Here's a position with white to move and mate in one.

But before solving, do keep in mind that it was published on 1st April.

Sadly this cannot be a mate in one. Why? The possible checks are as follows: Qa1 met by c3, Qb2 met by c3, Qb6 met by axb6, Ne6 met by fxe6, Nc6 met by bxc6, dxe3 met by Kxe3.
 
I've just listed all the possible checks white has. Since black has a response to every single one of these checks, it is QED (quad erat demonstratum-Latin for it has been demonstrated/proven) that this cannot be a checkmate in one. I agree with post 15...perhaps this was April's fools, so there is no mate in one.

For the first problem there are 9 black pawns on the board....moreover it is mate in two ...may be it is an April Fool prank....

Ya I think so

There are 9 black pawns, which is illegal. Remove any one of them, and white suddenly has a mate in 1. :)

Third problem...promotion to queen or rook is a stalemate....promotion to bishop will give two black squared bishops....so promote to knight..

Avatar of The_Cosmologist

JMB2010 is right, remove any pawn to make it a legal position and it's definitely mate in one.

As for the third problem promoting into a knight just doesn't work.

I made a mistake in this game. Can anybody spot the mistake that I made?

@johnkorean.. You came very close to the answer.

What about white pawn to B6? that solves the threat of checkmate straight away... and then white clearly wins...

How can a white pawn move from b7 to b6?

Another interesting puzzle.

Try this helpmate in six moves. Black moves first, then both sides co-operate until, at the end of a sequence of six black and six white moves, White checkmates on his final turn. A UK grandmaster failed to find the answer despite trying for more than an hour.

How about you?



Avatar of Disgruntled_Sheep

I can do it in 7.... I'm sure it's the right idea, but not quite seeing the sequence
