    This one I played on ICC - a 3 minute game with 1s increment. I had the white pieces.



    White has to castle, and I have to avoid a PGN with black to move, so we'll have white in the midst of castling, finishing off by Rf1.



    Now time for Black to castle, 0-0. We'll just make that move for him and come up with white to make move 13.

    Hi SG

    Cannot Black mate in one here.



    Black played Qxe4 but Ne2 Mate looks good.

    Yes - we both missed it.

    He got excited by the hanging pawn; I was hoping he'd take it.

    I've been playing such godawful chess lately, haha.

    Ah Good.

    I thought for a moment with all the diagrams I had messed up the move order.

    You are into retro problems so I suspect the next genre is to play proof games
    where you have to prove the original position was from a Fischer Random
    game and you then have to show the original start position.

    Or are there already already Fischer Chess retro's out there?

    (have a feeling I'm going to regret asking this).

    Heinzkat actually brought this up in the problemist club forums.

    Thread 125073 (not sure if the link will work from here, but give it a go...)

    My own feeling is that it would be tough to make C960 retros interesting. Perhaps if you could do some with fewer pieces on the board, and yet force it to come from a unique starting position, it would be worth publishing...

    Ah that's what was tugging at me. The old Heinzkat post.

    I was also thinking that some of the classic problems could be
    re-invented using the 960 set ups.

    For instance Loyd's famous stalemate in 10 moves.

    Now has to found (and possibly beaten) on all the 960 positions.
    Why not claim one.

    And this famous one from the normal set up.



    Place the Black King on the board with White to play and mate in 3.

    Can now be set in some other 960 positions. (not all mate in 3 with one solution).

    Position setup 150. (I'm claiming this one - you find your own)



    Place the Black King on the board with White to play and mate in 3.

    For anybody who has never seen this.
    Here is Loyd's stalemate from the originall postion in 10 moves.

    Here's one sol for your position 150.

    Arghhhh....... "Here's one sol for your position 150."

    That's my answer.

    Your post hints there are others......have I missed another (others)?

    You said that not all would be mate in 3 with one solution.

    I was not sure if that applied to position 150
  11. 30 Jun '10 00:44
    Ah good.

    I'm 99% sure only 1 mate in 3 from 150.

    I set up the postion on Fritz and moved the King along the 4th rank
    and gave it 30 seconds. (these computers have some uses).
    If there is a mate in 3 on the 5th+ ranks I'm sunk.

    I pulled 150 it at random 120, 130, 140 have no mates or multi mates.

    Your up on problem rights and wrongs.

    I know composers use computers to check their compositions but here
    I did not really compose did I (or did I?).

    I never worked out a solution for the computer to check.
    I gave the computer a random position to see if there was a mate in 3.

    So can I put my name to this or technically is it Fritz's.

    Should I get banned because I'm posting problems created by a computer.
    (is there anything in TOS about it?)

    The consensus is that there's really nothing wrong with using a computer to help create problems. Computers can't usually make a problem more interesting.

    Problems at their best are an art form, like painting. A computer is like a high quality brush. It's a good tool to have, but it can't compensate for lack of artistic talent.

    Problems created entirely by computers are usually extremely boring, like endgame tablebases [think two Knights winning against a black pawn in 102 moves ... ]

    Using computer in solving tourneys, on the other hand, is another matter.

    Cheers SG.

    That last bit about computers. Is this for solving tournaments
    that are on the net? Surely you cannot go to a proper solving
    tournament with a computer. No that's crazy.

    I suppose to beat computers one has to compose irregular
    problems so they cannot take part. Something like this.

    White to play and mate in 14 moves.



    Only trouble is you are not allowed to move either Rook
    and you must give mate with one of the Rooks.

    It was set by by W.Bone in 1906.

    He must have forseen the advent of computers way back then
    so composed a problem to nobble them. A visionary.
