Quick answer
French Advance is an opening choice: French Advance move order and resulting pawn structure. Work from the first evidence position for French Advance, and begin by testing c4.
Begin from c4 in rnbqkbnr/ppp2p1p/4p3/3pP1p1/3P4/8/PPP2PPP/RNBQKBNR w KQkq - 0 4. Read the first contact, the development debt and the pawn break that the move order makes possible. The evidence answer is: French Advance: read the move order as a set of development and pawn-break decisions, then compare the opponent's most direct reply. Candidate line: c4.
In the French Advance example, notice: side White; pieces Black rook a8, Black knight b8, Black bishop c8, Black queen d8, Black king e8, Black bishop f8, Black knight g8, Black rook h8, Black pawn a7, Black pawn b7, Black pawn c7, Black pawn f7, Black pawn h7, Black pawn e6, Black pawn d5, White pawn e5, Black pawn g5, White pawn d4, White pawn a2, White pawn b2, White pawn c2, White pawn f2, White pawn g2, White pawn h2, White rook a1, White knight b1, White bishop c1, White queen d1, White king e1, White bishop f1, White knight g1, White rook h1; legal first moves a3, a4, b3, b4, c3, c4, f3, f4. Treat this piece list as local to the diagram above; it is not a universal map for every similar position.
What the position is testing
The first evidence board tests French Advance move order and resulting pawn structure; the second board tests French Advance move order and resulting pawn structure. A opens with the string e4 e6 d4 d5 e5 g5, whereas B opens with e4 e6 d4 g6 d5. Background terms live on the Chess Wiki and the Openings hub. Then compare Opening Principles with Caro Kann Panov, French Exchange, French Winawer around a delayed pawn break.
The two inventories make the distinction concrete. A contains side White; pieces Black rook a8, Black knight b8, Black bishop c8, Black queen d8, Black king e8, Black bishop f8, Black knight g8, Black rook h8, Black pawn a7, Black pawn b7, Black pawn c7, Black pawn f7, Black pawn h7, Black pawn e6, Black pawn d5, White pawn e5, Black pawn g5, White pawn d4, White pawn a2, White pawn b2, White pawn c2, White pawn f2, White pawn g2, White pawn h2, White rook a1, White knight b1, White bishop c1, White queen d1, White king e1, White bishop f1, White knight g1, White rook h1; legal first moves a3, a4, b3, b4, c3, c4, f3, f4; B contains side Black; pieces Black rook a8, Black knight b8, Black bishop c8, Black queen d8, Black king e8, Black bishop f8, Black knight g8, Black rook h8, Black pawn a7, Black pawn b7, Black pawn c7, Black pawn d7, Black pawn f7, Black pawn h7, Black pawn e6, Black pawn g6, White pawn d5, White pawn e4, White pawn a2, White pawn b2, White pawn c2, White pawn f2, White pawn g2, White pawn h2, White rook a1, White knight b1, White bishop c1, White queen d1, White king e1, White bishop f1, White knight g1, White rook h1; legal first moves Nc6, Na6, Qe7, Qf6, Qg5, Qh4, Ke7, Bg7. Compare the side to move before comparing the labels in the context of the first long-term target.
Topic dossier for this page and board pair r1:rnbqkbnr | r2:ppp2p1p | r3:4p3 | r4:3pP1p1 | r5:3P4 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR / r1:rnbqkbnr | r2:pppp1p1p | r3:4p1p1 | r4:3P4 | r5:4P3 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR: start with a delayed pawn break; then test the first long-term target; keep the route to a familiar endgame separate from space gained by the first contact; use a forcing reply before development is complete as the transfer check; and reserve simplification versus initiative for the exception.
Move order and plan
On the first board, calculate c4 after c4 and write down the opponent's best reply around a delayed pawn break. On the second board, calculate Nc6 after Nc6 and check the first long-term target. Compare the first plan for both sides before choosing a move from memory; the same opening name can lead to different positions after one exchange. In this case the useful condition is simplification versus initiative.
Key claim: French Advance is illustrated here by French Advance move order and resulting pawn structure; the first concrete test is c4. The board anchor is rnbqkbnr/ppp2p1p/4p3/3pP1p1/3P4/8/PPP2PPP/RNBQKBNR; the example is intentionally narrower than the topic label and should not be generalised without checking the surrounding position..
Practical boundary: To answer “Which move-order choices, plans, and pawn breaks make french advance useful in a real game?”, compare the recorded setup with Nc6 and the opponent's reply. The decision is useful only when the stated condition survives that concrete test on board rnbqkbnr/pppp1p1p/4p1p1/3P4/4P3/8/PPP2PPP/RNBQKBNR. The evidence records Illustrative move-order evidence; no opening score, engine evaluation, or popularity claim is asserted and the second board signature r1:rnbqkbnr | r2:pppp1p1p | r3:4p1p1 | r4:3P4 | r5:4P3 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR. The false-positive test is whether the route to a familiar endgame appears without space gained by the first contact, so the conclusion is useful only when the stated condition survives that concrete test.

Reading the line
Read the first example (id example-1) as a complete record: continuation c4, source opening-database. The reproducible setup is e4 e6 d4 d5 e5 g5 with board anchor rnbqkbnr/ppp2p1p/4p3/3pP1p1/3P4/8/PPP2PPP/RNBQKBNR; replay it before treating the board as an abstract illustration. If A does not expose French Advance move order and resulting pawn structure, correct the evidence before relying on the prose.
Read the second example (id example-2) separately: continuation Nc6, source opening-database. Its feature is French Advance move order and resulting pawn structure; inventory side Black; pieces Black rook a8, Black knight b8, Black bishop c8, Black queen d8, Black king e8, Black bishop f8, Black knight g8, Black rook h8, Black pawn a7, Black pawn b7, Black pawn c7, Black pawn d7, Black pawn f7, Black pawn h7, Black pawn e6, Black pawn g6, White pawn d5, White pawn e4, White pawn a2, White pawn b2, White pawn c2, White pawn f2, White pawn g2, White pawn h2, White rook a1, White knight b1, White bishop c1, White queen d1, White king e1, White bishop f1, White knight g1, White rook h1; legal first moves Nc6, Na6, Qe7, Qf6, Qg5, Qh4, Ke7, Bg7. Compare what changes between c4 and Nc6.
Where the idea stops
The main mistake to avoid with French Advance is memorising a sequence without checking which move changes the strategic problem. In A, the missing condition must be located in r1:rnbqkbnr | r2:ppp2p1p | r3:4p3 | r4:3pP1p1 | r5:3P4 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR after c4; in B, test it against r1:rnbqkbnr | r2:pppp1p1p | r3:4p1p1 | r4:3P4 | r5:4P3 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR after Nc6.
For French Advance, the first board's evidence boundary (after c4) is Illustrative move-order evidence; no opening score, engine evaluation, or popularity claim is asserted. The second board's evidence boundary for French Advance is Illustrative move-order evidence; no opening score, engine evaluation, or popularity claim is asserted. If a trusted source or careful calculation changes the conclusion around a forcing reply before development is complete, update both the evidence record and this article.
Practice from a real game
replay the recorded move order, pause before the first irreversible pawn move, and write one plan for each side. Start with A's side to move and r1:rnbqkbnr | r2:ppp2p1p | r3:4p3 | r4:3pP1p1 | r5:3P4 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR; record two candidates, the reply to c4 and the correction. Repeat with B's side to move and r1:rnbqkbnr | r2:pppp1p1p | r3:4p1p1 | r4:3P4 | r5:4P3 | r6:8 | r7:PPP2PPP | r8:RNBQKBNR; the changed board tests transfer rather than diagram memory.
After the drill, compare your notes with Caro Kann Panov, French Exchange, French Winawer through space gained by the first contact. Keep A's rejected alternative beside B's chosen line Nc6; this shows whether the conclusion survived a new board signature.
