Threats

I like how much you guys like chess puzzles so I figured why not give you a chance to do some. All of the following should be threats

What is the threat black is pulling? and can you checkmate black in one move? In the comments please type 1. then you answers

What is the threat white is pulling? and can black stop the threat? Answer in the comments by typing 2. then your answers

That's all I have today, please check out my news feed Chess Inc. News and See you soon! 

Thanks all
