Hmm, how do you insert a diagram?
After 1...Nh3, a better defense is

2.Rxh3+ Rxh3+ 3.Kg1 Rh8 4.Kf1 Rh1#

extending to four moves.

Now it does have 8 ranks and still 🙁 Well...
Finally, hehehe, I feel smart 😉 Okay, so White to playa and mate in 3.
Ah, that is a neat one. I was not able to solve it, so I won't be posting the answer.

The king has no choice but to take that rook... I just couldn't find this line! I kept looking at Ke6... keeping black's king locked in...

I never expected this line.

Yes. This was a problem published in 1859 by the famous composer F.Healey, founder of the Bristol theme.
Anyway, try this one /mine if a bit plagiarized/:



Edited: Ah, yes I forgot White to play and mate in 3.

Please PM me the first move... I've got a feeling this is mate in 4 at best?!

Thanx for the PM... that still hurts my brain! One of the combos is very tricky, and I didn't even realize... never mind... that is a great one!

Shouldn't all puzzlez be "white" to move?
This could be an convention that mekes puzzles easier to understand.
If a famous (GM) game ends up with a puzzle this (my) does not count anymore.
hm?

Isn't that one a bit flawed? Cos with 'good' black play, he can make it a mate in 5.

I don't think so. A white King and Rook in such positions should give a big hint:

1.Bf3! Qxf3 2.Qb7!! Qxb7 3.0-0-0#.

If Black declines to capture either piece, he is mated more mundanely.

Most forced mate compositions are with white to move by convention. However, I don't see the problem if someone explicitly says "Black to mate in 3". And there are some good retrograde analysis problems that force the solver to deduce whose move it is.

BigDoggProblem you seem to be rather good at solving such problems. Okay here goes a beautiful one (againa mate in 3) by my personal favorite puzzle maker Samuel Loyd. Here it goes:

White to move and mate in 3
The real challenge of this problem was not to look at the Sam Loyd book in my library! Fortunately, it wasn't too hard to solve once I considered the key.

1.Qh8!! and now four variations.

1...Kxe3 2.Qd4#
1...Kg3 2.Qh4+! Kxh4 3.Nxf5#
1...Kg1 2.Nd1! Kf1 3.Qh1#
1...Ke1 2.Nd1! Ke2 3.Qc3#

I counter your puzzle with another puzzle (author withheld to make things more interesting...)

A game ends with 6.BxRc4# (White's 6th move). How did the game go?

That last one would be Kd2... not e2.

Yet another neat little puzzle!
