A Puzzle - Find the Double-Exclam(!!)

My latest puzzle creation - White to win Wink








What do you think?... the unthinkable is the double-exclam(!!) Cool

There's lots of solutions but the rest take a lot more moves!!

    Give this puzzle to an average club player and see how many get it right Wink No-one at mine did, you very rarely see under-promotion to a bishop as the winning line, so this underpromotion IS a double-exclam!! Promoting to a queen loses to stalemate, promoting to a rook loses to stalemate, leaving the bishop and the knight. Promoting to a knight wins too, and many studies have 10 or 12 moves that have knight promotions. But glancing at this, it's very hard to see a mate-in-2 - unless you see the moves list Wink

    No offense, but that certainly isn't a double exclam.  It's a clear mate in 2.  Under-promote to a bishop, then N-c6#.

    Thanks! I haven't posted up anymore fully composed puzzles yet but I will get another one up over the summer. I never rush my creations, some weeks I can make 2-3 a day, some months I don't make any at all... I just let the ideas come out when they do lol Cool

    Thanks for the comments guys! Note that in the start position, the black king only has 1 legal move and that is to capture the undefended LSB on b7. Trying to defend the bishop stalemates the king unless promoting to a knight or 1.Nc6+? with the discovery forcing 1...Kxb7 - 1.Nc6+? also wins but takes more moves, the closer you look at the puzzle, you'll see that every piece on the board serves a purpose, taking away every square from the king, the pawn that can be captured is a decoy Wink 

    Solving puzzles like this gives you improved spacial awareness on the board making sure everything is thoroughly checked/looked at before making a move. I'm glad you liked it people! Smile

    That is a clever puzzle, I missed the stalemate point.

    When you think about the squares the king can go and how you can avoid stalemate it becomes easy but at first glance it is hard to see it :) 
    Nice puzzle!
