Manifold plays white.

Kongo plays black.

Predictor chess.
The game mechanics benefit the player, who predicts opponent's behaviour better.

0. Predictor chess is played with the ordinary chess set: 8 by 8 field and 32 pieces.
1. Game is divided into ply. Each ply is a game state, achieved after simultaneous processing and execution of both players' orders.
2. Before each ply eligible players commit a rule. (In this market black publishes their encrypted move first). The message contains primary and conditional move.
Primary move is a familiar ordinary move. Example: e2-e4.
Conditional move is a set of a) prediction of what the opponent's primary move will happen at the same ply, and b) how to respond to that. Example: if e7-e5 then Nb1-c3.
Conditional move Path cannot be occupied by a piece before the new ply. (You cannot order a classical capture with a conditional move.)
3. Path is a set of all the squares the piece visits when executing its movement, including the target square and not including the starting square. We say that all pieces slide, visiting all squares inbetween. Knight cannot jump over pieces, it slides in a Z pattern.
3.1 We say that paths intersect if they share at least 1 common square.

4. Move orders are processed the following way:
4.1 Primary moves are added to the set of moves to be done (MTBD). Conditional moves are added if their prediction was correct. This always results in a set of length [2, 4] inclusive.
4.2 If pieces attempted to capture each other, both are annihilated and their moves are substracted from mtbd. At this point mtbd might have a length of [0, 4].
4.3 For each move from mtbd draw its path on the board. If different color pieces' paths intersect, both are annihilated and substracted from mtbd. If there are several intersections, (for example, your conditional move crosses both primary and conditional move of your opponent, or all 4 pieces cross a single square) then all the associated pieces are annihilated.
4.4 At this moment only independent moves are supposed to stay in mtbd. All the pieces which are left execute their movements/captures.
4.5 All 4 moves and both predictions (even if incorrect) are highlighted on the map and the new ply is published.

5. If not stated otherwise, normal chess rules apply.

6. En passant can be only performed as a conditional move to the current opponent's primary pawn double move.

Elaboration:

1. Capturing a rook in a long castling does not affect the double-move of the king. (0-0-0 Rb1 will result in both rooks being annihalated and a king standing on c1.)
   
   Market Management.

1. Buy Yes shares to become an eligible white team player.

2. Kongo plays black and has to publish his move order first, cyphered.

3. When the time dedicated for a ply ends, I will look through commited moves and take the move from the highest shareholder from white team. If highest did not commit a move, then the second highest is picked and so on.

4. I will actively prevent sabotage and metagaming, even if I would need to contradict already established rules of the market and rewrite them.

5. Each ply (boardstate picture and most recent orders) will be published in the comments.

Recent update:

1. Added Elaboration 1 about castling.

2. Replaced "target square" with "Path" in rule 2. That change prevents discovered instant attacks.
