    This is a challenge to anyone who is interested, to post the weirdest and/or most creative (home made) chess positions you can think of. It's time for the redhotpawn community to escape from the restraints and boundaries of opposition for a while and create some cool chess positions!

    *Odds are not everyone will like every position post, but please consider them to be works of art, and allow everyone to post of their own free will without criticism. On that note, please don't post anything that might be offensive or fraudulent!

    It's legal too. Incidentally, whoever's move it is wins.

    Are you sure? Seems each side just ends up with 3 Bishops at the end.

    No, he's right. Say it's White's turn; he plays Bxh1. The threat of Bd5# is now unstoppable. Black can trade queens, get his queen in position to block, sac his queen for a bishop, try to escape with Kb3, whatever he likes, but mate is certain in a few moves at most. Nifty position.

    1.Bxh1 Qxh7+ 2.Kxh7 and Black's K has two light diagonals to play on. Where's the mate?

    ...Yeah, ignore me, I'm just making a fool of myself as I always seem to do in these puzzle topics.

    I think my first move has to be correct, though. White can't prevent the exchange of queens if Black wants to make it. Since no quantity of bishops is sufficient to mate if they're all dark-squared, he's got to take the h1 bishop if he wants to win.

    However, after 1.Bxh1 Qxh7+ 2.Kxh7, Black gets his piece back by 2...Bxe3. Everything from then on out is an even trade. White can't win.

    You should start by trading queens, then capture the bishop on the white square. It gives you a better position, since your king won't be stopping your white-squared bishop from checking the king.

    Everything from then on out is an even trade.

    Don't go for a trade. Just start moving your king toward the other. By the time your king gets close enough to affect the other, you should still have enough bishops to checkmate him. Then again, I haven't tried every possibility, so you may find a situation in which that's not possible. If so, then just ignore the final comment and appreciate the beauty of the [legal] position.

    How about another perfectly legal position:



    And (another entirely unintended incident), whoever moves mates in two.

    Is the position legal?
    a) diagram
    b) wQh1 instead of wB

    Edit: Prove your answer.

    The position is impossible to attain by normal play. The king is double checked by rook and bishop, but there isn't any way either of the 2 checking pieces could have been moved in a manner such that it blocked the other before the move.

    The same is true even if the piece on h1 is a queen.

    (Just as a matter of record, double check is only possible by means of discovery where the piece moving out of the way also threatens to take the king.)

    Actually I think this position is possible: the last move played was c5xd5+.
