in how many moves can you reach the following position???

OR you can say that its impossible

Impossible due to the rook never leaving the 2nd row... therefore the black king could never get to the A1 without make an illegal move! so Impossible! now if the pawn was on d4 then it would be possible

are you sure???

the king also couldn't move through the white pawns, and if they never moved (if they had they could never return to this setup) that would be necessary.

Another impossible.

Now if the black king was actually on a8 (on the rank where it starts), then maybe it would have been possible.

I think it's possible. The black King may be on e1, white rook on a1 and knight

on d1. Then black King passes via d2 by several moves.

I don't know how many moves it takes.

But what about the entry point on h3-g2? If all of White's pieces move away from these squares, the Black king may be able to go through the pawns here get all the way to the back rank and the a1 square. The only tough part is getting the Rooks out of the way proper. I'm working on this.

EDIT: Black's king cannot get into d2. The pawns on f2/b2 cover both entry points and cannot be moved to achieve this position.

hmmm...hard to get the rooks out of the way....,you could always retreat a N!

It must be impossible. There is no way to get both rooks out of the way of the king's path. Shame, really, as it would be a nice position to reach.

I've tried some knight play to cover the Rooks, but it seems really hard to do this right without stalemating Black (as in, he's forced to take one of the pawns because it's his only legal move).

Nytik, as far as I see, all that needs to happen is that the Rooks are constantly covered by Knights. Let's say the Rooks start on h1 and a1 with Knights on b1 and e5 (to prevent it from blocking/guarding the h3-entry point). Black then enters via h3-g2; the Ne5 moves to g1 to cover the Rook. He proceeds to d2 and the a1-Rook must transfer to somewhere on the Kingside where it is covered by a Knight, to allow entry on the Queenside. Unfortunately this seems near-impossible to do without forcing Black to move, and his only move with a Rook on the back rank is to take a pawn. It seems like it's still doable, though...

HINT:it is possible

now the only question is,how???

Silly.

unfortunatly,no

i'll start workin on this

Impossible

The puzzle says "White to move".

That means the last move was black's, and must have been a king move

There is nowhere the black king could have moved from, as it is completely surrounded

Therefore impossible.

Its possible: Black king goes to g2 by passing h3; set then the one's white rock on h1 and the knight on g1 (the other rock remains on a1 / knight on b1), the black king goes then to e1 so white can play knight on c3 with check, king goes on d2, rock to e1, knight to d1 and the black king can go to a1. Then all figures go on their place, last move is: a black knight jumps on f1 and the white bishop takes him. Moves ca. 45.

sorry,fixed it

It is actually rather simple. Follow these steps:

Evacuate all of whites pieces except the rooks and knights after the pawn moves. Slowly bring up the black king while allowing the rest of the black pieces to die except the queen.

Move the king's knight to f3 when the black king is on f4. Then move Kh3 Ng1+ Kg2 and march the king down while making pointless moves with the other white pieces.  Finally go to Ke1 Na3+ (the rook) Kd2 Re1. Bring the knight to d1 while making pointless moves with the black queen. Move the King to a1 and bring the bishop back to c1.

Bring the rook to d1 after removing the knight. March the white king to f1 and queen to e1 and realign them into their final spots.

Bring the pieces all back home except the white's queen's knight and white's white squared bishop which should be put on b5 and h3 respectively.

Depending on the number of moves you have made, the black king should be on either a1 or b1:

If on a1, Bf1 Kb1 Nc3+ Ka1 Nb1.

If on b1, Bg2! Ka1 and the pattern above.

This is nice and all but obviously takes no real chess skill and forces each side to cooperate. The actual number of moves varies. I could probably figure out the minimum but I do want to spend my life doing other things. I'm going to assume you've read it somewhere, Lycan148, so kindly telling us would be nice.

Scarjo - Nice work.  52 moves looks pretty efficient. 

Lycan - Thanks for the interesting puzzle.

hmmm....yes i am going to kindly tell you

here is the miminum moves,32

oh...and,i got it off chessville
