My brilliant move

Here is the game position. What was my "brilliant" move? (Upvote if you liked this puzzle and want me to do more!) Also share your answers in the chat!

Had to update! (Was one move ahead)

Rook to d1 , trade rook, trade queen , checkmate

Wrong!

Na4!!, the point being that if Rb8, then Rc1! If Qxb7, Qxb7, Rxb7, Rc8+, winning the bishop AND rook.

Wrong! Na4? Allows Bxe4.

I give up. I spent some time too.

Bxe4 doesn't look that strong.

But it does lose white's advantage.

DM me for the answer

Correct!

why is Rac1 so important

Why can't you also do Rfc1 lol

Stockfish says Rfc1 is a blunder.

Beautiful! I considered it, but I couldn't see the follow-up.

The point is that after bxc3, Rxc3 followed by Rc8 gives white great chances to promote.

I see. Very instructive! Thank you!

And if Qb8, Qc6, right?

And I would like more puzzles like this, please.

Sure!

I think so!
