The classical start. The classical reply. The bishop first: out to c4, eyeing f7, before the king's knight commits. Two doors stay open that 2.Nf3 closes — the f-pawn can still advance in Vienna style, and Black's Petrov Defense, the great symmetrical equalizer, never gets the chance to exist. Modern practice usually steers back into Italian waters a move later, having filtered out the opponent's favorite defense along the way. The oldest opening in the book, reborn as move-order craft."]]
The Bishop's Opening is chess's oldest analyzed beginning and its most modern revival: the c4 bishop developed before the king's knight, a one-move reordering with two concrete dividends. The Petrov Defense — Black's symmetrical equalizing machine against 2.Nf3 — never gets to exist; and the f-pawn keeps its right to advance, holding Vienna Gambit structures in reserve. Most contemporary handling then transposes into Italian Game territory a move or two later, arriving at the familiar position with the opponent's preferred defenses filtered out en route. That is the whole modern case: same destination, curated route.
