Here's the solution 😉
There are two solutions but only one first move!
1.Rb8!!
If ..Rxb8 then 2.Qh3+ ..Kg1 3.Bd4#
This line works for any black move that takes the rook off the d-file, however, black has another defense...
1..Rf8
One would assume that the previous mate still applies, but it no longer works in three as black c ...[text shortened]... ptures then Rh8#, if he moves the rook then Rf1#
A lovely puzzle, i think you'll all agree.

Don't forget 1...Re8 2.Ne7! or 2.Bd4!
It's interesting to see how badly engines spot zugzwang! The thing that makes this puzzle so hard is the fact that you need to find zugzwang TWICE! Normally composed position like this aren't very useful for chess improvement but this one is an exception in my opinion as the counter intuitive nature of the position offers the solver an inside out perspective that is extremely rare in an actual game situation. I'd love to meet the person who invented it. Apparently it was taken from a street hustler in the far east somewhere. If you could solve it you got a free packet of cigarettes. 😵
EDIT: Actually you're right, after 1..Re8, 2.Ne7!! is essential as 2.Qh3+ ..Kg8 3.Bd4+ fails because of ..Re3. Very nice. 😀

the answer is:
1. Nf3 Rh8
2. Re5
forced mate
or
1. Nf3 Rd7
2. Re5

It eliminates the dual after 1.Rb8 Re8. In the original version, 2.Bd4 and 2.Ne7 both work.

There is great wisdom in my response. You should take it to heart.

Originally posted by BigDoggProblemI totally agree, the extra pieces are there to confuse. I would love to know the number of mates in 4!! They must run into the 30s-50s!!
