Not impossible -- it happened to me once. I offered a draw and he accepted.
the IMPOSSIBLE position
Black can't move into check.
Or the other one, knights and bishops are in the wrong place.
lol didn't see this knight/bishop swap
In the first diagram should white have had a promotion of a bishop to have two bishops on the same color. But white has still eight pawns and in no way can that promoted bishop return behind its pawns.
In the second diagram scottrf is looking it from a black point of view having a good reason why the position is impossible. However, I thought about the situation of undiscovered checks in which two pieces can give check simultaneously. That is not possible if the two pieces are equal to oneanother and completely impossible if the two pieces are two pawns.

No-he's right. It's a known theoretical position since the times of Philidor. It has been played by all of the world champions, with mixed success. Most common move is Qexh5, but some prefer to go with Qgxa4. Personally I prefer the second option.

What position is well,"impossible" that you can think of?
That is SO impossible...
