Everyone versus the engine.
One move a day, chosen by whoever turns up. The move with the most votes gets played, and Moonforge answers.
Every legal move is on the ballot, so the community can play anything the rules allow — not a shortlist someone picked. One vote each, and you can change your mind until the deadline. Nothing is stored about you: your browser gets a random name the first time you vote, and clearing your site data throws it away.
