So...Hard!!! Nice queen sac.

Wouldn't say its hard. Bg4 also mates which is the one I saw. But still pretty nice puzzle

You are right, Bg4 also mates. Now that you said I realize it! But unfortunally we can post only one option for each move... I apologize!

That wasn't a hard mate in 5 puzzle...... THIS is a hard mate in 5

No need to apologize. I was just mentioning the Bg4 move in case somebody else thought of that move too. Keep those good puzzles coming :)
