Bishop's Opening
Quick reference
1.e4 e5 2.Bc4 develops the light-squared bishop toward f7 before touching the knight at all, which is one move earlier than the far more common 2.Nf3. It isn't a distinct strategic system so much as a deliberate reordering of moves that are going to be played anyway in most lines — and that reordering is the entire reason to know about it.
What the move order actually buys
Delaying Nf3 keeps the f-pawn free to advance to f4 in some lines, something the standard Italian Game move order rules out once the knight has already claimed f3. It also lets White react to Black's second move rather than committing to Nf3 blind — against 2...Nf6, for instance, White can choose a calm 3.d3 or a sharper line without having already told Black which knight development is coming.
Where it usually ends up
In most practical games, this transposes directly into standard territory once White plays Nf3 on a later move — reaching an ordinary Italian Game or Giuoco Piano position, just arrived at from a slightly different direction. The lines that stay genuinely distinct are the ones where White follows up with an early Nc3 and a kingside pawn storm instead, or meets 2...Nf6 with 3.d4, opening the center immediately rather than developing quietly — these keep the Bishop's Opening feeling meaningfully different rather than just a relabeled Italian.
Your Italian Game knowledge already covers this
Don't treat this as an unfamiliar opening requiring separate preparation — in the overwhelming majority of lines, playing solid, principled moves (develop, castle, contest the center) reaches exactly the kind of position your existing Italian Game or Two Knights knowledge already covers.

Frequently Asked Questions
Is this the oldest recorded chess opening?
It's among the oldest to be studied in writing — it appears in Italian analysis from the 16th century, predating most of the theory built around 2.Nf3. That historical pedigree is a large part of why it kept its own name rather than being absorbed entirely into the Italian Game.
What's the most testing reply for Black?
2...Nf6, counterattacking e4 immediately, is generally considered the most challenging response — it forces White to make a real decision (defend e4 with d3, or allow complications with something sharper) rather than just mirroring development.
Does the Bishop's Opening ever avoid transposing to the Italian entirely?
Yes — lines where White develops the queen's knight to c3 and aims for an early f4, or plays d4 to strike the center directly, stay outside standard Italian theory and require their own separate preparation rather than folding back into more common lines.
