This opening creates a clean central struggle right away. As Black, you have challenged White’s centre with 3...c5 and reached a position where the engine calls things dead level. That is a good sign if you like active defence: you are not worse, but you do need to stay accurate. Your job is to meet White’s natural central ideas with sound development and timely exchanges, rather than waiting passively for White to seize the initiative.
The engine’s preferred move
The engine’s best move here is Ngf3. The listed continuation is Ngf3 cxd4 exd5 Qxd5, which shows the kind of position the engine expects to arise: open lines, central exchanges, and fast piece activity. For a Black player, this is useful because it points you toward a straightforward response to White’s most forcing development. In the drill, focus on staying calm and making sure your pieces keep pace with the central tension.
What the database says White usually does
The most played continuation is c3 with 277,256 games, and that is also the only listed mistake in this position. White also often chooses exd5 with 161,598 games, Ngf3 with 152,647 games, dxc5 with 27,606 games, Bb5+ with 11,611 games, and Ne2 with 4,656 games. The big takeaway is that White has several plausible tries, so you should know the position rather than rely on one memorised line. Against the most common choice, be ready to punish looseness and keep the centre under control.
The main mistake to know
The known mistake is c3, which is an inaccuracy and loses about half a pawn; Ngf3 was better. That matters because many players use c3 to support the centre, but in this exact position it is not the most precise move. As Black, this is your signal to stay alert for small advantages when White delays piece activity or plays too softly. If White makes this mistake, do not rush — use the opening of the position to develop naturally and keep the pressure on the centre.
