     (White resigned because the rook on h1 is lost.)

Here is the game in PGN notation.

The funny point is that the opening transposes from the English Opening into the Queen’s Gambit, and Black not only refuses the gambit, but instead plays its own one. So the MM5 neglects its development for going after pawns while the CT800 develops its pieces.

The white king stays trapped in the middle, which the CT800 correctly identifies as primary target. The CT800 keeps its attack going to prevent the MM5 from completing its development and from castling. The MM5 realises the danger far too late and cannot avoid massive loss of material, which the MM5 acknowledges by resigning.

The remarkable aspect here is that the CT800 beats the MM5 pretty much like humans would play against chess computers from that era, by relying on their material greed.
