Schack matt / Check mate
Can you do a check mate in four moves ?
To be able to find the position of this cache you will have to learn how to do exactly that.
Do not use the coordinates above, they have nothing to do with the actual cache location.
You are playing the WHITE pieces. Describe, using algebraic notation *, WHITE's four moves with which you can place your opponent checkmate. We assume that BLACK is not aware of the danger and does nothing to facilitate for you, nor does he do anything to stop you. BLACK is simply ignorant about what is going to happen.
Use THIS LINK to test your solution. There are several variations of the solution. If you submit one that is approved, you will get the coordinates of the cache in return for your effort. Try different solutions and you might get a small surprise.
The cache is a black 35 mm film canister with a loggbook and a pencil.
Good Luck !
