> Top engine move changes with evaluation time I think that's like saying you can't play scrabble because the dictionary changes over time. You specify the engine and wait time before you start a game.

You can't. You have to share the best move ahead of each move. Waiting for a specific duraion may yield different results depending on CPU usage or other variables.

Players only reference the engine to resolve a claim, after the move has been played.

"" If the chess engine suggests the opponent’s move, the claimant wins the game. If not, their opponent wins instead. "" How? Top engine move changes with evaluation time. Longer the wait, better the move.

You can make the engine choice deterministic just by choosing an evaluation time and settings.

Where time is measured in the number of positions evaluated.

That actually looks hilarious, especially the part where checkmating is illegal since it would always be the best move. The first game highlighted is also fun. I'll have to try this next week at the chess club!

Should that always be the case, though? We could try to force a position where 2 separate moves checkmate. Then only 1 (presumably the one that results from capturing the highest valued piece?) would be the engine result.

If you can check your opponent, giving them only one legal move, you win (because it is the top engine move).

Ah. So part of the fun is not knowing which move is forbidden, ahead of time.

Is this called "Human" chess because top engine moves would not be humanely possible?

I have a low chess rank (900 on chess.com), yet on an okay game 25% of my moves will be "top engine moves": https://i.imgur.com/TGaDtzr.png

I could even easily find games where I had 50% of top engine moves.

It's really not exceptional. Often the top engine move is the only good move and that only good move is pretty obvious.

With this variant you can win without checkmating: just checking with leaving only 1 forced move is enough to win the game.

A simpler variation, that needs no computer to settle disputes, is Veto Chess. In Veto Chess you get one chance per game to veto your opponent's last move, and force them to make a different one. This shares with Human Chess the property that you can win by checking the king such that the response is forced. It may also serve as a handicap system in games between players of widely different strength, where only the w…

I expect that if I were offered a veto against a stronger player, I would not be skilled enough to spot which move to veto, and would probably end up hoarding my veto, like in video games where you have a great-but-rare ability that you keep perpetually in reserve.

But then, I’m a terrible chess player.

Now: Human Chess: a variant where you can't play what AI would play. Next: AI that can play Human Chess. After: Human^2 Chess: you can't play what the AI above would play. etc I wonder if this creates distinctly new games at each level, or if it's just nonsense one level down.

I loved the idea, but on further thought, the AI has a huge advantage in knowing what the engine move is, so they can never lose to incorrectly calling the last move and engine move.

This is explicitly addressed: When multiple moves have the top score, they are all top moves,

I wonder if a move that checkmates is scored lower than a move that checkmates and captures.

Checkmate .. with advantage!
