Bump. No one has solved the "best line" so far  

p.s. I didn't want to give clues earlier IM @pfren, but the line is much more spectacular and forcing a win compared to 1. Be4 only. When the solution is revealed, I think even you will agree that the solution is more satisfying than 1. Be4 (although that move is also "winning" for White I easily admit).

 

Set it another way, then.

White to play and mate in 3 moves -  now it does sound interesting.

White to play and win - useless junk... everything, or almost everything wins easily. Nobody will ever care during a game to find a better move if the most obvious one is winning trivially.

It's funny because the solution of the 11th puzzle is to reach the exact same position of the start without the g4 blacks' pawn to checkmate in two.

Here it is.  When you sent this message, it was night time for me because of time zones lol. Lebanon is 7 hours ahead of me (I am in Eastern Standard Time Zone, U.S.A.). 

Here is the 11th Official Puzzle Solution.

I am a bit surprised at the lack of observation IM @pfren; @magneto616 tried to help, but made an innocent mistake of recreating the wrong pgn. I should hope that you know by now that this is a serious forum thread of mine and I won't post a poor quality puzzle like a mate in 3 and then take a longer route for no reason. By the way, I say "White to move" because I don't want to give clues to the solver. If I say "mate in 10", then they will immediately begin looking at mating nets while not all of my puzzles result in checkmate.

+1 Yes, that is the underlining reason to this long checkmate (that is the shortest forced checkmate [in 10 moves]). Very cool composition.

Oops didn't notice I didn't include the pawn

No worries, I know you meant well by trying to post the solution @magneto616 gave. Just next time, copy the pgn from the original puzzle instead of creating it manually via analysis. Copying from the original puzzle makes 100% sure there are no mistakes  

We have all messed up pgns at some point - as we know in chess, one or two subtle differences can make a world of difference.

Here is the 12th Official Puzzle. Black has just captured a White Knight on f6 with ...exf6, so now it is White to move and win. Disclaimer to this puzzle though: there is at least 2 "mainline" continuations that branch at a certain point that both win for White. Good luck

This puzzle was given to me by kJDG12, from this site. (no usernames or links given, or it may not remain hidden in white text).

I'm calculating e6

Avatar of chamo2074

I see a tricky stalemate line with e6 pawn x g pawn and after white pushes black is one square from promotion and if Qg8 to defend g7=Q QxQ  stalemate

I hope I haven't missed anything.

 

1. e6 h4! (1...hxg4 2.exf7 g3 3.f8B! g2 4.Bxc5 is a trivial win) 2.e7! h3 3.e8B! h2 4.Bc6 Ka1 5.Bh1 Ka2 (5...a2 6.b4 cxb4 7.c5 b3 8.Kxb3 Kb1 9.Be4+ Ka1 10.g5! is an easy win) 6.Be4! Ka1 7.b4 cxb4 8.Kb3 a2 (8...h1Q 9.Bxh1 Kb1 10.Be4+ Ka1 11.c5 a2 12.g5! white wins as main variation) 9.c5 h1Q 10.Bxh1 Kb1 11.Be4+ Ka1 12.g5! fxg5 13.c6 g4 14.c7 g3 15.c8Q g2 16.Qc1#

Your lines are nice Spaceysmile. I don't know if everything is correct until the 16th move in your calculation but it looks right.

13th Official Puzzle; I find this one to be challenging, but it is a good one. Give it some time and see how everyone does  White to move and win.

Nice one. After the first 3, almost obligatory moves from each side, I was ready to give up, until I noticed that Black has no good moves to play.

Hi, I am first time doing these stuff. Rc8+, Kb7, bxb3, then now the black has no way to win and white just do rook checkmate and if have chance the take that bishop.
