Can you think about an impossible position ?

Sargon, the point was that there are only the 4 pieces on the board. Sure, if you arbitrarily add pieces, it's trivial to solve. Otherwise it's impossible

@Microraver you are right! @Sarg0n is wrong! Your position is impossible because black king is in check and it is white to play. Congratulations! You are victorious!

How about this - try and find a position with no moves period. White to move but white has no moves - I dont mean legal moves I literally mean no moves. I do know a position like this after coming close in a game.

@smagol please show me your position.
I say that all positions where black king is in check (or checkmate) and it's white to move are impossible. Show me an example that proves otherwise!

@hangrad... I don't think the point was 'victory'... just a friendly discussion :)

there are planty of impossible positions, maybe a position with more than 3 pawns in the h file.....

actually i tried in the editor and managed to move 5 pawns to the h file with only legal moves! Can someone move more than 5 pawns to the H file? I'd like to know!

@AnnaTheCommunist You can place 6 pawns on H files. You do it as follows: you sacrifice pieces and pawns to get 5 pawns on H file. You have 3 pawns remaining on wrong files. You promote them all to queens and then sacrifice them all to get the 6th pawn to H file.
It's impossible to have more than 6 pawns on H file because pawns cannot be placed on 1st and 8th ranks.

@hangrad Thank u! But can u have 6 pawns in h file and move other pawn to promotion in h8? So you would have 7 pawns in the H file (before you change the piece to the promoted one)

No. Black has 15 pieces which can be captured, which happens to be the exact number you need to get your g (1x), f (2x), e (3x), d (4x) and c (5x) pawns to the h-file.
That's it. No way to move the b2 pawn to g7(and h8).
