Chess: Understanding the French Defense (Transpositionally) Part I

1 d4 Nc6 2 Nc3 d5 3 e4 e6 4 Nf3 Nf6 5 Bg5 Be7
6 Bxf6 Bxf6 7 Bb5 O-O 8 O-O Rb8 9 e5 Be7 Line




What's the game plan for White?

White pushes e2-e4 followed by e4-e5.
The idea is to enforce a central clamp.
For the future, he plans to fortify d4
(Nc3-e2 followed by c2-c3), and, if
possible, advance f2-f4-f5 in order to
undermine Black's pawn chain at its
base.

What's the game plan for Black?



Black fights for e4 and also sets himself up
for a timely ... c5 and ... f6.
The idea is to
disrupt White's pawn chain.
