Move by move
- 1.e4 – White takes the center with the pawn and frees the Queen and the f1 Bishop. Against 1.e4 this course answers with the French Defense, which prepares an immediate attack on the e4 pawn.
- 1...e6 – The French Defense: the e6 pawn prepares ...d5 and supports it, so after exd5 Black can recapture with a pawn. The price is the c8 Bishop, shut in behind the e6-d5 chain.
- 2.d4 – White brings the d-pawn alongside e4 and builds the classical center: neither pawn is attacked yet and White gains space.
- 2...d5 – Black attacks e4 at once. White must choose: defend it (Nc3 or Nd2), push it (e5) or exchange it (exd5). Each choice leads to one of the course's chapters.
- 3.Nc3 – White defends e4 by developing the Knight toward the center: it is the most ambitious choice, but the Knight on c3 can be pinned by ...Bb4.
- 3...Nf6 – Classical Variation: the Knight attacks e4 and asks White to choose between e5, Bg5 and the exchange. It is more solid than the Winawer because Black keeps the dark-squared Bishop.
- 4.e5 – Steinitz Variation: White drives the Knight away and gains space; the e5 pawn will then be supported with f4.
- 4...Nfd7 – The only good retreat: from d7 the Knight supports the ...c5 break and can attack e5 with ...Nc6 or with the ...f6 push.
- 5.f4 – White supports e5 with the f-pawn and builds a huge center; in return d4 remains the weak link of the chain, attackable with ...c5 and ...Nc6.
- 5...c5 – Immediate lever at the base of the chain: d4 is defended only by the Queen and Black will bring Knight and Queen against it.
- 6.Nf3 – The Knight defends d4 and supports e5: now the white chain holds, but White's pieces are tied to its defense.
- 6...Nc6 – The Knight adds a second attack on d4 together with the c5 pawn: it is the classical pressure of the Steinitz.
- 7.Be3 – The Bishop reinforces d4, but by leaving c1 the b2 pawn is left undefended.
- 7...Qb6 – The Queen attacks b2, left undefended, and lines up on d4 behind the c5 pawn: after ...cxd4 the pressure becomes direct.
- 8.Na4 – The Knight drives the Queen away with tempo and covers b2; from a4 it also attacks c5 and b6.
- 8...Qa5+ – Intermediate check: the Queen does not retreat passively but settles on the a5-e1 diagonal, against the white King still in the center.
- 9.c3 – The c-pawn interposes and reinforces d4, but now it is pinned to the King by the a5 Queen.
- 9...cxd4 – Black exploits the pin: the c3 pawn cannot recapture on d4 because it would expose the King to the a5 Queen.
- 10.b4 – White counterattacks: the pawn attacks the Queen and closes the a5-e1 diagonal, freeing c3 from the pin.
- 10...Nxb4 – Piece sacrifice: the Knight takes b4 and closes the diagonal again. After cxb4 Bxb4+ Black will have three pawns for the Knight and the white King stuck in the center.
- 11.cxb4 – White accepts the piece; the diagonal toward e1 reopens for the black Bishop.
- 11...Bxb4+ – Check: the Bishop enters with tempo and Black already has three pawns for the Knight, including the passed d4 pawn.
- 12.Bd2 – The Bishop parries the check and offers a trade: the white King keeps the right to castle.
- 12...Bxd2+ – Black trades the Bishops with check: with fewer pieces on the board the three pawns count for more, and the a4 Knight stays far from the center.
How to exploit the position
White has a Knight for three pawns; Black has the passed d4 pawn and the white King is not yet safe, while the a4 Knight is offside.
- Play ...b6: it takes the c5 square away from the a4 Knight and prepares ...Ba6 to trade White's light-squared Bishop, leaving its King in the center.
- The d4 pawn is passed: support it with the pieces and push it when White is not coordinated.
- After ...O-O the ...f6 push attacks e5 and opens the f-file toward the white King.
- White seeks Bd3 and O-O to make the extra piece count: every tempo you take away matters.
Master tips
The triple pressure on d4: ...c5, ...Nc6 and ...Qb6
In the Steinitz, White's center rests on the d4 pawn. Keep increasing the pressure: play c5, develop Nc6, bring the Queen to b6 and then threaten the sacrifice or exchange on d4.
