A tactical move...

... to win a piece

On material count both players have 18 points. Black's two rooks and bishop are a good match for White's queen and rook.

However, on this move White can gain a significant advantage as there is a weakness in Black's position.

😙  Can you see the winning move ?

I set up the position on the Chess.com board and played against the computer (Level 8)

It took me 33 moves to checkmate Black's king. You might see a quicker way to finish the game.
