White to mate in one


(btw, Problem 1,3,4,5 and 6 have been composed by Polgar)
(Problem2 contains extra hint now in ROT13)
(Problem2 contains additional hint posted 13 nov 2003 18:00)

There are a couple more curious mates in one, which I'll post one at a time.
I will edit this post to contain the new problem, and repost the old one under this topic, giving just one overseeable thread.

My answer is obscured using Rot13 so I don't give it away for others who want to try:

Do either of the second two involve distracting your opponent while you add pieces to the board?

lol, no greg, it's a matter of deduction:

1. With whites next move, black is mated (clue provided by me)
2. Normal chess rules apply (clue provided by me)
3. Elementary my dear Watson (clue provided by Holmes) :twisted:

An extra hint has been added with problem2 in ROT13 format as it actualy gives it all away with that aha feeling.
Believe me, it's on the tip of your tongue, almost.
One move away from that good feeling of mating.

This was the last of them Greg.

Isn't there a maximum of replies shown per page?
I noticed that the tournament2003 post in the General forum contains 38 reactions, without pagebreaks, though the General forum index has been spread over two pages.

It impossoble for black to have moved last,
so white must have made the last move and black is to move now.
But whatever move black makes, white mates in 1.
Observation is the key to the solution :wink:

Nothing wrong there.

It's a mate in one for white, but you need some positional insight to find the mate in one.

Good luck

mmmm why?????

Post by bparsons » Tue Nov 25, 2003 9:59 pm

Why is everyone using secret code to post their responses. That makes it very hard to have any kind of discussion about these positions or moves.

Just come right out with it and leave the secret code behind....

A lot of people normally make in mental overview of a page. What fun would it be if you see a puzzle and directly below the answer.

It's like seeing the football (soccer) results in a newspaper headline, while you still have to see the taped game.

Now a simple quick scan only makes you see garbled letters so you still can enjoy the puzzle in its fullest.

That's true. However, for the purposes of discussing the possible variations it makes it harder to have to jump off site, decode the garbled letters, and then come back to make your reply.

Why put a coded response at all if the intention is to keep the solution secret?

Concerning problem 2. I don´t know was that simply mean, but it was certainly simply stupid. Ok, you can say that the solution was within chess rules, but it clearly was NOT within problem chess rules. You see, if there is a problem that says "White to mate in one" (or in however many moves), it is always, ALWAYS, white to move. So the right answer to that problem is: No solution, impossible. Thanks for those other problems anyway, always bit difficult to see those underpromotions and especially tricky those en passant -solutions, it just doesn´t come to your mind that easy... :D

Thank you for all those puzzles, tellymetwise.
I finally found solutions for all of them, except problem2.
But it is hard to start thinking another way and about other things on the board than just moving pieces.

By the way, is there always white's turn in all problems? :wink:

puzzles with both white or black to move exist.

And only a tiny fraction of those exist where both white and black can win if it's their move.
