Not true. There is another possibility.

To be sure we are talking about the same thing: after the black knight moved (once , twice, three times), the white bishop was taken of f6, AND the rook was taken on g3, how can the king still move to the g-file from the f-file?

There is a way...keep looking...it's right in front of you!

I am sure someone will find it. I'm off.

So basically what BigDoggProblem is saying (correct me if I am wrong) is that the White king goes through g4 to h1! Hopefully I will free some time later and try to find possible sequence of Black moves allowing that.

It is clear that the king has to go to h1 via the g-file, and infront of his pawns. But what worries me is his reply on my question "To be sure we are talking about the same thing: after the black knight moved (once , twice, three times), the white bishop was taken of f6, AND the rook was taken on g3, how can the king still move to the g-file from the f-file" . I just don't see that happen! That's why I stopped searching.

If the black N moves once, it is either threatening g4 or it occupies g4 for the rest of the game. Therefore, the wK can't go through g4.

I believe Black's first three moves should be
1.b3 c5 (freeing the d8-a5 diagonal) 2.Bb2 Nc6 3.Bf6 gxf6
The only evidence I can provide is the fact that there is no way to alter the order of the moves which should be fulfilled for such problems.
As for the route of the White king:
I am convinced that the king must travel to h5.A possible route d2 - d3 -e4 -g3 -h4 -h5, so that after White captures at g3 (the Black Knight is at a5 already) the Rook can go via h4 to a4 and a3.
What is problematic in this respect is the next few White moves (fourth and fifth to be precise).

After 1...c5, bRa8 can no longer reach d5 in two moves.

Not via g4, nor via g3 (i.e. before the hxg3 as I formulated it) , as Thud and Blunder replied earlier on. I will be watching with interest what magic path is found.

I spent the entire night trying to find a way, and I couldn't.
I shall summarize my failures for anyone that is willing to continue:
It is clear that White's first three moves are 1.b3 2.Bb2 3.Bf6
What can Black's first three moves be?
1...Nc6 is impossible; 1...a5 2...Nh6 seems to be too slow.
So the only possible options I could see (and thus had to focus on)
1...a5 2...h5 3...gxf6 and 1...Nh(f)6 2...Ng4 3...gxf6
Since what has already been mention the decisive point is the journey of the White king to h1, the only possible route is through g3-h3 (and then h2-g1 so that the Rook may go from h4 to a4 and a3. The only problem here is that I could not find enough spare moves for Black 🙁
For the sequence of Black's moves. The bishop is sacrificed on e3 befor the rook on g3. The Black king's journey is most probably through g7 and takes place with White king's journey (Black may be even castling?!)
a4 is followed by Ra5-Rd5 then c5.
So what I tried was:
1...h5 2...a5 3...gxf6 4.Nf3 Bh6 5.~ Be3 6.dxe Kf8 7.Kd2 Kg7 8.Kd3 Kg6 9.Ke4 Nh6 10.Kf4 Rg8 11.Kg3 Kf5+ 12.Kh3 Rg3+ 13.hxg3 and Black has run out of useful moves.
May it be that the board is reversed?!

Not so! There is another possible route.

Also, this isn't a trick problem. The board is oriented normally, with White at bottom.

Let me get this straight:
1)Castling kingside is impossible due to the bishop at f1.
2)The pawn at f2 blocks the path through f2-g1-h1
Where could the White king move through?
Are we missing something obvious?
