AMAZING puzzle, incredibly difficult.

Nice puzzle, I won't lie I could see it was so close; but did have to think about it for a while to get it.

I have seen this puzzle too, Chessmaster as well. It is a cool puzzle. It is a great example of Zugzwang.
This thread was mentioned by broze in another thread (The hardest puzzle ever composed). It shows what is called "Organ Pipes" theme, and it is not regarded as a difficult problem. An impressive achievement was to combine the organ pipes with mate changes, so that all four thematic mates are changed. Before this, I am posting one of the best combinations of the Organ Pipes:
White to play and mate in two moves

This puzzle is also on Wikipedia.
The composer, Thomas Taverner, wrote a 1924 book about chess problem composition and solving. It's public domain, and you can find it in various places on the internet.

Nice puzzle .
There is an easy way for solving it:
In the position, if suppose it is black's turn - on every black move there is different mate - on every, except ...Bg5 .
Realising this I just looked how to change the position with white's first move ,as to be possible mate after ...Bg5 , too.
it's a bit stupid (as in whites just can't loose no matter what they do). If you did the same thing, but playing black, then it would be amazing. Nice puzzle tho, took a while for me to see that move. At first i was thinking about taking a castle with a horse and then either thank you very much for a free piece or check mate.

There is Re3 too that prevents mate at initial position I think, but i used the same thinking pattern that you

Brilliant. The fact it's a we little mate in two make is that much better. A note white has every piece.
I do not get this puzzle
