Interesting positions Once I came up for this, when I couldn't get sleep: I had chessboard near my bed, I started to put pieces randomly on the board and started to make positions, where all pieces were used and none of the pieces threatens any of the opposite piece(s).

I spent many hours then tweaking the position for more strict rules and finally came up for these rules:

1.All pieces must be used

2.None of the pieces are threatening directly any of the oppsite pieces

3.Position must be legally possible (reachable on normal chess rules), so all the pawns must be on their own line, and always in front of opposite pawn, and no pawns on 1st or 8th rank. Both sides must have bishops on white and black squares.

4.At least 4 pieces per side must be on opposite half of the board

5.No piece can move without position being so that any piece threatens opposite piece (that's putting own piece on en prise, or threatens to capture enemy piece)
A piece cannot be placed on the squares of the opposite king movement range, even if the piece is itself supported by another friendly piece.
En passant doesn't occur.

6.Both sides are threatening mate in 1. There may be many checking moves, but only one move must be the mating move.

so finally I had this position on my board:

White:
Pawns a4, b3, c6, d2, e4, f5, g3, h4
Knights e7, f8
Bishops a1, a2
Rooks a3, b2
Queen h1
King g1

Black:
Pawns a5, b6, c7, d3, e5, f6, g7, h5
Knights e1, g4
Bishops a7, e2
Rooks a8, h6
Queen a6
King b8

I have made few other positions too, which are prettier, but they have one flaw, bishop in impossible square (like: black bishop on d8 and black pawns on c7 and e7)

Try yourself making these kind of positions, but be warned, it may take your sanity, since even though you have gotten 31 pieces correctly placed, it may be impossible to place the last piece on the board, and _then_ you must alter the position a little, and then little more, and then finally you may have to adjust most of the pieces again, and it is pain.

Ckytep If it makes you feel any better, I think this sounds like fun. Unfortunately I would have to cut my work hours by half and use my remaining money to hire a nanny and maid if I wanted the time to do it!! Take it easy.

Ok, here is a tip have an empty chessboard, then take randomly a piece and put it on the a1 (if a pawn, then a2) and then keep putting random pieces systemately on the board..

Come on.. I know it can be hard, but at the same time it's interesting, and I really would like to see such positions made by someone...

CKYTEP, (Hi-!) I took the opposite path. To Begin with the original standard Chess set-up and work from there toward the most efficient (least alteration from the original position) path to meet the requirements given. So .....
>>>>>>>>>>>>>>>>
To satisfy #1 thru #4 I just take the original standard starting position to work from, and from there:

..... Move WT b,d,f,& h pawns to WT's 5th Rank. Move BL a,c,e,& g pawns to BL's 5th Rank. But that is all the further I got, because I don't understand your requirement #5 ?
.....
But working from there by skipping #5 and going directly to meet #6 next, from my first position above: Just need to put Kc7 and Kf2. Then Bd6 and Be3. Then move the BL KR to e7. And WT QR to d1. (actually either BL Rook. And either WT Rook or WT QN could be used at this point. But later when I try to meet #5, it needs to be the ones mentioned. So just using the correct ones to start with now.)
So each King is now threatened with P-N6 ++ MATE by whoever is on-move.
But NOTHING is enprise now, before a move is made.
.......
{If #5 is saying it IS OKAy for a piece to be enprise before any moves, as long as it can take the piece that would take it if the other side was on move. Then my position fullfills that since nothing is subject to capture at all before a move is made (?!) ...}

{ Or If it is saying that every piece must be ABLE to PUT ITSELF eniprise with just one move ....then my postion can not do that. If it did mean that, then I need to know also, if that means only pieces which CAN MOVE AT ALL have to be able to move enprise? Or must every Piece be able to move enprise somewhere within one move of it.? .....}

By going from where I left off. Moving the WT QN to c1 & still either Rook can be the one on d1. And then Taking BL Queen & KN and swapping places so that Qg8 and Ngd8. Then the position meet a requirement that every piece (but not every pawn) that can move at all, can place itself in jeopardy of capture with just one move.

So then can you tell me if my adjustment trying for #5 lastly is done right to meet it? Or wrong? Or have I added a new requirement being met there now? [8-) ?!?!?

Was fun getting to there anyways. Better than stacking pieces I think...! ....[&o
Regards, Craig
And on #4, by pieces you mean pawns also? Or just Royal pieces ?
I took it to include pawns also.

Hi ^_^ the rule #5 is that in every legal move a piece can make it MUST put itself en prise and/or threatens oopposite piece OR lets other piece of the same colour to threat opposite colour piece (like discover check)

thus, your position is flawed since there is many places for many pieces to move without putting anything en prise.. but, it is a good start to construct the position :)

Last night I spent 11/2 hours making a new position, it was quite beautiful, but it always had one little flaw, either putting bishop in impossible square (Ba1 and pawn in b2 = impossible) or some piece having a "flight" square, where it may move without putting any piece en prise. It was, however, an interesting operation. I'll try to make a flawless position now and I'll post it here, if I can make it.

rule #4 yes, it means all pieces, including pawns, altough you can make it even tougher to include minor/major pieces only.
