I have done it in a chess puzzle before, but never in an actual game. Did anyone remember that puzzle from around maybe Sept-Oct that had you checkmate with a castle?

Here is the first time I checkmated by castling. Really proud of it!

here's how i unlocked the 'castle victory' achievement.

saw that in a puzzle but d2 was blocked which forced me to castle

Which begs the question are there some games that force you to deliver checkmate

i want that caste checkmate
