French Advance Variation tactics

A locked pawn chain, a base at d4, and a whole opening that reduces to one argument about whether that pawn holds.

What the Advance French produces tactically

White plays e5 and gains space; the pawns lock; Black immediately attacks the base of the chain with ...c5, and later with ...f6. Every piece on the board is then deployed to support or undermine the pawn on d4. It is the clearest example in chess of a position where you can state the plan for both sides in a sentence and still lose it.

The tactics fall into two families. Black's arrive when d4 collapses: a piece landing on b4, f5 or e4 while the queen watches b2, or the whole centre falling apart because the defender of d4 got deflected. White's come from the space advantage, most famously the bishop sacrifice on h7 once the black king has castled into a position where the pieces cannot get back.

Both plans, and the timing that decides them

Black's counterplay is not optional here. Space advantages get worse with every move that does not challenge them, so ...c5 and the pressure on d4 have to start immediately. Players who develop first and attack later end up in a French with no counterplay, which is the worst position the opening offers.

White's error is the opposite: pushing pawns past their support. The e5 pawn is an asset while it is defended and a permanent weakness the moment it is not, and the same is true of a d4 pawn advanced to d5 before the pieces have arrived.

Questions people ask

How does Black attack the pawn chain in the French?

At its base. The chain runs from d4 to e5, so the base is d4, and ...c5 attacks it directly. Later ...f6 attacks the head from the other side. Attacking the front pawn first is the standard beginner error.

Is the Advance Variation good against the French?

It is a solid main line and it has the practical advantage of producing one structure you can learn thoroughly. It does not refute anything -- Black gets a normal share of the play with accurate handling of the ...c5 break.
