Since Ai Ai beat the Interactive Diagram at its default settings, I raised the Interactive Diagram to 4 plies and tried again. This game ended in a draw by three-times repetition, as called by Ai Ai at move 60. Apart from that, the Interactive Diagram was ahead in material and might have won with better endgame play. Here's the MGS file from Ai Ai: ID4-vs-AiAi-Chess.mgs. At move 60, I let the Interactive Diagram, which had been playing White, continue as Black, and I took over as White, eventually checkmating Black.
