The initial position is legal with white to move.

The move:

NN. O-O

is not legal!

The white Rook has moved before!

The proof:

It is a simple and straight "domino" retro-problem.

Black made his moves only with his knight(s)!

As knight changes its field color at every move. black (and white too) have made an EVEN number of moves before, so "NN" must be an ODD number!

The white - to move - had to gain (or lose) a tempo, since his knight made an ODD number of moves (being on f3 - white field - initially on black). The white King could not gain/lose a tempo ("domino" color change), so the only piece possible to break this "symmetry" is the white Rook. The shortest proof game (one of them):

1.Nf3 Nf6 2.Ng1 Ne4 3.Nf3 Ng3 4.Ng1 Nxf1 5.Nf3 Ng3 6.Rf1 Nf5 7.Rg1 Nh6 8.Rh1 Ng8

and

9. O-O is not legal

Sorry for my bad English

White already guards the black squares in the Black king's field. Bd5 would be mate if White can guard c8 -- Black threatens 1...Kb7 2...Kxc8. A queen-move to the eighth rank would do, but Black also threatens Nxg8, so White's queen must also be ready to mate on the white diagonal if need be. Thus not 1 Qf8? because a pawn obstructs Qf8-f3, but

1 Qh8 Kb7 2 Bd5#

1...N~ 2 Qh1#

Babson #2-

White's bishops, knight and rook on c2 guard the Black king's field. So Black cannot move his king, or his pawn, and must thus move a rook. A White check by the queen or White's other rook would be mate, if Black were to either unguard a square from which White can mate, or block a square.

For a mating-move, Qe2 looks plausible, but Black has Rea3, line-pinning White's queen to the a-file. If White's key moves his king to the b-file, then 1...Rb3+ instead. So 1 a4!, preemptively unpinning the queen.

1 a4 Ra2/Raa3/Rxa4/Rb1 2 R(x)b1#

1...Rd3/Re1/Re4/Rxe5 2 Q(x)d3#

1...Rea3/Rb3/Rc3/Re2/Rf3/Rg3/Rh3 2 Q(x)e2#

1...Rc1 2 Rd2#

Galitsky #2-

White's queen, rook, bishop and king guard the Black king's field. So a knight-move would be mate if Black does not destroy White's mating net. But Ne5 obstructs the queen's guard of g3, and Nd2 works only if Black's knight has moved, unguarding d2.

If 1...Bxe4, the queen must guard f4 as well as g3, and thus can't move to mate. Bxe4 also interferes with the White bishop's control of e4 and f3. Fortunately, Nd2 guards those two squares, so White's bishop needn't, and may thus move. This suggests

1 B somewhere

1...b=N~ 2 N(x)d2#

1...Bxe4 2 B mates

The pawn on g4 obstructs 1 Be8 2 Bxh5, so it's 1 Ba4.

1 Ba4 b=N~ 2 N(x)d2#

1...Bxe4 2 Bd1#

1...B~ 2 Q(x)d3#

1...e=N~ 2 Q(x)f4#

1...Kxe4 2 Bc6#

1...hxg4 2 Re3#

To the Surprise of All

"One of the most surprising mating pictures was encountered in the ancient Eastern problems."

"This final position, found by some unknown chess player about a thousand years ago, is a model of beauty and economy. Many chess problemists have used it in problems and studies, surprising and delighting the chess world. The noted French poet, Alfred de Musset, was no stranger to the beauty of chess. Here is his problem, circa 1845."

#3

"The solution is not complicated: 1 Rd2! Nxd2 2 Nc3 and regardless of what Black plays, 3 Nf3 is mate."

"Alas, that only happens in studies and problems artfully constructed," said one young Moscow grandmaster. "In practice, I have not come across anything similar."

"And so we thought, until we came across this position from Turoverov-Asumanian (1957)."

"Black has an extra pawn on the Kingside, and with Ng3, threatens to advance it. White, therefore, begins forcing play to obtain counter-chances on the other side."

1 c5

"Played hoping for 1...bxc5 2 Na7 Nb8 3 N7b5 or 1...dxc5 2 d6 cxd6 3 Nxd6 Nc7 4 Nc4, with counterplay for White in both cases. White evidently thought his opponent's next move impossible because of the combination which takes a surprising turn."

1...Bxb5 2 cxd6?

"True to himself. The lesser evil was 2 Nxb5."

2...Bxf1! 3 d7.

"The essence of White's concept: he must get a new queen. However, the exceptional nature of the position allows Black to create a mating attack with a minimum of forces."

3...Nc5!

"White resigns. After 4 Kxf1 Nxd7, Black is a piece up, while 4 d8=Q Nd3+ 5 Kxf1 leads to a shortest endgame in practice--5...Ng3#!"

"The elegant combination of the Georgian woman chess player Togonidze in her game with the Hungarian Bilek (1960) led to an almost identical finish, the only difference being that in the last example, the Black King took on the role of a pawn."

1 Rh8+! Bxh8 2 Ne6+ Kg8 3 Nh6#.
