Weitere Überlegungen zur Sveshnikov Variante und Spiele von M. Carlsen bei der WM 2018.
Zuerst habe ich mir in einer Studie ein paar Möglichkeiten überlegt und mit Stockfish getestet:


In der 8. Partie bei der WM 2018 spielte M. Carlsen folgende Partie:
8. Partie: Sizilianische Verteidigung, Pelikan (Lasker/Sveshnikov) variation B33

Zitat aus der Wikipedia:

Sveshnikov Variation: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5

The Sveshnikov Variation was pioneered by Evgeny Sveshnikov and Gennadi Timoshchenko [ru] in the 1970s. Before their efforts, the variation was called the Lasker–Pelikan Variation. Emanuel Lasker played it once in his world championship match against Carl Schlechter, and Jorge Pelikan played it a few times in the 1950s, but Sveshnikov’s treatment of the variation was the key to its revitalization. The move 5…e5 seems anti-positional as it leaves Black with a backwards d-pawn and a weakness on d5. Also, Black would have to accept the doubled f-pawns in the main line of the opening. The opening was popularised when Sveshnikov saw its dynamic potential for Black in the 1970s and 80s. Today, it is extremely popular among grandmasters and amateurs alike. Though some lines still give Black trouble, it has been established as a first-rate defence. The main line after 5…e5 runs as follows:

6. Ndb5

The theoretically critical move, threatening Nd6+. All other moves are considered to allow Black easy equality. 6.Nxc6 is usually met by 6…bxc6, when Black’s extra pawn in the centre gives good play; alternatively, even 6…dxc6 7.Qxd8+ Kxd8 is sufficient for equality.[34] 6.Nb3 and 6.Nf3 can be well met by 6…Bb4, threatening to win White’s pawn on e4.[35] 6.Nf5 allows 6…d5! 7.exd5 Bxf5 8.dxc6 bxc6 9.Qf3 Qd7.[36] 6.Nde2 can be met by either 6…Bc5 or 6…Bb4.[37]

6…d6

Black does not allow 7.Nd6+ Bxd6 8.Qxd6, when White’s pair of bishops give them the advantage.

7. Bg5

White gets ready to eliminate the knight on f6, further weakening Black’s control over the d5-square. A less common alternative is 7.Nd5 Nxd5 8.exd5 Nb8 (or 8…Ne7), when White will try to exploit the queenside pawn majority, while Black will seek counterplay on the kingside.

7…a6

Black forces White’s knight back to a3.

8. Na3

The immediate 8.Bxf6 forces 8…gxf6, when after 9.Na3, Black can transpose into the main line with 9…b5 or deviate with 9…f5!?

8…b5!

8…b5 was Sveshnikov’s innovation, controlling c4 and threatening …b4 forking White’s knights. Previously, Black played 8…Be6 (the Bird Variation), which allowed the a3-knight to return to life with 9.Nc4. The entire variation up to 8…b5 is referred to as the Chelyabinsk Variation. It can also be reached from the alternate move order 1.e4 c5 2.Nf3 e6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Ndb5 d6 7.Bf4 e5 8.Bg5 a6 9.Na3 b5, which is one move longer. (That alternative move order gives White other alternatives, including 6.Nxc6 bxc6 7.e5 Nd5 8.Ne4, intending c4, and the gambit 6.Be2 Bb4 7.0-0!?, allowing …Bxc3 8.bxc3 Nxe4.) The move numbers in the following discussion are based on the move order given in bold.

Ein wenig peinlich, aber lustig finde ich meinen Irrtum, denn ich habe im Bild zur Pelikan Eröffnung einen Pelikan im Muster gesucht. 😉 Inzwischen kenne ich aber Jiří Pelikán.

 

 

Nun hat mich natürlich interessiert, was Stockfish zu dem Spiel meint und die Analyse ergab:


Ich komme mir dabei frevelhaft übermütig vor wenn ich das sage, aber Stockfish meint, dass Caruna einen Fehler machte und Carlsen 3 Ungenauigkeiten unterliefen. Meine Meinung dazu: ein geniales Spiel, dass ich auswendig lernen werde, trotzdem sehe ich mir an, was bei 24. Qh5 passieren hätte können.
