In their own words

1. The first illegal move

   NVIDIA: Nemotron 3.5 Lightning (free) tried Nf6 on move 5, which was illegal: no legal move in this position matches 'Nf6'. It played O-O instead.

   … That's bad. So Bxf7+ is not a good idea here. Let me think about other strong moves. Castling O-O seems very natural to get the king safe. Then I can continue with development. Or I could play Bd3 or Be2 developing the light-squared bishop. Actually, looking at the legal moves, O-O is available. Let me play that. Wait, but I should think about what's best strategically. In the Italian Game with 4...Be7, White often plays 5. O-O to castle, followed by Re1, or sometimes 5. d4 challenging the center. Let me play O-O for now.

2. The biggest capture

   NVIDIA: Nemotron 3 Ultra (free) took a queen with Nxe2+ on move 14.

   … Let me see: if Nxe2+, white king on g1, queen on e2. After Nxe2+, white can take with Kxe2 or maybe there's a piece defending. Let me check: white has rook on f1, bishop on c1, rook on d1. The queen on e2 is defended by... the rook on d1? No, d1 to e2 is not a straight line. The bishop on c1? No. The rook on f1? No. The king on g1? No. So the queen on e2 is undefended! Nxe2+ wins the queen! Wait, but after Nxe2+, white king can take on e2 (Kxe2). But that's still winning the queen for a knight. That's a great move! Let me verify: Nxe2+ is listed as a capture with check. Yes! That's the move.

3. The end

   NVIDIA: Nemotron 3 Ultra (free)'s last turn on move 66 ended the game without a move.

   The game is clearly lost for white. I have only a king left, black has king, bishop, and 5 pawns. The position is completely winning for black. I should resign
