I've been trying to solve this one for days (plus I had also tried it some months before) and can't seem to find the answer.
It's from the "stappenmethode" and I have no clue what the answer is to this one. I've tried everything, solving from the diagram, then on the board, then on a screen. I'm pretty sure I'm completely missing the idea, so any idea on how to solve this would be much appreciated.

Note: The theme is king-attack by removing the defender, you are not supposed to try to win material, but, instead, the idea is to mate the king, even if your opponent sacrifices everything - though I generally stop when the material imbalance is exaggerated (queen + something, or around 10 pawns worth).

Any help would be very welcome.

Well I got:

1. Bb2 Qg6

That is as far as I got. A king side mate needs to get one of the rooks over there supported by a battery of Bishops. The Queen may have to be thrown away. I have no idea how to proceed.

f4, threatening f5 or e5? Rd3 to break the pin on the e pawn? Bxf7+?

edit:

1.e5 Qxe5? 2.Bb2 Qe7 3.Bb4

This seems to be cancelled by 1.e5 Bxe5

Black to play and win.

This is quite a nice puzzle.

Just by glancing at the diagram, it's obvious that White's King position is very vulnerable, with big holes in front of him on f3 and g2.

White's other major problem is that he has a rook hanging on a1.

At the moment Black cannot take the rook, because his queen would be trapped (1..Qxa1?? 2.Bb2 Qxa2 3.Qc3! and Black has to give up his queen for a bishop in order to prevent being mated).

So taking the rook doesn't work. But can Black go for a mating attack instead?

Unfortunately 1..Qf3?? fails to 2.e5, using the bishop on d5 to defend along the diagonal. Black would have to then retreat his queen, losing the bishop on d6.

In order to solve the puzzle, Black needs to be bit more subtle.

Hint 1: He should look for a way to either remove or block out White's defender on d5.

Hint 2:
1..Rb5 is one idea, intending to sacrifice the rook for the bishop and then mate with ..Qf3. But Black has an even better move!

I don't want to spoil anyone's fun in trying to solve this, so I'll give the solution in a later post.

I think it's supposed to be Black to move!

Oh?? No wonder it was so hard.

If that is the case, then that makes this puzzle too easy. I'll leave it to orion to solve it. Shouldnt take him much longer

oops, yeah, It's black to move, forgot to mention that detail. Going to look into this a little further. Thanks for the suggestion Tebb, I had looked at both your suggestions, but can't seem to find anything really substantial. Going to look further down those alleys then, thanks.

You've been trying for days? Doesn't the puzzle supply an answer? (Is it a book? )

If an answer isn't supplied, then this is definitely cruel and unusual punishment. (Well, you could always plug it into a box and have it spit out the line, but you'd think they'd give an answer. )

I don't see how it's subtle. ๐ Wouldn't subtle mean something like Rfe8 or Kh8 or something like that?

You can find the solutions online on their site, but I only look them up when I've finished the book/part. If I can't solve them I prefer to wait some time (some weeks) and then try again - most times it works and I find the solution almost imidiatly after the wait.

Anyhow, I've already solved this one now, though I find it weird that this is the only puzzle of the 12 on the same page, that does not end in mate, at least according to my calculations.

OK, then a bit of self-inflicted torture. ๐ I wouldn't have the patience to wait weeks/months to know the answer, but if you get enjoyment from the long thinks, then more power to you.

Yeah, no immediate mate in sight, according to my "box" (to use greenpawn's term), just gain of material. The boxes will give you a quick answer, but the box answers aren't as enjoyable as a good explanation like the one from David Tebb.

Certainly true.

This self inflected torture system does help though, it's practically the only study I have done and it has brought me from 1200 tom 1700 in little over a year on this site. And I didn't solve that many puzzles either. (certainly not 200 a day like wormwood...)

1. ... c6 bxc6 2. Rc8 pinning the bishop, and then, whatever move white makes, taking white's bishop. and then mating with queen and bishop

I believe white plays Bc4 followed by Bf1 in that case.

The only thing I got was
Be5, but the material gained by that seems questionable for a mate puzzle

That is correct though, according to the answer-book.

That had me chuckling.

I've done it as well solving a double edged position and was looking
for White's win when infact it was Black to play and win.

I busted my head over it. In the end I did what I always do if I cannot
solve it. I choose the move what I would do OTB.

Sometimes wrong, sometimes correct. I never give up

Which brings me on nicley to Mr Mad Rook.

You do not give up and look at the soluiton at the back of the book
and you do not plug it into a box for the solution.

I have actually alerted the Mods to this post because it contains
bad chess advice and you really should know better.

(I really have ) ๐
