possible or impossible?

i made this puzzle and you have to say if its possible or not

Two DSBs. So, not. What flavor cookie do I get?

Impossible. White's black squared bishop can't have moved from its original location because the pawns blocking it haven't moved, so impossible for white to have 2 black squared bishops with 7 white pawns on the board.

you're right Scottrf

here's another one

#5 Not possible

you're right but do you know why?

Because after 1.Nf3 c6 2.Ng1 it's Black to move (or 1.Nc3 c6 2.Nb1 it's Black's move)

because knights cant lose tempo

Post 5 looks possible. Exemple:

1.Nf3 c6 2.Ng1 Qc7 3.Nf3 Qb6 4.Ng1 Qd8

Unless there's a specific number of moves to reach for the given position, me thinks this position could happen.

The second one is possible:

Ah

here's the answer: impossible

look at the numbers of the rows, the black king is on d1 and because every piece on the board is still there the pawns can't get passed each other

Not possible because of the 4pawns in the corner.

It's still possible:

Alright post 5 with the algebric coordinates inversed White is Black and Black is White... What a bunch of trickery! You got me there (although not a impressive feat:) ).

Okay let's see that's possible but will not occur in the real game. And also there's no bishop sitting on g5.

it's been more than one day but i've got a new one, i didn't make it but i tought it would be funny
