The move I made that I did not know it was brilliant!!!

Why is Nd5 brilliant? I've been calculating and I don't see the idea

no idea (IDK)

https://www.chess.com/analysis/game/live/123013461462?tab=review look at this i made 6!!! great moves but with 3 blunders

with the night blunder i miscalculated something

same with the bishop and again...

"Brilliant move" means: a sacrifice that is good.

This Nd5 move is not a sacrifice.

So either they changed the definition again, or it's a weird bug.

I'm new here, but I guess since the opponent has to either move his queen or take the knight and if he takes the knight he loses the queen anyway to the bishop.

But sometimes the analytic is rather strange IMHO, I had a puzzle where I took a Bishop with a rook and was going to lose the rook anyway better get some value for it, but the "correct" answer was to take a pawn - though it was in front of the king, there were no pieces ready to take advantage of it, so I didn't get it. We should be able to rate those, or flag them for errors.... maybe there's some GM-thinking behind it that I'm not capable of, and I accept that..

yoo i just made a brilliant move i dint know,i thought it was blunder
