Stockfish evaluates this position at +0.12 at depth 16, meaning a very small edge for White — so small it's essentially equal. For you as Black, that is excellent news. You are not worse; the position is balanced and full of play. The Lichess database of 63,661 games confirms this: Black scores a healthy 51.1% win rate, while White wins only 44.6% (with 4.3% draws). That is a genuine plus for Black at the club level. White's extra tempo is offset by the fact that their light-squared bishop is already committed, and Black's pieces develop naturally.
White's Best Move: The Exchange on d7
The engine's top choice is Bxd7+, giving up the bishop pair immediately. After Bxd7+ Qxd7, White usually continues with c3 and e6, locking the centre. This is the most-played continuation by a large margin — 46,743 games out of 63,661, more than any other reply. White scores only 44.8% from this line. As Black, after recapturing with the queen on d7, you have a solid position with no weaknesses. Your plan is straightforward: finish development, contest the centre, and look to pressure White's pawn on e5 later.
The Most Common Mistakes White Makes
Your opponents will often avoid the exchange, thinking they can keep the bishop. The FACTS show three clear errors in this position. Nc3 is an inaccuracy, losing about 0.8 pawns in evaluation; it has been played 5,687 times but White should have taken on d7 first. Qd3 is also an inaccuracy with the same penalty. Worst of all is Qe2, which is a full mistake, losing around 1.7 pawns. These moves let you, as Black, gain a tempo or keep the bishop pair advantage. If you see any of these from White, you can be confident you've already steered the game your way.
What to Do Against White's Other Replies
Beyond Bxd7+, White sometimes tries a4 (3,595 games, White scores 46.8%, still below average) or c4 (882 games, White scores 49.0%, the highest percentage for White but still not scary). Against a4, simply continue developing — the pawn move doesn't threaten much. Against c4, White strikes the centre immediately; keep the position lively by maintaining tension in the centre. In every case, remember that Black's overall results are positive at 51.1%. The Caro-Kann structure with the pawn on e5 gives you a comfortable French-like position but without the bad light-squared bishop, since yours has already been traded or is active.

Frequently asked questions
Is 4.Bb5+ in the Caro-Kann Advance good for White?
Stockfish evaluates the position after 4...Bd7 at +0.12, which is essentially equal. In practice from over 63,000 games, Black actually scores 51.1%, making this a perfectly fine line for Black. White's check is not dangerous if you respond with Bd7.
Should Black always play Bd7 against Bb5+?
Bd7 is the most natural and principled reply, blocking the check and offering a trade of bishops. The engine confirms it's a fine move and it is the standard theoretical continuation in this line.
What happens if White plays Qe2 instead of taking on d7?
Qe2 is actually a mistake according to the engine, losing about 1.7 pawns in evaluation. Black can simply capture on b5 or continue development. White's best reply is Bxd7+, and anything else gives Black an edge.
Why does Black win more often than White in this position?
Despite the engine evaluation being dead level, Black scores 51.1% in practice versus White's 44.6%. This may be because White's bishop check often leaves them slightly mis-coordinated, while Black develops naturally. Club-level White players also frequently make one of the known mistakes (Nc3, Qe2, Qd3).
