I thought this sounded like a reference to folklore, maybe. Apparently it’s an old film - The Seventh Seal by Ingmar Bergman - or possibly a painting with a similar theme. (A knight wagering his life on a game of chess by the sea.)

Blonde guy with mismatched eyes shows up? Makes me think of Jarrett (Labyrinth), though I doubt a kid reading would get the reference.

And now the line about licking games, but to being too strong an opponent? I wonder if this is ‘Nick’ again under a different face. And now he knows what gave the kids an edge against him last time.
