[BobG]

Provided the image works (hope, hope) what was Black's last move?
(it's currently white's turn)

This is a pretty easy one. For some harder ones, check:

I am awfully sorry, but could anyone please explain me, why do i get:

I got the same message. It's confusing, but perhaps the picture is awaiting authorization by the admins ?

I love these chess puzzles; Raymond Smullyan's "Mysteries of Sherlock Holmes" and "Arabian knights" are great.

haven't seen those two by Smullyan
I remember enjoying very much a book of logic puzzles by him
called
"What is the name of this book?"


an exellent sample question from that book was:

"which is better, eternal happiness or a ham sandwich?"

 

[vikasj007]

i saw the picture, but it was a bit bizzare. i mean, i could see just the black peices, the white ones were nowhere around.

please check the page.

When I click on it, it comes up fine, but that might not necessarily be a good test, since I'm the one that posted it.

Should have had only one black piece: Black King at A8.

White pieces: King at C8, Bishop at G1, Pawn at H2

(A-H left to right) (1 - 8 bottom to top)

Here's an interesting idea for the last two moves

black, K a7-a8
white p g2-g1 ->bishop

It is rare to ask for a bishop when advancing a pawn, and also rare to use notation which starts with black in the 1 and 2 ranks, but it is not unheard of.

Maybe white was toying with black...who anyways is doomed in 4 or 5 moves.

Well, I admit it is creative, and you at least noticed the problem with the bishop's location, but that's not what happened. In other words, the problem uses normal notation with white starting from the 1 and 2 ranks.

Oh, I discovered the real solution right away. I'm just horsing around.

[Ursole]

1. Nb6-a8+ Kxa8

=======================

WHITE:
King on c1
Rook on b1
Knight on a1
Pawns on b2, c2, and d2

BLACK: King on a2

What was the last move played?

 

[BobG]

Ursole was correct.

Last two moves on Ursole's puzzle:

Black - Ne2-c1 (any pieces taken unknown)
White - Kd1xN

 

[Ursole]

Well done, BobG.

A normal game of chess begins with 1. e4 and ends with one player playing NxR mate as his 5th move.

Reconstruct the game.
