The Rapport-Jobava System (1.d4, 2.Nc3, 3.Bf4) aims to develop quickly and avoid well-trodden main lines. After Black plays 3...Bb4, your queen sortie 4.Qd3 does two things: it defends the c3-knight while preparing to support a later e4 push, and it eyes the h7-square on the kingside. Black's most popular reply is 4...Nf6 (33,686 games in the database), which is also the engine's top choice. The position is dead level at +0.16, so don't expect a cheap win — but do expect that one mistake from Black can hand you a clear edge.
The Engine's Best Continuation
After Black's best answer, 4...Nf6, the engine recommends 5.a3, immediately asking the bishop on b4 what it intends. Black's most accurate retreat is 5...Bd6, and after 6.Bxd6 Qxd6 you have traded your light-squared bishop for Black's dark-squared one, slightly easing the pressure on your centre. This line is well-tested and keeps the position balanced. Practise it in the drill below so you're ready when Black plays the most principled move.
Punish Black's Mistakes
Two of Black's most natural-looking replies are actually inaccuracies that cost roughly a full pawn. Let's look at each: - 4...Bxc3+ (26,576 games): Taking on c3 immediately may seem logical — trade bishop for knight and double White's c-pawns. But the engine calls this an inaccuracy (better was Nf6). After 5.bxc3, White has the bishop pair and a half-open b-file. White scores 52.9% from this position. - 4...a6 (3,880 games): This waiting move is also a mistake (better was Nf6). It does nothing to develop or challenge White's centre. The engine says Black loses about a pawn of advantage here. Both of these moves give you the chance to play with extra space and activity. The drill will show you the engine's punishing replies.
Facing the Other Common Replies
Black has several other reasonable options you should be ready for: - 4...Nc6 (18,122 games, White scores 51.1%): Natural development. White can continue with a3 or other flexible moves. - 4...Ne7 (2,504 games, White scores 52.1%): An unusual knight development that keeps the bishop on b4. - 4...c5 (2,175 games, White scores 52.5%): A direct strike at the centre. In each case, the engine considers 5.a3 a sensible reply, asking the bishop to declare its intentions. The drill below adapts to whatever Black plays, so you'll get targeted practice against each of these moves.
