Scotch Game: Bd6 – Seize Your Advantage as White

Black's third move 3...Bd6 looks natural — develop a piece, defend the pawn — but it leaves the e5-pawn vulnerable to a simple tactical strike. You take it: 4.Nxe5. Black cannot recapture immediately because the knight on c6 is pinned to the queen by your own queen on d1. After 4...Nxe5 (the most common reply, seen in 1,480 of the 2,314 games in the database), you play 5.dxe5, and when Black recaptures with 5...Bxe5 you hit back with 6.Bxe5. From here Black's best follow-up is 6...f4 — a solid continuation — but you have already won a tempo and ruined Black's coordination. The engine gives you +0.84, a clear and lasting edge.

At first glance the raw results look alarming: across 2,314 games Black wins 51.1% and White only 44.9% (with 4.0% draws). That is a lower White winning percentage than the evaluation suggests it should be. The reason? Many White players in the database do not find the accurate continuation. When White chooses the correct 4.Nxe5, White scores 43.1% — still below expected — but look closer. Among the rarer moves White scores far better: after 4...Nf6 (a mistake) White wins 58.8%, and after 4...f6 (a blunder) a massive 66.7%. The lesson is clear: if you know the theory and avoid the common inaccuracies yourself, your results will far outpace the overall average.

Black has several ways to go wrong on move four, and you need to know how each one changes your plan. The most common mistake is 4...Bxe5, seen in 770 games. This is classified as an inaccuracy — Black loses about 0.8 pawns. You simply recapture 5.dxe5, and White has the bishop pair and a space advantage. Much worse is 4...Nf6, a mistake costing roughly 2.2 pawns. Black tries to develop and attack your knight, but after 5.Nxc6 you are up a clean pawn with a dominating centre. The worst offender is 4...f6, a blunder that loses about 4.6 pawns. Here 5.Nxc6 wins the piece — the pawn on f6 cannot recapture because it would hang the queen on d8. Keep your eyes open for these replies and you will convert easily.

If your opponent plays accurately and chooses 4...Nxe5, the engine's best line runs: 4...Nxe5 5.dxe5 Bxe5 6.Bxe5 f4. Black pushes the f-pawn to challenge your bishop and create some kingside space. You should retreat the bishop — to g3, d4, or c3 depending on taste — and continue developing with Nc3 and Be3 or Bg5, aiming for a quick O-O-O or O-O. You have the bishop pair, a lead in development, and Black's bishop is already traded off. Your plan is simple: finish development, control d4 and d5, and break open the centre when ready. The advantage is real and lasting, but it will not win itself — keep playing actively.
