the board as you see it • Checkmate only when NO pair of moves saves the king — strictly harder than normal mate • Pieces that cross the center line change hands: gifting your partner a rook is a strategy

PLAY IN SECONDS • Create a room, share the 4-letter code, friends join instantly • No accounts, no sign-ups — pick a name and play • Empty seat? Add a bot with engine-ranked moves • Disconnected? Reconnect and pick up exactly where you were • Resigning takes both teammates. A draw takes all four. Argue accordingly.

Bring your favorite partner. Blame them later.
