Ybk 127 for several lines and games.

The article by l'Ami on the Blackburne variation in NiC Yearbook 127 has a diagram exactly like the one in the original post. Maybe that's why the position seemed familiar to me, although that novel arrangement of the knights also sticks in one's memory.

Re that Korchnoi-Karpov game, I recalled annotations by Michael Stean (one of Korchnoi's seconds) in Chess Life at the time. Of 10...Re8 ("R-K1!?") he wrote, "A theoretical novelty based on various tactical tricks. I'm sure it would score very well in blitz games -- but in a world championship match?".

Yes to both. This is D37.

GM Eljanov, Modern-chess:  Before, this line was simply rejected for
many years thanks to the well-known game from the 1978 World Championship Match.
Encyclopedia of the Openings (EO):  In the above mentioned stem game Karpov reacted with 14...e4

14...Bxd3!
Eljanov:  This line is quite young: It was first invented by the German IM Martin Zumsande in 2015.

EO:  This improvement came up a couple of years ago to rehabilitate the entire line.

From the diagramed position (1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 c5 7. dxc5 Bxc5 8. a3 Nc6 9. Qc2 Qa5 10. Rd1 Re8 11. Nd2 e5 12. Bg5 Nd4 13. Qb1 Bf5 14. Bd3 Bxd3 15. Qxd3 Ne4).

Eljanov:  A picturesque position and the most critical one in our repertoire. White has four different options which are analyzed in this and the next three chapters.

Ybk 127 for several lines and games.

ChessPublishing (CP):  Modern engine analysis demonstrates that Black is fine in all variations.

CP:  This all looks confusing if you have not seen it before, but it's
popular at high levels. This game shows that there is still danger
lurking.

I played through Eljanov's analysis and found that he and Stockfish often differred in their evaluation of final positions. Playing on, Stockfish came around to finding equal chances. What's going on? As I recall:  Material was equal. After all the excitement, a few of Black's pieces were left on odd squares. White could not prevent Black from consolidating his position.

Despite the preceding, White still scores well in this line.

Wasn't the second position similar to a Karpov - Korchnoi game?

EDIT: yes, game 21 of the 1978 match.

White "Viktor Korchnoi"
Black "Anatoly Karpov"

Looks like the other position is from the Blackburne Variation of the QGD (ECO code D37) after 15...Ne4.  It's occurred over two dozen times, including in Caruana-Nakamura, Croatia GCT Zagreb 2019. Apparently Black is keen to show the importance of centralizing one's pieces, especially the knights.  Wink

Spanish Game: Closed Variations. Smyslov-Breyer-Zaitsev Hybrid (C93)


Yes. It is definitely in the C92/3 complex. I reached it from the Zaitsev (C92) move order, as in the game you posted.

Thanks for the recent game.

I found these positions to be so striking that I wanted to share them. Then I had second thoughts that this might not be relevant to the website. I was thinking of pulling the post, but too late now.

These positions are critical to their respective openings. In both cases the play is very complex from this point onward.
