Depth 18 Engine Says My Checkmate Is a Blunder?! 🤔♟️

Ah yes, classic engine behavior:
"You delivered checkmate... but not my favorite flavor of checkmate." 🍦♟️
🙂🙂🙂

that doesn't look like the chess.com platform - not trying to be rude or anything, but the engine wouldn't do that, the chances are mega low. you could have added the blunder symbol next to it.

No worries, I get where you’re coming from! 👌
However, this genuinely happened - not on Chess.com, though; you're right about that. It was on a different platform.
And yep, I double-checked - it flagged the checkmate as a blunder, probably because it preferred another mating line.
I was feeling happy.
Queen flies in — opponent’s king cornered.
Game over.
The position? Crystal clear mate in one.
Confidence: 100%
Reality: Completely wrong.
The engine says blunder?
I gave a checkmate, not a mistake.
Is the engine trolling me ????
