Janus Chess on Game Courier

Here is a selection of presets for playing Janus Chess on Game Courier. Click on one of the buttons below to choose a preset. Each preset enforces the rules, and each can spot check, checkmate, and stalemate.

If you find any bugs in the routines used for enforcing the rules, please report them to Fergus Duniho.
