Rapport-Jobava System: The Bf5 Variation
The Rapport-Jobava System (1.d4 d5 2.Nc3 Nf6 3.Bf4) is a fun, offbeat way to steer the game away from theory. When Black answers with 3...Bf5 you reach a position that is dead level — neither side has an edge out of the opening. Your job as White is to understand the typical plans and, most importantly, to avoid handing Black an easy game. This page gives you the key ideas and a clear target: punish the most common mistake Black makes here. Ready to try it against a live engine? Jump into the drill below.

After 1.d4 d5 2.Nc3 Nf6 3.Bf4 Bf5 4.e3, Stockfish gives +0.08, a tiny edge for White that is effectively nothing. Over a massive sample of 718,403 games from Lichess, White wins 50.3%, draws 4.1%, and Black wins 45.6%. That's as balanced as an opening gets. Your goal here is not to blow Black off the board with a forced win — it's to develop sensibly, target the light-squared bishop, and trust that your understanding will outplay your opponent in the middlegame. The engine's top choice for Black is 4...c6 (preparing ...Bd3 and ...e6 exchanges), which keeps the position solid. But in practice, Black often chooses something looser.
The Most Popular Replies — and What They Tell You
Here are Black's most common continuations in the database, with your winning chances as White: - 4...e6 (440,725 games, White scores 49.0%) — Black solidifies the centre but leaves the Bf5 a bit exposed. Your plan: develop with Bd3 or Nf3, aiming to challenge that bishop. - 4...Nc6 (95,418 games, White scores 55.1%) — This is your best practical result. Black develops a knight to a square that can later clash with your c3-knight. Keep developing and look to play Bb5 or exchange on f5 when favourable. - 4...a6 (92,156 games, White scores 50.1%) — A waiting move. Black often wants to play ...b5 later. Develop normally with Nf3 and Bd3; don't let the queenside expansion distract you. - 4...c5 (11,400 games, White scores 50.9%) — This is a real mistake (see below). - 4...h6 (10,878 games, White scores 51.8%) — A random-ish move that prevents Bg5 but costs a tempo. Keep developing.
The Critical Mistake: 4...c5 — Punish It
Among the known mistakes in this position, 4...c5 stands out. According to the stats, it's an inaccuracy that loses roughly 0.9 pawns — the engine says Black should have played 4...c6 instead. Why is ...c5 so bad here? Black has already spent a tempo playing ...Bf5 and another on ...d5. Pushing ...c5 weakens the d5-pawn and opens the centre before Black is fully developed. Your plan as White is straightforward: - Take on d5 (dxc5 or exd5 lines), opening the position while you are better developed. - Bring your pieces to active squares — your bishop on f4 is already pointing at the kingside, and your knight on c3 eyes d5. - Black will struggle to catch up in development while their centre crumbles. In the drill, if Black plays ...c5, exploit it aggressively.
Your Typical Plan: Target the Light-Squared Bishop
The key feature of this position is Black's bishop on f5. It is well-placed for now, but it can become a target. Your standard developing idea is Bd3 (or, if the bishop has moved, g4 with tempo). The engine's recommended line after 4...c6 is: c6 Bd3 e6 Bxf5 — exchanging off Black's good bishop. After you trade on f5, Black's remaining bishop on c8 is bad, and you have a slight structural plus (Black often recaptures with ...exf5, giving you a target on f5). The general recipe: - Develop your kingside: Nf3, then castle short. - Challenge the Bf5 with Bd3 (or g4 after preparation). - Control the centre with a solid pawn on d4 and e3; don't push pawns recklessly. - If Black castles short, your Bf4 points toward the h7-square — a classic attacking set-up.

Frequently asked questions
Is the Rapport-Jobava System good for White?
After the Bf5 variation (1.d4 d5 2.Nc3 Nf6 3.Bf4 Bf5 4.e3), the position is dead level — the engine gives +0.08, essentially equal. White wins roughly 50.3% of games in the database, so you are not better out of the opening, but you are also not worse. It is a perfectly sound, playable opening.
What is Black's best move after 4.e3 in the Rapport-Jobava?
The engine's top choice is 4...c6, which prepares ...Bd3 and ...e6 to trade off the light-squared bishop. This is a solid, equalising line. In practice, Black most often plays 4...e6 (440,725 games in the database), which also keeps things balanced.
Is 4...c5 a mistake in this line?
Yes. Playing 4...c5 is an inaccuracy that costs Black roughly 0.9 pawns, according to engine analysis. Black should have preferred 4...c6 instead. As White, you should punish 4...c5 by opening the centre and exploiting your lead in development.
How should White develop in the Rapport-Jobava Bf5 line?
Your main plan is to challenge Black's bishop on f5. Develop with Nf3, then play Bd3 (or g4 if the bishop stays) to trade it off. After the exchange, Black's remaining bishop is bad and you have a comfortable game. Castle short and prepare kingside play.
