Owen Defense
ECO B00 · 1. e4 b6
Owen's Defense, 1.e4 b6, fianchettoes the queen's bishop to pressure e4 along the long diagonal. It is a hypermodern idea that hands White the center in exchange for long-term pressure, named after the 19th-century English clergyman John Owen.
Plans for White
White plays d4, Bd3 and Nf3 or Nc3, protecting e4 and preparing to gain space with c4 or attack with e5. Keeping the e4 pawn well protected neutralizes the b7 bishop.
Plans for Black
Black follows with ...Bb7, ...e6 and often ...c5 or ...f5, trying to undermine the center. A French-like ...d5 is another option once White commits.
Typical pawn structures
White's e4/d4 center against Black's fianchetto and flexible center pawns; the long a8-h1 diagonal is the main battleground.
Who it suits
Players who want an unusual reply to 1.e4, enjoy hypermodern ideas and are happy to let the opponent build a center in order to attack it later.
Common traps
A careless ...f5 can be punished by exf5 and Qh5+, exploiting the weakened light squares around Black's king.
