The Rapport-Jobava System: Meeting 3...e6 and 4...c5
The Rapport-Jobava System (1.d4 d5 2.Nc3 e6 3.Bf4) has become a popular weapon for White at every level, and the most critical response is to meet 3...e6 immediately with 4.e4, bursting the centre open. After 4...c5, you reach a sharp tabiya where Black must choose how to handle the pressure on d5 and the exposed queen. Stockfish rates this +0.36 — a small edge for you — and the database of over 51,000 games shows you scoring 51.5% wins. But the key is knowing which Black replies punish themselves, and which require precise play from you. The interactive drill below will sharpen your instincts in this exact position, whether you are playing a blitz game or preparing a rapid repertoire.

The move 4.e4 is the heart of the Rapport-Jobava against 3...e6. By advancing in the centre before Black has fully developed, you challenge Black's pawn on d5 and open lines for your pieces. The bishop on f4 already eyes the queenside and the c7 square, and after 4.e4, the d5-pawn becomes a target. Black's most principled reply is to capture on d4 with the c-pawn (4...cxd4), which leads to a queen exchange and a slightly simplified middlegame. But many club players avoid this and choose moves that are statistically worse — and that is where your advantage can grow quickly.
Your Engine-Approved Continuation: 4...cxd4
The engine's top recommendation for Black is 4...cxd4, continuing with 5.Qxd4 Nc6 6.Qa4. This line keeps Black solid but leaves you with a comfortable edge (+0.36). After 6.Qa4, you have a lead in development and pressure on the queenside. You will typically follow up with ideas like 0-0-0, Nf3, and Bd3, keeping an eye on the d5-pawn. In the 15,319 games where this line was played, White scored 51.0% — a solid result that confirms you are fighting for an advantage without taking excessive risk.
Punish the Mistakes: Nc6, Nf6, and Qb6
Three common Black replies are flagged as mistakes or inaccuracies in the FACTS, and knowing how to handle them can boost your score significantly. 4...Nc6 is a mistake that costs Black roughly 1.7 pawns — the engine prefers 4...cxd4 instead, so you should be ready to seize your advantage. 4...Qb6 is also a mistake, losing about 1.3 pawns; Black attacks the b2 pawn prematurely, and you can respond with active development or simply 5.exd5 with a strong centre. 4...Nf6 is an inaccuracy (roughly 0.6 pawns), where Black develops a knight but fails to challenge your centre optimally. Against all three, the simple 5.exd5 followed by natural development (Nf3, Bd3, 0-0) often leaves Black struggling to equalise. Your score against 4...Nc6 is 54.2% — a clear reward for knowing the correct approach.
What the Statistics Tell You
Across 51,661 games, White wins 51.5%, draws just 3.0%, and Black wins 45.5%. That low draw rate is typical of sharp opening systems — games tend to be decisive. Your highest winning percentage comes against 4...Nc6 (54.2%), while 4...Nf6 is the only reply where Black scores higher (White wins only 46.2%). If you see 4...Nf6, be alert: Black is playing one of the trickier responses and you may need to avoid over-pressing. The other popular tries — 4...dxe4 (White scores 51.4%) and 4...c4 (White scores 48.8%) — are less common but still require a calm, centralised response. Overall, the position rewards the player who knows the key ideas better, and that is exactly what this drill gives you.

Frequently asked questions
Is the Rapport-Jobava System a good opening for beginners?
Yes — the system is relatively easy to learn because White's setup (d4, Nc3, Bf4, e4) follows natural development and centre-control principles. In the 3...e6 4...c5 line, you reach a clear middlegame with an edge (+0.36) and straightforward plans: develop quickly, pressure d5, and castle on either side depending on Black's play.
What is the best move for White after 4...cxd4?
The engine recommends 5.Qxd4, followed by 5...Nc6 6.Qa4. You keep your queen active on the queenside and maintain a small advantage. In practice, White scores 51.0% from this position, and you can continue with natural development moves like Nf3, Bd3, and 0-0 or 0-0-0.
Why is 4...Nc6 a mistake in this position?
4...Nc6 blocks Black's c-pawn from capturing on d4 and leaves the d5-pawn undefended. The engine evaluates it as a mistake costing about 1.7 pawns compared to the best move 4...cxd4. From that position, White scores 54.2% — your highest win rate against any Black reply.

Yes — across 51,661 games, only 3.0% ended in a draw. The position is sharp and unbalanced, which means you will often play for a win as White. If you prefer fighting chess with plenty of chances to outplay your opponent, this is an excellent choice.
