Owen Defense: d3 — Playing Black After 1.e4 b6 2.d3 e5

By playing 1...b6 followed by 2...e5, you're aiming for a solid but slightly passive French-like structure with your light-squared bishop fianchettoed. The engine assesses this position at +0.55, a small edge for White, meaning you are slightly worse out of the opening — but this is perfectly playable at club level. Your bishop on b7 eyes the centre and will often trade itself for a knight on f3 or bear down on the e4 pawn if White pushes f4. In the 98,323 games reaching this exact position, Black scores a healthy 45.5% wins (with 4.1% draws), showing that the Owen Defense is no pushover.

Stockfish's top recommendation for White here is f4. After f4 Nc6 Nf3 exf4, White is aiming to open the centre and exploit Black's slightly lagging development. This is the line you need to be most ready for as Black. You'll notice that White's f4 push is far from the most common choice in practice — it's only the third most-played move — but it poses the most theoretical challenge. In those 11,974 games where White played f4, they scored 53.2%, the highest winning percentage of any White move here. Against f4, your task is simple: capture on f4, develop your knight to c6, and trust that your bishop pair and central influence will compensate for the pawn on f4.

The most popular White move by far is Nf3 (30,567 games), but it only scores 50.6% — essentially a draw rate. That's good news for you: the main line is nothing special for White. Nc3 (13,384 games, 50.2%) and c3 (5,633 games, 50.1%) are similarly unthreatening. Be2 (6,037 games, 51.1%) is slightly more dangerous but still modest. The outlier is Be3 (5,917 games, 48.9% for White) — notice that Be3 is actually the only White move where Black outscores White! The engine confirms this is a mistake: Be3 loses about 0.8 pawns in evaluation compared to the best move f4. If your opponent plays Be3, you should be happy — you've already gained a small edge.

The FACTS identify Be3 as an inaccuracy for White. It loses roughly 0.8 pawns of advantage, dropping the evaluation from a small White edge to roughly equal or slightly better for you. Why? The bishop on e3 blocks the e-pawn and does nothing to challenge Black's setup. After Be3, your best response is natural development — Nc6, then maybe Nf6, and you'll have a comfortable game with no weaknesses. Remember: in the Owen Defense, your bishop on b7 is your star piece. Keep it active, and if White misplaces their pieces (like putting a bishop on e3), take advantage.
