Uncommon Opening - Chess Terminology
Uncommon Opening
Definition
An Uncommon Opening in chess is any opening system, variation, or first-move sequence that is played far less frequently than the mainstream, theory-rich openings such as the Ruy Lopez, Queen’s Gambit, or Sicilian Defense. While there is no single statistical cut-off, openings that appear in less than roughly 1–2 % of master-level games or that rarely feature in contemporary tournament practice are usually labeled “uncommon.” The term can apply to both White’s and Black’s choices—for instance, 1. a3 (Anderssen’s Opening) for White or 1…b5 (Polish Defense) for Black.
Why Players Use Uncommon Openings
- Surprise value: Opponents may be forced out of their home preparation as early as move 1.
- Psychological edge: An unexpected position can unsettle even a strong player.
- Specialization: Certain experts devote years to a sideline that others dismiss, scoring heavily through superior familiarity.
- Avoiding theory battles: Reduces the chance of walking into 20-move force-draw lines memorized by top grandmasters.
- Creative or stylistic preference: Some players enjoy original, off-beat structures that foster imagination rather than rote memorization.
Strategic Characteristics
Because many uncommon openings yield unusual pawn structures or piece placements, strategic plans can deviate sharply from classical principles. For example, delaying central occupation (1. g4!?—Groan Attack) or fianchettoing both bishops early (1. b3—Larsen’s Opening) leads to atypical middlegames where traditional heuristics such as “control the center with pawns” have to be re-evaluated in light of hypermodern ideas.
Historical Significance
Throughout chess history, uncommon openings have periodically risen to prominence when a charismatic player champions them:
- In the 19th century, Adolf Anderssen popularized 1. a3, winning several brilliancies that were later anthologized in opening manuals.
- Mikhail Tal experimented with the Bongcloud-precursor 2. Ke2!? in simultaneous exhibitions, delighting crowds and baffling opponents.
- Grandmaster Bent Larsen revived 1. b3 in the 1960s, scoring notable wins against World Championship candidates.
- More recently, Magnus Carlsen has sporadically deployed odd first moves (1. g3, 1. a4) to sidestep expert preparation at elite level.
Illustrative Examples
The list below shows a spectrum of uncommon openings with typical move orders:
- Anderssen’s Opening: 1. a3
- Bird’s Opening: 1. f4 (still rare at top level)
- Barnes Defense: 1. e4 f6
- Polish (Orangutan) Opening: 1. b4
- St. George Defense: 1. e4 a6
- King’s Fianchetto Opening: 1. g3
- Englund Gambit: 1. d4 e5?!
Miniature Example – Groan Attack (1. g4)

Famous Encounters
One of the best-known successes with an uncommon opening is Larsen–Spassky, Belgrade 1970. Larsen, playing 1. b3, outplayed the reigning World Champion candidate Boris Spassky in 30 moves, demonstrating that off-beat openings can lead to rich, strategic battles instead of immediate refutation.
Common Pitfalls
- Objective inferiority: Some rare openings are rare because they concede a long-term positional weakness (e.g., 1. e4 f6 exposes the king and stunts development).
- Lack of theory as a double-edged sword: While your opponent may be unsure, you, too, must navigate new terrain without established roadmaps.
- Over-reliance on surprise: At higher levels, once an uncommon opening is “solved” or thoroughly prepared against, its practical value can plummet.
Interesting Facts & Anecdotes
- The nickname “Orangutan Opening” for 1. b4 originates from Savielly Tartakower’s visit to the Bronx Zoo in 1924. According to legend, he asked the orangutan “Susan” for opening advice before playing 1. b4 against Geza Maróczy the next day—and won.
- The Bongcloud Attack (1. e4 e5 2. Ke2) was long considered a joke until both Hikaru Nakamura and Magnus Carlsen used it in high-profile games on Chess.com during the 2021 Meltwater Champions Tour.
- Uncommon openings feature heavily in Chess960, where the starting position varies, making every “opening” technically uncommon.
Practical Tips
- Study model games: Even if theory is thin, a handful of high-quality annotated games can provide thematic ideas.
- Understand transpositions: Some unusual first moves can transpose to mainstream systems (e.g., 1. Nf3 d5 2. g3 can reach King’s Indian Attack structures).
- Keep flexibility: Choose lines that allow you to bail out into more orthodox setups if the surprise fails.
- Beware of traps—both for and against you: Because theory gaps are wider, tactical tricks abound.
