    It was a while ago (and my opponent never came back), but they were the Captain of awesome (for about four moves on their part).

    Can you get this position in 5 moves.
    Try and work out the fives moves that leads to this position.

    It's actually harder to find than I first thought it would be.

    Fine ... then I'll just change the game.


    Position after white's 16th move. Find the moves.

    Once you figure out that the g8 Knight is actually the original b8 Knight
    then it all fits.

    Staying with the theme of mate in 5 moves here is the last 5 moves
    of a piece of chess magic composed by Kasparyan in 1935.



    OTB mates in 5 in a serious game are rare.
    OTB mates in 5 in a serious game involing players over 2000 are even rarer.

    Though one: I have a solution after Black's 16th move, but not after White's 16th move. The overall idea is there, but hard to puzzle together.

    Finally found it. It's again switching the knights that makes it difficult.

    Very good.

    thanks. Where do you find these kind of puzzles?

    He has 1,00's of the bloody things.

    I saw this one once. N.Hoeg 1935


    The stipulation is to add 10 White Rooks and Black checkmates in one move.

    Setting up the mate in one was fairly easy.


    I can do it with 6 Rooks.

    But the condition is 10 Rooks. So....


    There....how's about that?

    It's wrong.
    The catch is, as with any problem, you must prove the position could have
    happened with legal moves.

    So it's 6 under promotions to Rooks and as Black still has all his pawns
    all the pieces bar the Queen have been fed to the White pawns.
    And if you look at that Black pawn structure you will see at one time it
    must been something like this.


    To let the newly promoted Rooks out.

    The solution is


    Black plays 1...Qxb4 mate.

    All you have to do is show how it happened. I've tried it a few times without success.
    But this to Swiss G is kid's stuff.

    Hoeg's problems are rarely kid's stuff.This proof was quite difficult.

    Ugh. I hate RHP's PGN viewer. I'm always having to debug PGNs that work everywhere else. I'm tired of trying to fix this one, so here it is in plain text.

    Mea culpa - 54...g5 should have been 54...Bg5. Sorry, Russ!

    Although I still wish the PGN viewer would give an another error message besides "invalid PGN inserted - check FEN".

    "Illegal move on move 54" would be more helpful.
