Some fun puzzles :)

Hey everyone! 
I would like to share some interesting puzzles, with some nice tactics.
I hope you enjoy!

On the second puzzle Bxh2+ first is still better for black

yeah that's true, I don't fully understand why the engine evaluates that so high for black as you only win a pawn and not a pawn and an exchange after exd3 cxd3 Bxd3 Qf3 Bxf1

I picked these from some of my games where the engine considers these sacrfices brilliant moves, so it's possible that there are other variations that are still better/winning for black though the puzzles require you to play the best moves

Nice puzzle
