In their own words

1. The first illegal move

   NVIDIA: Nemotron 3.5 Lightning (free) tried e5 on move 5, which was illegal: no legal move in this position matches 'e5'. It played Nxe4 instead.

   … The position has: - White just played Be2 - Black to move - Move 1 Let me play e5 again to continue the open game. This is a natural and solid continuation for black. The e5 move I played earlier is not available now because the position has changed. Let me look at the legal moves and choose something reasonable. The pawn is on e7, and the position is different now. Let me pick a reasonable developing move. I'll play Nxe4 capturing the knight on e4. I captured the e4 pawn with the knight. Now it's White's turn. Let me see what the position looks like after this capture.

2. The biggest capture

   NVIDIA: Nemotron 3 Ultra (free) took a queen with Nxf6+ on move 12.

   … Black's pieces: king on g8, queen on f6, bishop on e5, knight on c6, bishop on d6, rooks on a8 and f8 (or h8? No, kingside castled so rook on f8). After Nxf6+ gxf6, the g-file is open for my rook, and the king is on g8 with weakened pawn structure. But I need to be careful about the bishop on e5 and the knight on c6. Let me think about this more carefully. Nxf6+ seems like a strong tactical shot. Let me play it. I played Nxf6+ which gives check. Black will have to recapture with the g-pawn (gxf6) since the king is on g8 and can't capture on f6. Let me wait for Black's response.

3. The end
