...Nf5
Mate in two
Sort:
1. Rb5 Qxa8 2. Re5# is also another possible solution. and if you play 1.Rb4 Nf5 delays the check mate, since the knight defends d4, and if pawn takes knight the king gets a way out delaying the game even further.
If 1.Rb5 and black zugzwang, then the mate does not come in 2 moves as well :/
These are good alternative points. However, most players would impulsively take out the threatening bishop. If Nf5, Bxd5 leaving white with little chance of victory. Still, these problems are not flawless..
There is a solution, but you have not yet found it!

As always, Heinzie is correct. No correct solution yet

It took me about half an hour to find the solution. I must suck at puzzles.
I found the real solution, not the "solution" in the OP. It's a pretty puzzle.
The question that comes to my mind is how did that bishop get onto the a8 square? It seems artificial to say the least .... To have been on that diagonal it would have had to have been checking the king already, then black puts his queen in the way? Maybe the more expereinced among you can tell me how that bishop got to be where it is....

Found loopholes in 1. Rb5.
Now I am in favour of 1. Rc6
Is that OK?
Rc6 ? how ?
zugzwang, sorry if I miss typed (not really sure how to spell it though), my point is if black does a move that changes almost nothing in the game, in the case of Rb5, moves the knight or one of the pawns, there is no mate on the next, therefore black delays it...

That's a very eloquent variation on the checkmate indianteacher. Like it

Not too difficult once you see that it's a Zugzwang type of problem (as someone mentioned above). A sure sign is that the target king is immobile.
After 1.Rc6, any move by Black is bad ! - moving the queen allows White to double-check(mate) the Black king(or pinning the queen & mating).
Any move by the Black knight takes it away from the task of guarding the e6 pawn.
Any pawn move either removes an escape or allows the rook to mate on c4.
Edit: Only just checked the the diagram in post#1 & realise that the solution given in the OP's diagram is wrong !
Black is under no compulsion to take the bishop & instead plays 1...Nf5 to ruin any chance of mate in 2 moves.
Having read the thread properly, I see that rstoledo has already pointed this out !

Not so much a variation as the correct solution !

I agree
In light of indianteacher's solution I also came up with this "variation"

Sorry Ray_Malcolm but that doesn't seem to work either (#18) - again you're assuming the queen captures the bishop. But what if Black plays 1...d3 instead ? I can't find any 2-move mate after that ...
1. Rd6 d3 2. Bxd5+ ( 2. Rxe6+ Nxe6 ) ( 2. cxd3+ Kxd3 ) 2... exd5
With the rook on c6, it can mate at c4 but not when you put it on d6 !
Okay Stephen_33 but what about indianteacher's solution? That isn't necessarily flawless either. What if Rc6 then d3 is also a possible continuation. The black queen is under no immediate pressure to take the rook. From there black could move Rc4, which is also a checkmate I believe, as the queen can not take the rook and there is nowhere for the black king to go.
I personally am finding it interesting to analayze these positions from different angles and question the strengths and weaknesses of a particular given checkmating sequence. I think Stephen_33 is possibly taking chess puzzles too literally and assuming that they relate to the real world of chess games. I see chess puzzles as I kind of artificial environment in which you can hone your checkmating skills. They're not necessarily meant as finite puzzles with only one correct answer. Rather they are for chess players to expand their knowledge of how to checkmate and to evaluate strengths and weaknesses in their moves.
As it stands in this puzzle, black is hopeless, as the king can not move anywhere and checkmate seems to come whatever black tries.
What in the world are you saying, Ray?

I'm a little confused by your last comment Ray_Malcolm. I think if you study indianteacher's solution properly, you'll see that it is flawless & the correct one ! He covers 1...d3 as well as every other defensive move Black can make but there is no defense.
You write that Black could move Rc4 but I think you mean White ? Anyway 2.Rc4 does give mate but indianteacher covers this above.
As for taking chess puzzles too literally (again I'm confused by what you mean), if you follow my postings on the puzzle threads then you'll know that I stress to people that a puzzle is not the same thing as a game, except perhaps when they're derived from a game. In fact there's only one rule that applies & that is the solution must do what it states in the title !
In other words, the solution to a mate in 2 moves must be in no more than 2 moves & there must be no possible defense against it. Nothing else will do & I think most serious puzzle solvers on this site share that view.
