In their own words

1. The first illegal move

   Cohere: North Mini Code (free) tried d5 on move 3, which was illegal: no legal move in this position matches 'd5'. It played Bc4 instead.

   … Also queen can go to e2, f3, g4, h5? Wait f3 is occupied by knight. g4 is free, h5 is free. Common first moves after 1.e4 Nf3 are: Bc4, Nc3, Nf3 again, d4, etc. I already played Nf3. So good moves are Bc4, Nc3, d4. Since black has a pawn on e5 attacking white's e4, we should develop the bishop to c4 to cover that square and develop to a strong diagonal. Or play Nc3 for symmetry. Or d4 for central control. Let me think: Bc4 would develop quickly, take the c5 square, and cover e5. That seems good. Let me try Bc4.

2. The biggest capture

   Dots Studio: Dots3-Note Preview (free) took a queen with hxg6 on move 12.

   … So black loses two pawns, gains queen and rook. Net +9+5-1-1 = +12. So black would be winning big. But is there any trick? After 1... hxg6, white might not play Rxf5 but something else? White could play Qxg6? No queen is captured. White could play Bxf5? No bishop on g1 cannot reach f5. White could play Nf3? Knight on g1 can go to f3, but doesn't threaten. So best is Rxf5. But then gxf5, black is up a rook. So hxg6 seems winning. Alternatively, Kf8 or Ng7 avoid capture of queen but remain down material. So hxg6 is best. Let's play hxg6.

3. The end

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

   … However, I should continue playing to see if there's any chance. Let me think about what White's options are. From the legal moves list, White only has: - Kh1 - Nb4 - Nb6 - Nc3 - Ne3 - Ne7+ (check) - Nf4 - Nf6+ (check) - Nxc7 - Rb1 - a3, a4, b3, b4, c3, c4, d3, g3, g4, h3, h4 Let me check if any of these make sense. If White tries to capture the rook with Nxc7, that would just give Black the queen back. If they move queen to some squares, they'd still be losing material. The position is hopeless. I should resign.
