My story involved a horse taking a lady to a cathedral where she then climbed the tower.

Helpmate in 3
Here is another one



Black to move, helpmate in 3 and there are two solutions.

My story...
... is less ... erm ... romantic.
Cavalier Roland to a tower came, where an ecclesiastical personage related where the lady might be found.

Helpmates in 3 might be a wee beyond my powers...

Helpmate in 3 - March 14.
I have tried to solve this helpmate in 3, for more time of a hour, I have not succeeded. It seems very difficult.
I will try again.

Hints for helpmate in 3
a) Both solutions have checkmate with a double-check.
b) Both involve an Umnov theme, which is (according to the article where I found this) where a piece occupies the square which another piece just vacated.

This is a difficult one though. Let me know if you'd like the solutions.

Helpmate = marriage
Helpmate is similar to a marriage. That is, after marriage, a couple cooperates each other to raise a big family with many children. In real chess, mating attack is a vicious process to kill the enemy king and end the game. In helpmate, the ending has a desired effect. The opposite is true in real checkmate. Correct me if my interpretation is wrong.

I find a solution with discovered check and not with double check.

Do you want to send me a PM with your solution?

Ace-of-aces has a nice line where white gets checkmated in a helpmate. The two solutions I was looking for are where black gets checkmated after white's third move.

archduke_piccolo has revealed a solution to me; thanks to this, I found the other one. Very difficult problem.

A long time...
... it took me to find just the one solution. Actually I found the idea for it having the position set up wrong!

I had half an idea of the nature of the second solution, but was unable to imagine the arrangement of pieces that would lead to that solution. Not. Even. Close.

Incidentally, that is the approach I take to problems such as these. Try and set up a final position that might be reached in the requisite number of moves. Sort of like retrograde analysis.

@ archduke
Your approach is smart. Keep it up.
The second solution is perfectly homogeneous to the first, for this reason, after reading your personal message, I easily solved the second solution.

Helpmate in two moves, with 3 solutions

black side is below. Black move, of course.

Being the author of this problem, I am unable to say if it is difficult or easy. You will tell me.
But I want to emphasize that difficulty is not the most important property of problems.
This problem in particular has qualities that the judge liked, but certainly among these qualities there is no difficulty. The judge knew the solution immediately: the author must communicate it!

I've found one...
Still looking for the others...

Old solutions
It's time to give the solutions of the first 3 halpmates.


1. ... Nb7 2. axb7 Rc8 3. bxc8=N#
1. ... Ne7 2. fxe7 Rd8 3. exd8=Q#



1. ... Kf6 2. g8=Q Sf7 3. Qxg6#
1. ... Rb6 2. g8=R Re6 3. Rf8#
1. ... Pd6 2. g8=B+ Kf8 3. Bxd6#
1. ... Rb8 2. g8=N Rd8 3. cxd8=S#

four promotions of the Pg7 to Q,R,B,N



1. ... Nd6 2. Rg3 Nd5+ 3. Rc3 Kc6 4. Bb5#
1. ... Kd4 2. Bg8 Bc4 3. Bh7 Kd3 4. Rd6#

Is this problem too difficult?

I managed to solve it and have sent you the solutions.

Nice puzzle. I found the first two solutions fairly quickly (having not read the question properly to begin with) but it look a little while longer to work out the third even though I had worked out the pattern by then.

5imon and archduke have solved the problem correctly. Well done!
Some comments from me later.

Here the solutions
To end the discussion on this problem, I want to explain the reasons for the artistic beauty that led the judge to give it the 5th prize.



Solution: (moves black, white; black, white)
1.Nb4 Ra1 2.Nxf5 Rg1‡
1.Bb4 Rd3 2.Bxf5 Rxd4‡
1.Rb4 Rxa7 2.Rxf5 Rg7‡

The first black move always occurs in the same house, 'b4'. It has the effect of opening a line to the white Rook.
The second black move also occurs in the same house, 'f5', and also putting its own piece under nailing.
Note the correspondence of the black moves: Knight-Knight; Bishop-Bishop; Rook-Rook.
While all white moves are carried out by one piece, the Rook.

The mates occur thanks to the nailing. After finding a solution, it becomes easy and intuitive to find the others. But this is not a defect, but an advantage, because it indicates the great homogeneity of the solutions.

I hope my english is clear enough. Thank you for the attention you have devoted to this work.

Very quiet this club.
I try to arouse interest with a three moves checkmate problem.
