Resolved
YES

Christopher Randles plays as white, and if he wins this market resolves to YES.

Pat Scott plays as black, and if he wins this market resolves to NO.

In case of a draw this market resolves to 50%.

One rule is added to the chess ruleset.

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

The rule is unknown to the players at start.

Before making a move the player can choose one instrument:

1) Legality check. Name three 2-halfmove continuations of the game. I will tell which moves would be illegal in the lines. Example: "13.Ra4 bxa4, 13. Ra5 b3-b4, 13. Qb2 b3-b4" -> "b3-b4 after Qb2 is illegal".

2) Question. Ask me a question and I will answer Yes|No|NA.

3) Gamble. I will tell 4 moves available in the current position. One of them will be the best in my opinion, one will be the worst, it is not revealed which is what. The player does NOT have to play any of the four moves.

Any information is revealed to both players.

Time control will be added if appears to be needed.

Game is played in the comments.

The board picture in the description will be updated.

I think I was particularly slow to work out what the rule was, I didn't know until about move 19 and was strongly helped about then by a misunderstanding of what move I had played. I feel my initial strategy of mirroring Kongo's moves on the first game worked well for me. Pat pushed a bishop to g4 where it got trapped. So I was rather surprised when he move a N to the same square on move 11 where it also got immobilised. It was remobilised on 14 f6 so not really sure why Pat didn't save that knight even if it did mean moving it to a rather remote h6 so 17 b5 seems very odd.

I guess a game with two players who understand the rule from the start would look much more sensible, but I am not sure whether any players would be interested in trying that.

Anyway thanks for the game Pat and the refereeing Kongo.

@ChristopherRandles @Stralor sorry for my absence. As the judge, may I suggest the victory for Christofer? Pat has the right to fight though, if he wishes.

predicted NO

@KongoLandwalker fairrrr he's mastered the rule better than I did and I'm going slow. I concede

bought Ṁ10,000 of YES

@Stralor the result was going to be a long and slow stalemate which isn't fun for anyone

predicted YES

@Stralor I think I have enough mana invested to ensure I don't stalemate. 39 ... Kh4 speeds up the mate a lot ;)
But without such help I was getting to mate around moves 53-63

predicted YES

@Stralor So graceful. No losers here, we all won! 😉

Now the U.S. Supreme Court has spoken. Let there be no doubt, while I strongly disagree with the court's decision, I accept it. I accept the finality of this outcome, which will be ratified next Monday in the Electoral College. And tonight, for the sake of our unity as a people and the strength of our democracy, I offer my concession.

predicted YES

you probably want to extend the close date?
