About this opening
The O'Kelly Defense (4.f3 c6) declines the capture on f3 and supports a future ...d5 or ...Bf5 in the Caro-Kann spirit. Black aims for a solid structure and the eventual return of the pawn to neutralize the attack. Modest but sound, this reply denies the Blackmar-Diemer targets and allows harmonious development away from the complications.
