Caro-Kann Defense

also known as: 1...c6

1. e4 c6

Named after

Horatio Caro (1862–1920), an English master living in Berlin, and Marcus Kann (1820–1886), a Viennese master — who analyzed 1...c6 together.

Origin

Their joint analysis appeared in the German magazine Brüderschaft in 1886; Kann had already beaten world-class Jacques Mieses with it in 1885.

The story

Caro and Kann's modest pawn move solves the French Defense's eternal problem: Black supports ...d5 with the c-pawn instead of the e-pawn, so the light-squared bishop gets out BEFORE the door closes. For a century it wore the "solid but passive" label — then Capablanca and later Karpov showed that its solidity was a weapon, grinding wins from microscopic advantages. Modern engines adore it, and it has quietly become one of the most trusted defenses at every level, from beginners taught it for its clear plans to World Championship matches.

Why it matters

The structurally soundest reply to 1.e4: no weaknesses, free development for every piece, endgames a shade more pleasant for Black. Its price — a tempo here, a shade of passivity there — is the cheapest rent in opening theory.
