John is not very chess-literate, he doesn't even know about checks! He gets his own king captured because he isn't aware he has to move it. He doesn't know about the en passent, the promotion, the castling... He's just in it for the fun.
Ooh, hello there rookie

Launch this file for pure unfiltered fun against your friends in a 1vs1 on the same device! I love John Chess!
My implementation of "John" within the game. Launch this file instead if you want to play against the John Chess highest-rating FIDE classified Grandmaster.
No checks, no castling, no enpassent, no stalemate, no 50-move rule, no threefold repetition, no promotion.
Only pure unfiltered fun.
You win if your king is captured! Good luck!
"The game say "Black wins!" when you're playing white and you get your king captured. That's a bug, probably" - John
John can be whoever you want. Maybe John is a cool sub-urban guy in his 30s who takes serious interest in chess, or a 14-year-old who only enjoys playing video games and eating snacks, or a man who's been a professional chess player for 30 years.
It's up to you, that's the most beautiful thing about John.
