    I enjoy the oddball problems.

    It is the setting and the look on the pre-solvers face
    when you give him the task that gives the most pleasure.

    From this postion after 1.e4 e5.


    White to play and mate in 5 moves.

    White's last move is 6.Ke1 mate.

    See how kind I am to you, not like SG.
    I give you the first two moves to prove no skullduggery with switched boards
    etc etc and 99.99% of you will have had that position after 1.e4 e5 in real games.

    White's last move is 6.Ke1 mate.

    Post but hide the solution.
    If people want to peek and lose the buzz from solving it then it's up to them.

    To 'hide' a comment do this.

    [HIDDEN]text or move here[/HIDDEN]

    But have the word 'hidden' in lower case.

    thus

    1.e4, e5. 2.g3, Ke7. 3.Kd2, Kf6. 4. Nc3, Kg5. 5. d3+, Kg4. 6. Ke1#


    I'm worried though, as there are 2 solutions within that solution, depending on order of moves, and move 4 could be lots of variations... Do I get a SOLV'D?

    I had to be quick with that edit, I missed that last sentence about lower case. Oops

    for 6.Ke1# to work the black king needs to be on the white file for the queen or bishop and for that he has to do some serious Kamikaze work

    What am I missing?

    On the right road morgski - 3rd move illegal.
  7. 23 Feb '11 15:34
    can the king only move forward as a result of being forced to then?

    That makes it a lot harder :-/

    Have to go out for a few hours.

    This was coming in two parts. (an SG trick).

    Once you get dross out of the way I now add:

    The piece delivering the mate is the f1 Bishop.

    So 6.Ke1 mate from the f1 Bishop.

    I have the same solution
    (apart your move 3 that should be Ke2, not d2!)
    and yes there are multiple solutions, but anyway fun to solve and even though easier than SG's problems, still a bit tricky (you can easily go in the wrong direction, as i did)

    It reminds me of the famous game Edward (not emanuel) Lasker - Thomas, which fascinated me so much when i started chess especially because of it's last move (i think it has a big part in my current addiction to this game!)
    It's one of the most famous game in chess history but just in case some of you don't know it yet, here it is, up to the start of the combination which of course you have to find yourself !




    A little hint :
    the game actually finished with a mate with the king (Kd2 mate), although there are other solutions (some 1 move shorter)

    Nice.

    Took me while, with a lot of hopping knights all over the board, but...

    1. e4, e5. 2. Qf3, Ke7. 3. a3, Kd6. 4. Ke2, Kc5. 5. Qe3+, Kc4. 6. Ke1#


    With two variants in that solution with moves 3 and 4 for white interchangeable.

    congratulations, you've improved on lasker's play (if one can say a shorter mate is an improvement)
    in the game white played h4 instead of f4. longer mate but amazing final position (it mustn't be very common that the 2 possible mates in a position are Kd2 or 000!!)

    in your line with f4+, black can last a bit longer with Kh4, then g3+ Kh3 Bf1+ Bg2 Nf2# is pretty too !

    Hi morgski

    That's it.

    There are a loads of these 'Sounds Impossible' mates
    within the first 5 or 6 moves. But they are in there.

    Good to see the most famous 5 minute game in history making
    an appearance.
