Playing Black in the Danish Gambit Accepted: Svenonius Defense
The Danish Gambit is one of those openings that looks scarier than it really is. White sacrifices a pawn (sometimes two) for fast development and open lines, hoping to overwhelm you before you can catch your breath. But as Black you have a perfectly calm answer: 3...Ne7. This is the Svenonius Defense, and it politely declines to play into White's wildest fantasies. Instead of grabbing a second pawn with 3...dxc3, you simply defend the d4 pawn with your knight and dare White to prove they have compensation. Spoiler: the engine says they don't — at least not enough. The position is dead level, and the statistics across thousands of games back that up. Let's walk through what you need to know.

After 1.e4 e5 2.d4 exd4 3.c3, White hopes you'll play 3...dxc3, when the fun really begins for them. By playing 3...Ne7 instead, you refuse to open additional lines. The knight moves to a flexible square, keeping an eye on f5 and g6 while also preparing ...Ng6 to challenge a future Bc4. Critically, you still hold the d4 pawn — White must spend a move to recapture it or find something else. The engine rates the position at just +0.22, a tiny edge for White. In practical terms that means dead equal. You haven't lost the opening; you've simply asked White to show what they've got.
What White Will Probably Play
In practice, White has three main options, and you should be ready for all of them. The most common move by far is cxd4 (3,959 games), where White recaptures the pawn and the game becomes a normal centre-occupying scuffle. Next is Bc4 (3,209 games), the classic Danish development — White develops and eyes the f7 square. Third is Nf3 (1,157 games), which the engine says is actually White's best move, leading to a sequence like Nf3 d5 Bd3 dxe4. No matter which path White chooses, the stats are remarkably consistent: White scores between 51% and 54%. That's barely above average, and it tells you Black is very much in the fight.
One Move to Watch Out For (White's Mistake)
There's one continuation that might tempt you as a cheap trick — but only if your opponent gets it wrong. The move Bg5 has been played 80 times and scores a decent 53.8% for White on the board, but the engine reveals it as an inaccuracy, losing roughly 0.9 pawns of advantage. White's better move was Nf3. If you see Bg5, you can respond confidently: the pin on the knight looks awkward, but with ...f6 or even ...Nxg5 coming, White's bishop is actually misplaced. This is a good example of why the stats alone can be misleading — Bg5 scores okay in practice because club players don't punish it, but now you know better.
Your Typical Middlegame Plan
Once the dust settles, look for a few familiar themes. If White recaptured on d4, the centre is symmetrical and you can develop naturally: ...d5 (often the best reaction, as in the engine line), ...Nbc6, ...Be7, and castle short. Your knight on e7 is well placed to reroute to g6 or c6 depending on how White's pieces develop. Against Bc4, be mindful of tricks on f7 — a quick ...d5 kick is your best friend. The Danish Gambit Accepted often leaves White with a lead in development but no clear attacking plan. If you keep your cool, exchange when it helps you, and castle early, you'll reach a middle game where your extra pawn (if you held on to one) or your solid structure gives you all the chances.

Frequently asked questions
Is the Svenonius Defense a good way to face the Danish Gambit?
Yes. The engine evaluates the position at +0.22, which is essentially equal, and Black's winning percentage across thousands of games (43.7%) is healthy. By avoiding 3...dxc3 you sidestep White's most dangerous attacking lines without giving up any theoretical edge.
Why does Black play 3...Ne7 instead of 3...Nc6?
Both moves are playable, but 3...Ne7 keeps the c6 square free for the other knight, supports a future ...d5 push, and avoids the possibility of White's Bb5 pinning the knight. The knight also has a useful retreat via g6 if needed. The Svenonius Defense is a solid, slightly offbeat choice that many Danish Gambit players are less familiar with.
What is White's best move against the Svenonius Defense?
The engine recommends Nf3, preparing to meet ...d5 with Bd3 and then recapture on e4. In practice, most White players choose either cxd4 or Bc4. Both are fine for Black as long as you develop sensibly.
Is Bg5 a dangerous move for Black to face?
No — it's actually an inaccuracy. The engine says it loses about 0.9 pawns of advantage. White's best move was Nf3. If your opponent plays Bg5, you can break the pin with ...f6 or even consider ...Nxg5 in some lines. It's an opportunity, not a threat.
