Chess: Understanding the French Defense (Transpositionally) Part III

1 d4 d5 2 Nc3 Nc6 3 e4 Nf6 4 e5 Ng8 5 Nf3 Bg4
6 Be2 e6 7 O-O Nge7 8 Nh4 Bxe2 9 Nxe2 Ng6

10 Nf3 Be7 11 Be3 O-O Line



What's the game plan for White?

* Establish a d4-e5 pawn chain and solidify
its d4 base. The advance c2-c3 works well
towards that end.
* Where possible, re-develop the f3 knight,
and then take a swipe at the base of Black's
pawn chain via f2-f4-f5.

What's the game plan for Black?



* Entice White into releasing the d5 tension.
Once that's achieved, Black can delay the
solidifying ... e6 until after the light-squared
bishop is developed.
* Aim for a timely ... c5 and ... f6. The idea
is to disrupt White's central pawn chain.

The d5 pawn is now attacked twice, but,
it's protected only once.

3 g3 Nf6 4 Bg2.

3 ... Nf6



The best form of defense is offense.
White's e4 pawn is about to be captured.

4 e5



Attacking the attacker and also gaining ground.

4 exd5
4 f3


4 ... Ng8



On the outset this move looks regressive.
However, the knight has persuaded White
to relinquish the d5 pressure, thereby
enabling Black to delay the solidifying
... e6 until after the light squared
bishop is mobilized. Moreover, the
knight can always be brought back
into the game via Ng8-e7-g6.

9 ... Ng6



And the knight is back in the game.

9 ... Qd7

Avoiding capture and also reinforcing d4,
together with the Queen and e2 knight.

What's the game plan for White?

* Sacrifice the e4 pawn in order to enable d4-d5.
The idea is to cramp Black's game in the center.

What's the game plan for Black?



* Loosen White's grip on the center via ... c7-c5.
This thrust obligates White to capture en passant
on c6, otherwise ... c5-c4 will suffocate his
queenside.

6 Qe2
6 Qd2
6 Nge2


6 ... a6



Preparation for ... b5. The impending pawn storm
is intended to destabilze the c4 bishop and

at two of its key defenders.
