I sacrified my queen but, didn't get brilliant ??

I sacrificed queen but didn't get brilliant, either because I might have won materially or something

You had mate in one anyway.

mate in one step where do you calculate it? from my queen eating rook or before

Probably because it's a mate in two, and not a mate in more or a great way to win material

Rd1 would be easy checkmate without "sacrificing" the queen. Brilliant must be usually a unique difficult move with no alternative.

I did not see that you captured a rook.

yes, taking the rook with the queen is too easy to see, it is a forced checkmate, maybe in the tactics puzzles the rating would be not very high for such a pattern

There was a rook on f1. OP posted the full game above.

It's not brilliant because you had mate in 1 with a rook move instead of the queen. Either rook to Rd1 or Re1 would work.

Both of your sentences are false. Good job.

you know exactly how this is meant

Have a nice day

I believe the piece you took was a rook. It’s not a brilliant because if you didn’t take it you would still be up a rook. Brilliant moves are classified as moves that are sacrifices that lead to good positions but wasn’t in a really good position in the first place

apparently being up a rook is “really good position“

Strictly speaking, it is utterly amazing how you can be so wrong almost every time you post!

Many of the simplest chess puzzles involve queen sacrifice. Queen sacrifice in and of itself has no positive correlation with brilliance.
