Promoted from the only missing pawn, the black one?

That was back when promotion rules weren't that strict. ;)

@Caliphigia, 3 years later, white has 8 pawns but only has two bishops. This wouldn't be the reason for an illegal position, being that black does have 3 bishops, but only 7 pawns. PS, good calculations.

Dude, two white bishops are on the same colored squares.

Dude, one of them is promoted. :P

Then why does white have 8 pawns? White can't have two bishops on the same colored squares and 8 pawns at the same time. This is an illegal position.

Why does the white king have to move all the way to e3 instead of just jumping between a3 and b3?

If he just wanted it to be longer, why not put more pawns on the h-file? 

Remellion

a6 is covered by the knight.

The king is needed on d3 to threaten the e3-pawn so black can't move his bishop to d4-f6-h8 to mirror white's tempo-losing rook moves.

b5 is covered by the pawn on c6. In any case, the king is needed on d3 for the reason I mentioned.

Also, if you look at the "safe squares" for white's king, there is a long one-square-wide corridor he can step through, namely b6-a5-a4-a3-a2-b1-c2-d3(-e4), none of which give him the chance to triangulate to lose a step, so he must park himself on d3 while his loyal rook does the job.

Yes, you could promote to an opponent's piece, but black had two bishops on the same colour squares as well.

extra long triangulation like a gajillion times??

Remellion

How about 5. Rxd2!+ exd2 6. e4 d1=B!! 7. e5#! (White is not confused by black's epic promotion.) Yes I have a sense of humour, deal with it.

BigDoggProblem

That's what happens when you promote the Siamese pawn.
