I fail to see the connection of this game with the lines discussed in this thread: I was expecting 10. NxBe6. On the other hand on 9. ... NxNd4 10. BxNd4 Be6 11. h4!? and you start the K-side attack without castling - that was the point of this thread.

Still well done, nice game to watch, but irrc $3 = !! (a bit generous for a 9th move, don't you think?) Grin

Thanks. But regarding the 3 !! marks its 1 week of Huge computer aided analysis on a hexacore using several engines + my lines. If you closley look then you will see in the latest books 0-0-0 and Bc4 are main lines. I wanted to go out of book where white has scored 55% in g4  in ICCF and 0-0-0 scoring 71%. 2nd one is for the score as after that that move score is nearly one piece down. 3rd exclamation is very important which shows that unaided computer analysis is too weak than human aided analysis. Move no 20.exd5 is mostly recommended by all top programs. But my post mortem analysis showed that Bxg7!! wins straight forward.

In that last game, Black's opening play immediately looked dubious to me (maybe like some games from the 1950s in which Black got killed); such play is indeed given in books as clearly better for White.

After 12..Qc8 I think 13.Bd4 looks very interesting. I don't know if it has been played.

To my mind 14.Bxe5 is a threat. A critical variation therefore might be 14..Nc6 15.Bg1 Nd7 16.h4 Ne5 17.f4 Nc4 18.Qd3 b5

Instead of 12.-Qc8 and 12.-Rc8 Black also has 12.-Qa5 which was not analyzed by Breder. In a corr game I failed to demonstrate a white advantage.

[Round "?"]
[White "Schroeder, Christoph"]

I guess it does fit very well with the modern trend of not really trying terribly hard to mate black Smiley

From that perspective unsurprising its not a terrible move - you're getting the bishop pair for starters.

I thought 9..Nxd4 10.Bxd4 Be6 11.0-0-0 Kb1 12.Rfc8 a3 13.Rab8 g5 14.Nh5 Nd5 15.Qxd2 Rxd2 was white's best in this variation, although I haven't kept myself very updated.

The older, the better - over 2200 and still rising.

What are the critical lines?
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 O-O 8. Qd2 Nc6 9. g4 Be6 10. Nxe6 fxe6 11. O-O-O Ne5 12. Be2 Qc8 13. Kb1

Engines want to play immediate Nc4 instead of Golubevs Nfd7 if 12...Qc8 is better try for black.

Thanks, I will have a closer look later but I can agree that Nxe6 lines is at least more ambitious than the usual dull endgames resulting from 9 g4.


Have look a bit closer, the line is in fact serious winning try (maybee even better than 9 0-0-0 these days) and has been negacted by theory. Both sides will get lots of play, maybee white has the slightly better prospecs.

In the 9...Be6 variation, 10.Nxe6 has a better reputation than 10.0-0-0
According to C. Hansen white has the edge in this rather sharp position with the themeatic h4/h5


That was big news to me. since the positon has been considered equal (or good for black) there since at least 1990:s..


Maybe 10 Nxe6 is coming into fashion and is due for a reappraisal. Vallejo has played it twice, including last week in Gibraltar (attached).
