Sokolsky Opening: c6 – A Surprising Weapon After 1.b4
The Sokolsky Opening (1.b4) is an offbeat way to start the game, and when Black answers with 1...c6 2.e3 we reach a quiet but tricky position. Stockfish calls this dead level at -0.18, a tiny edge for Black — which means you are not worse at all. With 10,929 games in the database showing nearly balanced results (White scores 47.1% wins, Black 48.8%), this line is perfectly playable for club players who want to avoid deep theory. The engine's top choice for Black is 2...d5, and how you handle that central push will decide the flavour of the game. The drill below lets you practise the key responses and learn what to look for.

Starting with 1.b4 stakes a claim on the queenside, but it doesn't mean you should neglect the centre. After 1.b4 c6 2.e3, you are preparing to develop your bishop to b2 while keeping the option of a later c4 or d4 push. Black's most common reply — by a huge margin — is 2...d5 (played in 7,649 of the 10,929 games in the database). This move claims space in the centre and prepares natural development. Your job is to continue calmly: the engine's recommended line is 3.Bb2 Nf6 4.c4, challenging Black's d5-pawn directly. The resulting positions are solid and often lead to a slow, strategic struggle where your b2-bishop can become a long-term asset.
The Engine's Best Line: A Model Development Plan
When Black plays the principled 2...d5, the engine suggests 3.Bb2 Nf6 4.c4. Let's look at each move: 3.Bb2 develops the bishop to a strong diagonal, eyeing the dark squares on the kingside. After 3...Nf6 (a natural developing move for Black), you play 4.c4 — challenging Black's centre head-on. This is a healthy approach: you are not just pushing pawns randomly but following standard chess principles (develop, fight for the centre). From here the game can take many shapes, but you will have a solid structure and your pieces will be active. If Black deviates with something other than d5, you can still rely on the same plan: fianchetto the bishop, develop your knights, and castle quickly.
Black's Most Popular Replies (and How They Score)
While 2...d5 is the overwhelming favourite (7,649 games, White scores 46.4%), Black has several other options you should know about. Here are the most-played alternatives and how you fare against them: 2...d6 (585 games, White scores 46.5%) — a quieter setup where Black prepares ...e5; 2...e6 (540 games, White scores 54.8%) — this is actually your best-scoring reply, so be encouraged if Black chooses this; 2...e5 (418 games, White scores 46.4%) — a more aggressive try; 2...Nf6 (338 games, White scores 45.3%). In every case, your plan stays the same: develop the bishop to b2, play c4 when possible, and aim for a flexible pawn centre. None of these replies refutes the opening — the scores are close across the board.
One Mistake to Punish: Qb6
The statistics reveal an important trap to watch for. The line 2...Qb6 has been played 353 times (White scores 46.7%), but the engine flags it as a clear inaccuracy that costs Black roughly 0.6 pawns. The problem is that the queen comes out too early, giving you a chance to gain time by attacking it. The correct response according to the engine is simply 3.d5 — which was Black's best move anyway, and now you are playing it with a tempo advantage because Black's queen is awkwardly placed on b6. If Black instead plays something like 2...Qb6 and you respond with 3.Bb2, you are still fine, but 3.d5 is the most punishing follow-up. Remember this sequence: if you see 2...Qb6, push 3.d5 and enjoy the extra space.
