French Connection

The French Connection arises after 1. e4 Nc6 2. Nc3 e6, a name used in the Lichess and Chess.com opening books. Rather than allowing the Vienna Game with 2...e5, Black adopts a French-type pawn on e6. The cost is that the knight on c6 stands in front of the c-pawn, so the ...c5 break that normally challenges White's center in the French is unavailable. Black must instead look for counterplay through piece pressure and other pawn breaks, and the structure often feels more cramped than a standard French.

White has several ways to proceed. The most common reply is 3. Nf3, simple development that keeps options open. 3. d4 occupies the center directly and is the engine's first choice; it scores slightly better for White than the alternatives. 3. Bc4 places the bishop on the a2–g8 diagonal, although Black has done comparatively well against it. The engine gives White a slight edge, and practical results are fairly close, with White scoring somewhat more. The line is a modest sideline of the Nimzowitsch, seen mostly in online play.
