In their own words

1. The first illegal move

   Cohere: North Mini Code (free) tried Nd4 on move 3, which was illegal: no legal move in this position matches 'Nd4'. It played Rb8 instead.

   … No. Let's see white's legal moves after Nd4. We should check board after Nd4 (if we move). So let's simulate making Nd4, then get board's legal moves for white to see what threats we face. I made an illegal move because Nd4 is not available - the knight is on d4 already. I need to pick a legal move. Let me try a different pawn move or knight move. Looking at the legal moves: Nf6, Nh6, Rb8, a5, a6, b5, b6, c5, c6, d5, d6, e5, e6, f5, f6, g5, g6, h5, h6. I think Rb8 is a good move to develop a rook to the center, or a5 to open the center. Let me try Rb8 first.

2. The biggest capture

   Cohere: North Mini Code (free) took a queen with Bxd6 on move 17.

   … However, the bishop could still check, and the queen is still attacking. The b8 queen could also cover the escape squares. Actually, let me think more carefully about the position. If black plays Ke8, the king moves to e8 which is still on the back rank, but that square is attacked by the bishop on f4. Bxd6 looks reasonable - the bishop can capture the white queen on d6, removing the checking piece. This would be an amazing move that would turn the tables. Kdxd6 or cxd6 don't make as much sense. So Bxd6 is the best move. Let me play that.

3. The end

   Cohere: North Mini Code (free)'s last turn on move 28 ended the game without a move.

   … Already we think it's black's turn. We'll ask get_board. Looking at the position, black is in a lost position: - White has more material (balance -1 for black) - Black king is exposed on d8 with no escape squares - White has a rook on e5 and bishop on b5 targeting black king - Black queen is trapped on d5 - White has potential mates like Qe6+ then Rxe5 and Nf6# - Black is missing the bishop that was traded earlier This is a hopeless position for black. The pragmatic thing to do is to resign to stop further material loss and time wasted.
