e6
The French Defence an opening that has retained its popularity to this day.

2.d4
d5
3.Nc3
dxe4
The Rubinstein variation which has long led to diverse opinions amongst opening theorists. It gives up the centre but allows Black piece play with Nf6 and possibly b6/Bb7. It can be noted, though, that in recent years it has been played by Carlsen and Ivanchuk, and very often by Gelfand.

4.Nxe4
Nd7
Apart from this line Black has a range of other plans here such as [4...Bd7
as for instance in So-Carlsen, chess.com Blitz 2017.; 4...Nf6
for example, Ivanov-Nakamura, Philadelphia National Open 2006.; 4...Be7
as played in Magem Badal-Hodgson, FRA-tch 1999 for example.
These options indicate the position is quite flexible and can be played in different ways to suite a very diverse range of player styles.]

Other popular lines here are [7...c5

11.Rad1
Qd5
On this square the queen is somewhat exposed despite bearing down on the long diagonal to White's g2. Instead, Black can obtain a more or less equal game with the lines [11...h6
12.Bf4
Bd6
13.Ne5
; or 11...Bxf3

12.c4
Qd6
Its interesting to note this seems to have only been played in this old game. More recent games has featured, in a dozen or more games, the inferior [12...Qa5

and White has a significant edge as in Degerman-Berkell, Rilton Cup, Stockhom 1987.]

13.Ne5
Rad8
In this position Black plays a natural, but not optimum move, now White is much better once again.
Superior chances were offered by exchanging some pieces with [13...Nd7
14.Qh5
f5
15.Bxe7
Qxe7
16.Rfe1
Rad8
despite creating a weak backward pawn on e6, when White is just a little better.; Also interesting but problably not quite sufficient is 13...c5

14.Rfe1
Completing develpment which in reply Black immediately errs. White has another good line here of [14.Bf4
Qb4
15.a3
Qa4
16.Bc2
Qe8
17.Rfe1
with a space advantage although Black is fairly solid.]

14...Nd7
Now Black is struggling to stay in the game. [Instead 14...h6

Threatening mate so retarding Bxh7+ and Bxg7 ideas. [If 16...Qb4
