Mate in 2

Puzzling Puzzles consists of 12 puzzles, all following a certain theme. Part 1’s theme is Mate in 2. I hope you enjoy these puzzling puzzles! (Note that sometimes you put in something that leads to mate, but it says that the move is wrong. That means there is more than one solution, and you’re trying to find that one. Also, after you solve a puzzle, you can see all possible checkmates in 2.)
