For some odd reason I'm searching for a game, or rather a position, where one player can force a win via checkmate (can be check in n, where n is any number), but they can also force a draw via perpetual check (again, maybe the perpetual check comes about a few steps later, but the player has an assured path to it).
A real, historical game would be a bonus, and a game between two skilled players will be even better. But constructed positions, even weak ones, will be appreciated, too.
