Exercice to begin the week

What is better before going to work that resolve an exercice?
Question 1: here 1.Qh7 + win please write the winning variation
Question 2: 1.Rd3 wins  too write the winning variation
Question 3:there is another win ,I would say more aesthetic(to me at least)can you find it?(move and variation of course)
Try to find the more variations you can but do this without moving the pieces like in a real game.
Nothing to win except a kiss from the editor if you are a girl
Solution next Saturday
Have a nice week!
