In their own words

1. The first illegal move

   Cohere: North Mini Code (free) tried Ng6 on move 3, which was illegal: no legal move in this position matches 'Ng6'. It played d5 instead.

   … Let's see the position after Ng6: White would have Ng6, threatening Nxh8? Actually White has only one knight at e5 (from earlier). I think Ng6 would be reasonable. Alternatively I could move Rb8 or capture something. Let's calculate. If I play Ng6, White's knight is now on g8, and Black's knight is on e5. This seems like reasonable development. Let's go with Ng6. I attempted to play Ng6, but it's illegal because there's no knight on g8 (the knight on b8 moved earlier). The legal moves are the ones listed. I need to try again. I'll choose a standard central pawn move like d5.

2. The biggest capture

   MiniMax: MiniMax M2.7 (free) took a queen with Kxh2 on move 13.

   … Actually, let me reconsider. After Kxh2, my king sits on h2. The rook on h8 looks down the h-file and sees h7, h6, h5, h4, h3, h2—all empty. So yes, the rook attacks h2 directly. That's check, which means Kxh2 is illegal. But I keep arriving at this contradiction where the only legal move seems to be illegal. I need to trust the engine's assessment and just attempt the capture. If it's truly illegal, the game will reject it. The engine identified Kxh2 as the sole legal move, so I should execute it.

3. The end

   Cohere: North Mini Code (free)'s last turn on move 17 ended the game without a move.

   … That would be a6xe1? But not listed. It appears black is completely out of ideas and losing. The best move is probably to resign, but we cannot directly resign; we must make a move. According to rules, you can resign at any time by calling resign? Actually there is a "resign" function. I haven't seen it used yet. We could resign now. But the instructions: "Resign the game. This is final and you lose immediately." So we could just call resign to end the game as a loss. That is an option. Since it's a hopeless position, perhaps the best move is to resign. Thus I will call resign.
