Maybe this one was not so bad, White has to sacrfice two pieces for the fastest Mate and Black does a minorpromotion to live a few plies longer, so Rybka would not be able to find the best defence. Mate in 15 moves, computer finds it easy..

Excuse me, but I can not find the checkmate in 15 moves, only in 16 moves starting with 1.- Na4+, bxa4; 2.- b5, cxb5; 3.- Rc3, b4 and then four moves would lead to checkmates in 13 moves: Re3, Rf3, Rg3 and Rh3, none of them featuring a sacrifice of other white piece and a black underpromotion. What am I missing? Can you provide your line, please? Thanks in advance.

Regards from Spain.

Hello Jesús, maybe I spell your name wrong, this is what my spellingcheckker recommended, I think that your solution is the same that Shredder 11 Gambit finds, I know it is not the most recent version of Shredder but I do not have a newer one, and within four hours it did not come further than M16 but I think it is one move too long! My solution actually it was almost solely Crystal's effort, just involves pushing the c pawn to promotion as quickly as it is possible.

I add a little White space for if you want to try again. Output from Crystal is in white characters :P To read you have to highlight the text.

If White plays 6. Kf8 there is no minor promotion anymore, (at least it is not forced for M10, but the minor promotion is equal to 6...Bg7+) Crystal says, several moves for White here with the same number of moves till Mate:

Hello Eelco:

The spelling of my name is correct, though I know it can be difficult for non-Spanish keyboards.

Thank you for the solution! I tried 4.- c6 without success, now I see that the pawn push must be done a move earlier. The start of the solution is nice and elegant. Congratulations! :-) I enjoy a lot all these problems that are posted at the forum with different themes featured: how can be possible that those strange moves work? But they work! :-) People can be so creative!

Regards from Spain.

Here's another Staircase maneuver, it's a mate in 19 this time, ShashChess, Crystal, and Chest of course solves it, I'll include the text to add to your Chest database under the PGN

[pgn][Event "Mate in 19"]
[Site "Columbus, Ohio"]
[Date "2023.06.20"]
[Round "?"]
[White "ShashChessGZ-x86-64-bmi2"]
[Black "?"]
[Result "1-0"]
[Time "06:12:14"]
[WhiteElo "2000"]
[TimeControl "0"]
[SetUp "1"]
[FEN "3K4/1p5p/1p6/8/8/1B6/1p6/b1k3B1 w - - 0 1"]
[Termination "normal"]
[PlyCount "37"]
[WhiteType "program"]
[BlackType "program"]
[/pgn]

Here are the Chest FEN and parameters, just copy and paste the text into your Chest database:

3K4/1p5p/1p6/8/8/1B6/1p6/b1k3B1 w - - bm #19; 00:00+ @
