My colleague Prof. Dr. S. writes a fictional story with symbolic elements involved. One of them is a simultaneous game played by a grandmaster with a gifted schoolboy. Prof. S. wants to represent it by a real game by players of similar strength. But for some symbolic reasons, unknown even to the author, :-) the end of the game must match the following pattern. At the final stage Black finds a unique saving move ... Nf6 and after one move White has nothing better than a perpetual check. I failed to find such a game by Google and I am not acquainted with chess databases, so I ask here for a game instance matching the given pattern, preferable with mentioned strength of the players. Thanks.
Update (May 7). I have a talk with Prof. S. He thanks to all who offered help. Below are results of our discussion of the problem conditions.
The move …Nf6 followed by a perpetual check is a necessary game condition. But between ... Nf4 and the start of the perpetual check (which we consider as the first check in the series) are allowed a few intermediate moves, preferable at most three (at most four in the worst case).
Prof. S. understands how hard is to find a required game and thinks that it is needed a lot of luck for this. If it will fail than then, as already proposed @Brandon_J and @Scounged, there is an option to construct a fake game of sufficiently strong players (especially White) which satisfies the above conditions and does not looks artificial. In this case it is preferable to start a game from a move 1. d4.
On the very worst case when even a construction will fail there is a option to construct only the final position, which looks as a plausible position from a game of sufficiently strong players.
Unfortunately, the game between Ward and Lalic does not fit the purpose of Prof. S. He needs a material advantage for White which is kept after the move …Nf6. Nevertheless, also is required that this move is not an obvious, and this is a problem. The advantage, the bigger the better, but it can be sufficient for White to have a superfluous or a passed pawn. The aim of this condition is to provide for the amateur audience a game position which seems to be winning for White.
