    Mr. Carrobie and Mr. Gambit worked together very well in another article recently to make a very fun read on some complex endgame positions. It seems as though there could be some good work collected together for study. This first problem was a first place winner in La Strategie and is the work of N.D Grigoriev! While it is a pure pawn ending there is more than meets the eye.. White to play and win:
    White: Kh3, e2, h4
    Black: Kd5, h5

    this is really tricky, all i seem to get are drawing positions, if white goes after the h
    pawn the black king can reach the corner and draw, if white tries to promote the
    central pawn, blacks king gets in front of the pawn and gets a drawing position again.
    It is clear that if white is to win, he must somehow make use of these two elements for
    black cannot surely defend against both, the plan should therefore be to advance the e
    pawn, abandon it and at the opportune moment, swing over to prevent the black king
    reaching the drawing square h8. How this can be achieved at present i cannot say.

    The first two moves for white must be Kg3, Kg2, then swing behind the pawn to advance. Run over too quickly to the pawn results in drawing positions like you say..

    Indeed, that was the thinking. Thanks for putting it into a board.

    I did the same with Queens Park in Championship Manager 2001 (no need to make the stadium bigger so saves on channeling investment 😉 - also shows when I was losing time to computer games instead of online chess).

    The Scottish Sun's famous "Super-Caley Go Ballistic Celtic are Atrocious" headline was around the time when I rocked up in Scotland, so they became my surrogate team to follow 🙂

    ****Edit, not that I had anything against Celtic you understand! Ian Wright was playing for them at the time, who is one of my all time legends (that should probably give away which is my non-surrogate team south of the border)

    Well done Mr. Carrobie! You are all over this study! Black does have a slightly scary defense here, but you've got the gist of how white wins. The dissemination takes place: 7. e3 Kf3 8. Kd3 Kg3 9. Ke4 Kg4 10. Ke5 Kxh4 (black can't postpone this) 11. Kf4 Kh3 12. e4 Kg2 13. e5! h4 14. e6 h3 15. e7 h2 16. e8Q (and white will enter a won queen endgame!) 16... h1Q 17. Qe2+ Kg1(Kh3 18. Qg4+) and mates next 18. Kg3 and wins. Masterful work Mr. Carrobie.

    And if black leaves the pawn to promote and goes promotion himself:

    This was harder than it looked 😉
    I suspect white can still force a win from here, but I've run out of free time for today. Anyone else want to take up the challenge? If not I'll have another go tomorrow

    This seems to be white's only way to win... the key move is move number 7 as any other move leads to something that may be a win but may not be. As it is after white's eighth move it seems that white has black in a cage and should be able to mate in some moves.

    Great job tomtom! Good stuff here. This puzzle is a toughie. Play of course continues 9. Qf3+ Kg5(Ke5 10 Qf6) mate in broad daylight! 10 Qg3+ Kf5 11 Qg6+ At last explaining White's fourth move! Now Black loses the queen after 11 ... Kf4 12 Qh6+ else 11 ... Ke5 12 Qf6#.

    My next puzzle proposal is composed by D. Petrov... It is a delightful little devil.
    White to move and win!
    White: Kd4, Rd7, Bg8, Bh4
