This is a match between me and the commenters. Resolves Yes if I checkmate You. Resolve No if I am checkmated or the game ends with a draw. I will not bet. 

One rule is added to the chess ruleset (it consists of two sentences, the second one is just elaboration). 

The rule is "fair": it doesn't give advantage to any side, is symmetrical, does not depend on the move index.

The fact that I know the rule and others do not is the unfair part of the game. Commenters are encouraged to discuss and try to find out the rule during the game. Commenters are allowed to use programs and help from people even outside Manifold, and I am allowed none of that.

After each my move I will comment with a picture of the current situation on the board. Team of commenters makes a move, when one makes a comment with the move description (similar to 1:Qa1-a2) and it recieves 3 likes from others. (My likes do not count, so I can't sabotage). If the move is illegal, commenters recieve another chance to make a move (unlimited). There is no time control. But i will try to make my move within 3 days. Closing date might be prolonged, do not take it into account.

To prove that the rule is created before the market, I've created a github private repo with the rule commited today, which i'll make public at the end if needed.

+Upd. It was suggested to post a hash of the text containing the rule. MD5: 4f17d1b553afe8f7ffeb8cd88b6f2e8b

+Upd2. If you are not planning to commit a move to be voted on and just want to test legality of several moves, you can write up to 5 moves in a single comment.

+Upd3. The legality check is changed. From now there are "3 potential moves per person per game move" commenters can check. This is made to prevent spam and bruteforce.

+Upd4. To overcome the "like bug" now to show that you vote for a move to be made, make a comment under the suggested move, start with "+vote ".

+Upd5. I don't want the game to be frozen, so i introduce a new mechanic. After each my move i will tell in the comments 4 valid moves for white: one best, one worst and two mediocre. But that is your job to understand which is what.

(I still do not use computer help, all 4 moves are evaluated by me)

You DON'T have to choose one of these four, you can still do legality checks and propose your own moves as previously.

+Upd6. "4 named moves"  and "legality checks" are disabled due to the change of the nature of the game.

I had a peak of 1800 Elo in Lichess classical time control around 4 years ago I think.
