Caro-Kann Defense: Euwe Attack — White’s 2.b3
After 1.e4 c6 2.b3, you are aiming for a flexible setup rather than an early all-out attack. The position is already unusual, and Black has a simple, strong response ready. In the drill below, you will practise what to do when Black chooses the most tested reply, how to react to the main alternatives, and how to avoid the moves that let your edge slip away. Treat this as a practical test of development, central control, and patience.

Stockfish rates this -0.27, a small plus for Black. That means you are slightly worse here. So this opening is not a claim that White is better right away; it is a sideline where you need to prove that 2.b3 has a clear idea behind it. The good news is that the position is still playable, and the database shows many games reaching it. Your job is to handle the resulting middlegame sensibly, not to force tactics that are not there.
Black’s most important reply
The engine’s best move is d5, and the most-played continuation is also d5. That is the move you should expect most often in the drill. Black’s central strike is the critical moment of the opening: if you are slow, Black takes the initiative in the centre and your queenside fianchetto setup has to justify itself. Against this reply, keep your development orderly and remember that the centre is the real battleground.
What the database says to expect
This exact position has been reached in 346,531 games at the Lichess database, so you are not learning a rare curiosity. Across those games, White wins 46.2%, draws 3.7%, and Black wins 50.1%. The most-played continuations after the opening moves are d5, d6, e6, e5, Nf6, and g6. That spread tells you two things: Black has several reasonable ways to answer, and you need to be comfortable meeting more than one defensive setup.
The moves that are easiest to punish
Three replies are marked as inaccuracies here: d6, e6, and g6. The database and engine both point to d5 as the stronger choice, so those alternatives are the ones you should handle with confidence in the drill. In practical terms, do not treat every king-side or pawn-push setup by Black as equally sound. When Black chooses one of these slower moves, stay focused on development and do not drift into passive piece placement.
How to use this opening as White
This line suits you if you want a flexible, offbeat way to meet the Caro-Kann without forcing a sharp theoretical battle. But flexibility comes with a price: Black’s central play is straightforward, and the position is already a little better for your opponent according to the engine. So the right mindset is practical rather than ambitious. Build your pieces, respect the centre, and use the drill to learn the best responses until they feel automatic.
