Defensa francese
instantia de: chess opening[*]
subclasse de: King's Pawn Game[*]










Le defensa francese es un apertura de chacos. Illo es characterisate per le movimento:


 1.e4 e6

Illo ha un reputation de soliditate e flexibilitate, sed illo pote resultar un joco crampate pro le jocator nigre in le prime stadios. Le jocator nigre frequentemente gania contra-attaccar possibilitates in le latere del regina (dama) durante que le jocator blanc tende a concentrar in le latere del rege.


Le defensa es nominate post un partita per correspondentia jocate inter le citates de London e Paris in 1834. Como replica a 1.e4, le francese recipeva relativamente pauc attention in le seculo 19 comparate a 1...e5. Le prime champion mundial de chacos Wilhelm Steinitz diceva "Io nunquam in mi vita ha jocate le defensa francese, le qual es le plus obtuse de tote le aperturas". [1]
