Bird's Opening

Bird's Opening starts 1. f4. White takes control of the e5 square from the side, as in a Dutch Defense with colours reversed. The move loosens the diagonal toward White's own king a little, so care is needed. From's Gambit, 1...e5, is Black's sharpest reply and sets an early trap.

Ideas for White

  • Nf3, e3 and b3 with Bb2 give a firm grip on e5.
  • Against From's Gambit, after 1...e5 2. fxe5 d6 3. exd6 Bxd6, play 4. Nf3: it stops the queen check on h4 and the quick mate that follows it.

Ideas for Black

  • 1...d5 is the solid reply.
