Interesting. A few years ago I looked at this via 4.Bd3 Nc6 5.c3 Bd6 6.Nf3 from Black's perspective and concluded that White has the better attacking chances after 10.b4, ie castling queenside is too risky. Then I looked at 9...f6 (iso 9...O-O-O) and concluded that Black's best is castling kingside followed by ...Bf5. Finally I wondered if Black can save a tempo with 6...Nge7 (iso 6...Bg4) followed by 7...Bf5 as pointed out by GM Moskalenko in his latest book on the French; only after 7.Qc2 Black plays Bg4 as in Braga-Moskalenko, Barbera 2001. Black claims to play an improved version of the Thavandiran-So game, because Qc2 is a suboptimal move.
Just my two SRD (worth less than ever in this time of inflation).
Which book is Moskalenko's latest? Fishbein has in his bibliography Moskalenko (2015)
The Even More Flexible French.
1.e4 e6 2.d4 d5 3.exd5 Spraggett says "!". For some strange reasons I am interested in this line for white. One contributor is an important tournament I played as a junior, which I won because of three games in the Exchange French, none of which involved me! In the second one, the top-ranked player was held to a draw, later allowing me to finish 1/2-point in first. Yet objectively the move deserves "?!" because it gives away all white's positional advantage and reduces it strictly to the first move. It's an uncommon case of an opening I have looked at a lot, yet played hardly ever. However it's not completely a wasted effort -- my record on the black side of the Exchange French is outstanding.
3...exd5 4.Nf3 Nc6 5.c3 Fishbein has
- 5.Bb5 - 6 games
- 5.c3/5.Bd3 - 3 games
- 5.Nc3!? - 3 games
- 5.h3!? - 1 game
This is the only place in the book, except for the Introduction (chapter 1), where he gives more than one line for white. I speculate that previously he played 5.Bb5 and now he doesn't really have an answer.
5.Bd3 Bg4 6.O-O Bd6 Fressinet - Short move order, I was sure must have been a typo, or a double-inaccuracy in a rapid game, but no: 6...Nxd4 7.Qe1+ Ne6 8.Ne5 +=. Should the GM have mentioned this? Perhaps he just expects *all* his readers to be able to figure this out with an engine's help.
5...Bd6 6.Bd3 Nge7 7.O-O Bg4 This is the Stojchev - Jacimovic move order. Between 5.c3/5.Bd3 and 9.Re1 Fishbein doesn't analyze any alternatives for either side, nor in his other two games in this line. 7...Bf5!? 8.Bxf5 Nxf5 9.Re1+ Nge7 I'm not sure how white should "punish" this, certainly not by 10.Qd3 O-O 11.Nbd2 Qd7 12.Nf1 when black is tempo ahead of Spraggett - Rocha (there the wN is already on g3).
8.Nbd2 Qd7 9.Re1 In the notes to Thavandiran - So, he quotes Spraggett - Rivera, Lisbon 2014, but he doesn't seem to be aware of Spraggett's article on the Exchange French. See spraggettonchess.com 2016.11.04 at archive.org.
- 9...f6 10.Nf1 O-O-O 11.b4 +/- (1:0, 57) Spraggett - Stella, Figuera da Foz 2016
- 9...O-O-O 10.b4 +/- (1:0, 59) Spraggett - Rivera, Lisbon 2014
- 9...O-O "small edge" according to Spraggett 10.Nf1 Bf5 11.Ng3 (Fishbein gives instead 11.Ne3 and 11.Be2) Bxd3 12.Qxd3 Bxg3?! 13.hxg3 (1:0, 33) Spraggett - Rocha, Ponto Delgado 2016
I wouldn't be at all surprised if 9...O-O "small edge" turns out to be "no edge". Unfortunately black won't have many winning chances with same side castling.
