    -White to move, mating in two.
    -There are four possibilities...can you find them all?

    EDIT: on second thought, I was wrong.
    EDIT2 : on third thought, there is no mate in two. Whatever white does one of the bishops is going to be taken by one of the black pawns.

    Wow, that's a ton of Bishops for a fairly simple idea.

    People who come up with stupid problems like this must be either extremely bored or don't spend much time coming up with them...
    (But then on the other hand I'm stupid for posting on this topic. 🙄 😛 🙄)
    Two of these are not solutions. Can you tell why?

    hey...a puzzle is a puzzle is a puzzle...i know it may seem easy to some but those of us who have played for a while do not make up all of the chess gaming population 🙂

    White mates in 2

    This achieves the same idea as your problem without all the useless Bishops, and with tons less pieces on the board, and it's actually sound (there really is only one solution). In general, a composer ought to strive for economy.

    ok...i never said it had to be a perfect puzzle...it was a brainteaser...plus, some more amateur players, for whom the puzzle was designed, would be distracted by all the extra pieces...perhaps your puzzle appeals to the more experienced players (happy medium?) 🙂

    Agreed. I'll grant you four Bishops. 😛

    What would your version look like if the Black King has to be on e4 ?

    It would have more pieces to contain the King's extra flight squares. That is why I moved him to the edge. There's no reason that he has to be on e4.

    Since the topic is bishops, here is my contribution. White to move and win (by P. Heuäcker):

    I think in the original problem the white king is on c1. This makes the solution a little bit longer.

    but it is. there's no reason for it to be on the edge either

    Yes, there is. The convention of economy dictates that needless pieces should not be added.

    Obvious solution. I haven't checked it for a while, but I think ilywrin's profile puzzle has the same sort of theory...
