"Contemptible buffoon on the board"
::End Quote - So is the knight in Xavier Tartakower's expression. He spins and weaves laces. For him, there's no calm rest, no little pier. Nevertheless, sometimes, among all ruses, among chaotic, on the first glance, knight-move chains create such amazing positions, that marvelously come easy to you. For example this one.
An ideal position, a ray of high logic. It was extracted from micro studies, composed 102 years ago by Aleksej Aleksandrowicz Trojckij.
The introduction is clear:1.d6+ Kd7
Tentative 1...Kxb7 2.dxe7 Nd7 is rejected by the placid 3.Kg7;
Swobodin's note: Fritz suggests 1...Kc6 that leads to the draw.
2.Nac5+ Ke8
Now, the zest: 3.d7+! Nxd7 4.Nd6+ Kd8 [Picturesque final in variation 4...Kf8 5.Ne6#] 5.Ne6#
The earliest raising of such knight-square-effect construction is related to about 1283, and the discovery in manuscripts is conserved at Istanbul’s library
Irreproachable answer to the purpose
1.Rh7+ Kg8 2.Nf6+ Kf8 3.e7+ Nxe7 4.Rf7+ Nxf7 5.Ne6# That's getting exactitude.
Are such refined brainwave possible only in "artificial chess", so in compositions? No!
Klementz - Eisenschmidt [C51]
1862
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Bc5 6.d4 exd4 7.cxd4 Bb6 Not the best; simply was necessary 7...Bb4+[/png] but in the XIX th century, they didn't know all.
[pgn]8.0–0 d6 9.Nc3 Bd7
[I'd rather play 9...Na5 10.e5 dxe5 11.Re1 Nge7 12.Ng5 Be6
Of course, after 12...0–0 13.Qh5 wins]
Swobodin's note: I'm not sure because of 13...Bf5 14.Bxf7+ Kh8 15.d5 Bxf2+ 16.Kxf2 Bg6 17.Qh4 Nxd5 18.Kg3 Rxf7 19.Qxh7+ Bxh7 20.Nxf7+ Kg8 21.Nxd8 Rxd8 22.Nxd5 Rxd5 with a black advantage.
13.Bxe6 fxe6 14.Nxe6 Qd6 15.Nxg7+ Kf8 16.Qg4 Bxd4 [Last chance was 16...Qg6 ] 17.Ne4 Qb4?? 18.Ne6+ Ke8 19.Nf6+ Kf7 20.Ng5+ Kf8
Taking the knight is losing the king: 20...Kxf6 21.Qe6+ Kg7 22.Qf7+ Kh6 23.Ne4+
21.Ba3! Qxa3 22.Qe6 Nd8 23.Qf7+!! Nxf7 24.Ne6#
See, "wonderful: all is so clean and so beautiful" (A. S. Pushkin) Quote::
что за диво: всё так чисто и красиво (А. С. Пушкин )

Essen - Durf [C22]
California, 1945
1.e4 e5 2.d4 exd4 3.Qxd4 Nc6 4.Qe3 b6 5.Nc3 Bc5 6.Qg3 g6 [6...Kf8 is better] 7.Nd5 d6 8.Bg5 [8.Qc3 f6 9.Bb5 Bd7 10.Bxc6 Bxc6 11.b4] 8...f6
Disproving other defenses is a funny entertainment 8...Nge7 9.Nf6+ Kf8 10.Bh6#; 8...Qd7 9.Bf6!; 8...Nce7 9.Nxe7 Nxe7 10.Qc3
9.Qc3 Ne5 10.b4 fxg5 11.bxc5 bxc5 12.Nf3 Nf7 13.Nxg5! Ngh6 14.Bb5+ Bd7 15.Ne6! Qc8 16.Qf6 Ng8
Attention: now it will happen!
17.Qe7+ Nxe7 18.Nf6#
Mister Essen can hang this position in a little frame on the wall: it's perhaps his best creation in chess.
Zajcev - Storozhenko [C44]
Moscow, 1967
1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.c3 dxc3 5.Bc4 cxb2 6.Bxb2 Bb4+ 7.Nc3 Nge7 8.Ng5 Ne5 9.Qh5!
An opening with complex construction that prepares a luxurious final position. 9...g6 10.Qh6 Nxc4 11.Qg7 Rf8 12.Nxh7 Nc6 13.Nf6+ Ke7 14.0–0–0 Ba3??
Knight c3 had to be immediately eliminated since "he" is the principal attack generator.
15.Ncd5+ Ke6 For a full success, it's necessary to introduce the queen into the attack. 16.Nf4+ Ke7 17.Nxg6+ Ke6 18.Nf4+ Ke7 19.N4d5+ Ke6 20.Qg4+
I, for example, liked too much this
20...Kd6 21.Bxa3+ Nxa3 22.e5+! Kc5
In case 22...Nxe5 23.Qb4+ taking the knight is enough for a winning position. It's possible however to seek something more interesting
23.Ne4+ Kb5 24.Nec3+ Ka6 [24...Kc5 25.Qe2] 25.Qa4+ Na5 26.Qb5+!! Nxb5 27.Nb4+ Kb6 28.Na4#
A nice episode from GM Igor Zajcev practice.
Kuinzhdi - Juneev [C20]
Tbilissi, 1980
1.e4 e5 2.Ne2 Nf6 3.f4 Nxe4 4.d3 Nc5 5.fxe5 d6 6.d4 Ne4 7.Qd3
Dubious venture. However, to refute it, blacks must play very emancipatly and energetically.
7...Bf5 8.Nbc3 d5 9.Qb5+ Nc6 10.Nxd5? Qd7 11.Ne3 0–0–0 12.c3 a6 13.Qa4 Kb8 14.g3
Thank you for collaboration, Maestro Kundzhi.
14...Nxe5! 15.Qxd7 Nf3+ 16.Kd1 Nf2#
Picture has slightly little curves, but it's also very very beautiful.
Loyd,I - Loyd,S
Philadelphia, 1855
1...Nf3+ 2.Kf1 [2.gxf3 Bxf3] 2...Qxf2+!! 3.Nxf2 Ng3#
Vestreninen - Razuvaev
Vilnius, 1969
Here's the grandmaster's duet:
1...Nf1+ 2.Kg1 Nxh3+ 3.Kh1 Qg1+ 4.Nxg1 Nf2#
Tot - Astalosh
Ljubljana, 1938
We conclude the selection with a pair of moves done by the Grandmaster Lajish Astalosh against the famous Viennese Laslo Tot:
1...Qxh3+!! 2.Nxh3 Nf3#
drawing a key. This key, of course, is made by the most unpredicted figure in checked chess ground. UP
