Sorry it is a bit easy.
A puzzle of a trap to the black queen.
So, I don't see the trap. Black seems well protected.
Black are well protected but if you play live the player who play black may dont see that he has chance to save the queen. Anyway it doesn't matter since white has only a queen, a chessman and the king and black has too rooks and a knight. In the end of the game it will be the same thing: Black Wins.
That's a trap to the black queen that if I did it I would win a game that I lost.
