The Owen’s Defense arises after 1.e4 b6 and falls under ECO code B00. Named after the 19th-century English player John Owen, this uncommon reply to 1.e4 allows White to seize the center effortlessly with 2. d4, which is the standard and most natural response. Black’s plan is typically to fianchetto the dark-squared bishop to b7, aiming for long-diagonal pressure.
