Help wanted

Hello all.  I am writing a novel and there is a chess element involved.  In one scene, the player, who is IM level, is playing a mysterious opponent over the board who nevertheless seems to be using a computer to plan his moves.  I have seen discussion from high level players about "machine moves", or moves that a normal human would not make or even really understand very well that nevertheless spell victory for the computer. She will come to see her opponent's moves in this way.

I thought it would be fun to include the actual text of the game, for those who might read the story and know something about chess.  It's not really necessary but it would also help me describe their play.  

I am wondering if there are some good examples of such games that I might borrow from, or perhaps even someone here who might enjoy creating such a game using a chess engine.  I am simply not a good enough player to be able to create a game that would have this characteristic or really even understand such a game. There should be one or more moves that just leave her puzzled until she can get home to her computer to replay it all.

The game is not at a tournament, just in a park, so how and why her opponent would do this will leave her quite puzzled.

If someone would like to create such a game, with explanation of which moves an IM level player would be able to spot as machine moves and how the moves ultimately allow her opponent to win, I would be very grateful.  

Happy holidays to all, and thanks for listening.

You could just use the game Kasparov lost to chessgenius in the Intel Grand Prix in 1994. I bet there are annotated versions of that 'out there'.

B.Ivanov's game where he plays illogically, scattered on both sides of the board, but it culminates in deep tactics only possible from the obscure placement of pieces on both sides working together.

I wonder if someone will find it for me... I'll look for a bit. It's the most glaring display of cheating I've seen.

Moves 1-10 white is developing queenside ideas. Move 12 is accurate but difficult, but then boom, moves 13, 14, 15 make no sense in context with the previous play, but are very strong and justified by deep tactics that don't appear until 10 or so moves later.  Now pause at move 18, wow, white is scattered across the board, and pressuring everywhere at once. This (and the justification that follows) is inhuman. Pure calculation, no logic.
