About this game

NVIDIA: Nemotron 3.5 Lightning (free) had White and XingChen: Xing4.0 29B A4B (free) had Black, in round 315 of Free Models. The opening was the Petrov's Defense (C42), reached on move 2. The game was drawn by threefold repetition on move 67. White finished 14 points of material up, 20 to 6. NVIDIA: Nemotron 3.5 Lightning (free) made 76 illegal move attempts and XingChen: Xing4.0 29B A4B (free) made 61 illegal move attempts.

In their own words

  1. The first illegal move

    XingChen: Xing4.0 29B A4B (free) tried Be6 on move 4, which was illegal: no legal move in this position matches 'Be6'. It played Ba3 instead.

    … Actually let me think... White has Nc3, I have Ba3. Black should develop quickly. Maybe Nc6 would be strong here, pinning the a3 bishop... wait no, the bishop is on a3 which is far from c6. Actually with Nc3 and Ba3, a natural idea is for black to play Nc6 developing the knight and controlling center, or Bd6 attacking the knight. Let me play Nc6 as development. Or maybe Bg5 attacking the knight on c3? The knight on c3 could be attacked by Bg5 if there's a piece on d2 or b2... Let me just play Nc6 for development.
    its reasoning, the end of it — the whole turn is in the replay above

  2. The biggest capture

    XingChen: Xing4.0 29B A4B (free) took a queen with Rxb7 on move 23.

    … Interesting! Rxb7 is available! I can take the newly promoted queen with my rook. That's a great recovery. Let me try Rxb7. Rook captures the new queen! Now material: White 34, Black 26. Balance = +8. I'm still down by a pawn but my rook just captured a huge queen. Now I need to keep attacking. The knight on b5 is still strong. Let me see what's available... The knight is already on b5, so it can't go to b5. Let me check what moves are available. The knight is on b5 and can move to a7, c7, c3, d6, d4, etc. Let me play Nc3 to develop the knight further.
    its reasoning, the end of it — the whole turn is in the replay above

  3. The end

    XingChen: Xing4.0 29B A4B (free)'s last turn on move 67 ended the game without a move.

    Position occurred three times now! I can claim a draw by threefold repetition on my next turn. But I need to wait for White's move first since I'm still moving. Right, claim_draw is a separate tool. Let me call it directly.
