In theory, the idea of the knight being misplaced on the edge is fine. However you have to look at the specifics of the position to see if it's really the case - and here it isn't.

9.Ne2 is also strongly met by 9...Na5, with 10.Bd3 (or 10.Bb5 c6 11.Bd3 transposing) c5! 11.c3 Qb6 and black is better - he is already exerting pressure in the centre and on the white queenside as well as being a pawn up. 9...Ne4 looks a decent alternative as well, deploying the knight centrally and beginning active play against the d4 pawn. But 9...Na5 looks very strong to me, maybe even -/+. As always, where is the compensation?

9.d5? Na5! 10.Be2 c6! already looks close to winning to me, as white is pretty much forced to acquiesce to the queen trade with 11.dc Qxd1 12.Rxd1 Nxc6 13.Be3 Be6 where white is grovelling a pawn-down endgame. Though 11...Nxc6 might be even stronger, leaving the queens on the board and arguing that black's position might have enhanced attacking chances with them still on, eg 11...Nxc6 12.Be3 Be6 intending Qc7 and Rd8. Again black is just a clear pawn up for nothing as far as I can see.

So 9.Be3 looks like it might be the best (if not only) move. Now 9...Na5 10.Bd3 Be6 doesn't look quite so bad for white, though 11.Qe2 could be amusingly met by 11...Nh5!? laughing in the face of Tarrasch. An interesting alternative knight-to-the-edge manoeuvre could be instead 9...Ne8, intending e.g. 10.Qd2 Nd6! 11.Bd5 Nf5!? and arguing that the damage to his pawn structure isn't worth a pawn, let alone the fact black also gets the bishop pair. Black has a small edge here I would opine, though it's still a game.

As far as I can see, all of the alternatives (9.Bg5?!, 9.Ne2?, 9.d5?) are completely inadequate against correct (and non-dogmatic) defensive ideas. So I suggest we concentrate solely on 9.Be3 in trying to find lines for white here.

Trouble is, the Knight on the edge of the board risks getting trapped. But there is also 9 Ne2, which protects the d4-pawn. A timely c2-c3 should put paid to any more tricks from Black there.

I remember Zilbermints suggested 9.d5 and 9.Be3, and both are also well met by ...Na5! with some advantage for Black.

After 8...Nc6 9.Bg5, I quite like on first inspection the move 9...Na5 - again asking white where his compensation is. The point is to get rid of the bishop off the dangerous a2-g8 diagonal and then follow up with something like 10.Bd3 Be6!? intending to plant something on c4 if allowed. Hoping that white can find something to make this viable since I would consider this line myself. However, at the moment I'm again not believing in white's compensation if moves like 9...Na5 are playable.

Fair enough. I have quite a few games, so will post later.

8 h3 prevents ...Bg4 to take pressure off d4, intending to follow with Bg5 and Qd2 (as pointed out by Lane), but in my view it is too slow: 8...Nc6 (this is more to the point than 8...Nbd7 9 Qe1 Nb6 10 Bd3 c6 11 Qh4 Nbd5 12 Bh6 followed by Ng5) 9 Bg5 (or 9 Be3 Ne8 10 Qd2 Nd6 intending 11...Nf5 with pressure against d4) 9...Bf5 10 Re1 (10 Qd2 allows 10...Ne4 11 Nxe4 Bxe4 12 c3 Bd5 with a better position for Black in R.Walmisley-E.Rasmussen, correspondence 1993) 10...h6 11 Bf4 g5 12 Be3 e6 13 Ne2 Nb4 14 Bb3 Qd6 and White had no compensation for the pawn in J.Dowling-E.Rasmussen, correspondence 1993.


Thus wrote Scheerer in his new book. This can be found in the preview of his book.

It would be nice if LDZ, be it by analysis or by presenting games, would address this problem. In the meantime White should prefer 6.Bf4 and 7.Qd2.

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

To give a sample line that often pops up in over-the-board and blitz play, I show the following:

1 d4 d5 2 e4 de4 3 Nc3 Nf6 4 f3 ef3 5 Nxf3 g6 6 Bc4 Bg7 7 00 00 8 h3 Nbd7 9 Qe1 c6 10 Qh4 Nb6 11 Bb3
Bf5 12 Bh6 Nbd5 13 Ng5 Bxh6 14 Qxh6 Nxc3 15 bxc3 Qd6 16 Rae1 c5 17 g4 Qg3+ 18 Kh1 c4 19 Bxc4 Qxc3 20 gxf5 Qxc4 21 fxg6 Qd5+ 22 Re4 fxg6
23 Rxf6! with a winning advantage for White.

This new thread is dedicated to analysing games with the Studier-Zilbermints (aka Orlov's Line, Delayed Studier) Attack, 8 h3!?

The moves are 1 d4 d5 2 e4 de4 3 Nc3 Nf6 4 f3 ef3 5 Nxf3 g6 6 Bc4 Bg7 7 00 00 8 h3!?
In the coming days I will publish some of my own games with this line. There are other games that can transpose into this line after 5...g6 6 Bc4 Bg7 7 00 00 8 Qe1 Bf5 9 Qh4 Bxc2 10 h3 Nc6 11 Rf2!
