For the next game, I gave the Ludii player 30 seconds of thinking time. It still played very poorly, making lots of obviously bad moves. The Interactive Diagram made sensible moves for most of the game, but during the endgame, it failed to mobilize its overwhelmingly superior forces for checkmate. It could have easily gotten checkmate by moving out a Rook to help the Queen, but instead it moved out its King. When it was getting close to further hemming in the King and eventually getting checkmate, it moved its Queen to a rank further from the King, giving it more space to move. Eventually, the game ended in a draw through three-times repetition, which I estimated by observing the same set of four moves repeat three times. Here are the moves:

  1. d4 e6
  2. c3 Qh4
  3. Nf3 Qe4
  4. Nbd2 Qf4
  5. Nb3 Qe4
  6. Nc5 Bxc5
  7. dxc5 d6
  8. cxd6 Bd7
  9. dxc7 Ne7
  10. cxb8=Q Rxb8
  11. Be3 O-O
  12. Qxd7 Qc4
  13. Qxe7 Rbd8
  14. Qxb7 Rd6
  15. Qxa7 e5
  16. Nxe5 Qh4
  17. g3 Qe7
  18. Qxe7 Rd5
  19. Bg2 Rxe5
  20. Qxe5 Rd8
  21. O-O h6
  22. h4 h5
  23. Qxh5 f6
  24. Bd5 Rxd5
  25. Qxd5 Kh7
  26. Qh5 Kg8
  27. Kg2 Kf8
  28. Kf3 g6
  29. Qxg6 Ke7
  30. Bc5 Kd8
  31. Ke4 Kc7
  32. Qxf6 Kb8
  33. Kd5 Kc8
  34. Qf5 Kc7
  35. Qf4 Kc8
  36. Qf5 Kc7
  37. Qf4 Kc8
  38. Qf5 Kc7
  39. Qf4 Kc8
  40. Qf5
