King's Pawn Opening & King's Head Opening
King’s Pawn Opening
Definition
The King’s Pawn Opening is the name given to any chess opening that begins with the move 1. e4. In older descriptive notation this was “P–K4,” the pawn immediately in front of the king advancing two squares. Because the move throws a pawn into the center and frees two powerful pieces (the queen and king’s bishop), it is the cornerstone of the so-called Open Games (ECO codes C20-C99).
Typical Usage and Continuations
- Classical reply 1…e5 – leads to the Ruy Lopez, Italian Game, Scotch Game, Petroff, Philidor, etc.
- Semi-open replies – Black answers asymmetrically with 1…c5 (Sicilian), 1…e6 (French), 1…c6 (Caro-Kann), 1…d6 (Pirc/Modern), or 1…d5 (Scandinavian).
- Gambits – White may sharpen play right away: 1.e4 e5 2.f4 (King’s Gambit) or 1.e4 e5 2.d4 (Center Gambit).
Strategic and Historical Significance
By occupying the center, White claims space, gains rapid piece activity, and keeps the game tactically rich. Since the 16th century it has been the most popular first move, praised by Bobby Fischer as “Best by test.” World Champions from Steinitz to Carlsen have used it at the highest level, while entire opening systems—Sicilian, Ruy Lopez, French, and others—owe their very existence to 1.e4.
Illustrative Example
The celebrated sixth game of the 1972 World Championship match began:
Fischer’s choice of 1.e4 steered play into the Closed Ruy Lopez, culminating in one of the finest positional victories ever recorded.
Interesting Facts
- In databases of modern grand-master games, roughly half still begin with 1.e4 despite decades of deep computer preparation in alternative first moves such as 1.d4 and 1.Nf3.
- Because both queens are brought into play quickly, Open Games after 1.e4 e5 historically produced most of the early mating patterns and names (e.g., Evans, King’s, and Danish Gambits).
- The entire A-through-C volume of ECO is effectively the story of how elite players have tried to prove or refute the soundness of 1.e4 over 150 years.
King’s Head Opening
Definition
The King’s Head Opening is an irregular opening that starts with 1. f3. The move was christened in 19th-century literature because the pawn in front of the king’s “head” (its diagonal support square f2) advances. Modern manuals usually file it under the Barnes Opening (ECO A00), but the older name still appears in historical sources and problem-solving circles.
Why 1.f3 Is Rarely Seen
- Weakens the king. Removing the f-pawn opens the longest light-squared diagonal toward the king (e1–h4).
- Neglects the center. Unlike 1.e4 or 1.d4, it claims no space and permits Black to occupy central squares unhindered.
- Blocks piece development. The natural square for the king’s knight (g1–f3) is taken away.
Strategic & Historical Notes
Because of those drawbacks, 1.f3 is almost never employed in serious competition. Its main historical significance lies in cautionary tales about opening principles and in composing the quickest possible mate (Fool’s Mate).

Henry Bird (then experimenting) opened 1.f3 and was punished by the first World Champion after 1…e5 2.Kf2 d5!
Contemporary Usage
Nowadays the King’s Head Opening is encountered mainly in:
- Blitz or bullet games where surprise value outweighs soundness.
- Handicap games or exhibitions where a master gives odds.
- Puzzle compositions that illustrate mating nets on the weakened e1–h4 diagonal.
Interesting Facts
- The opening can transpose into a kind of Reversed King’s Indian if White later plays g3, Bg2, and d3—but with a permanently compromised king.
- Because 1.f3 is so rare, its statistical score in databases is misleadingly high in very small sample sizes; strong engines evaluate the starting position at roughly –0.80 (!).
- In some scholastic events the move is jokingly called the “Fire Alarm” because coaches rush in to stop students from playing it.
