Polish Opening & King's Indian Defense
Polish Opening (a.k.a. Sokolsky Opening) – 1. b4
Definition
The Polish Opening is a flank opening for White that begins with the move 1. b4. By advancing the b-pawn two squares, White immediately contests the long dark-squared diagonal a1–h8 while postponing central occupation. The opening is also called the Sokolsky Opening (after the Ukrainian master Alexey Sokolsky) and sometimes the Orangutan (from a Zoo anecdote involving Savielly Tartakower).
Typical Move Orders & Main Ideas
The purest form is simply 1. b4, but common transpositions include:
- 1. b4 e5 2. Bb2 Bxb4 3. Bxe5 – the so-called Nimzowitsch Gambit.
- 1. b4 d5 2. Bb2 Nf6 3. e3 – aiming for a Reverse Slav structure.
- 1. b4 c6 2. Bb2 d5 3. Nf3 – heading toward a Caro-Kann-style center.
Strategic Themes
- Diagonal Pressure: The bishop on b2 eyes the crucial e5 and h8 squares, which can become tactical hotspots if Black castles kingside.
- Flexible Center: White often delays committing the central pawns, choosing between c2–c4, d2–d4, or e2–e4 depending on Black’s setup.
- Queenside Space: The advance b4–b5 can gain space, harass a knight on c6, or prepare Ba3 to exchange dark-squared bishops.
- Risk–Reward Balance: White spends a tempo on a wing pawn instead of central development; if Black seizes the center efficiently, the Polish can backfire.
Historical Notes
The nickname “Orangutan” stems from the 1924 New York tournament: Tartakower supposedly visited the Bronx Zoo, consulted an orangutan named Susan, and was “advised” to play 1. b4 against Maroczy, which he did—and won.
Usage in Modern Play
While rare at elite level, the opening is a respected surprise weapon:
- Fischer–Spassky, World Championship 1972 (Game 3): Fischer used 1. c4 and quickly transitioned into a Polish-like structure with b4, scoring his historic first classical win over Spassky.
- Grandmasters such as Richard Rapport, Baadur Jobava, and Hikaru Nakamura have occasionally employed 1. b4 in rapid or blitz to sidestep heavy preparation.

Interesting Facts
- According to database statistics, 1. b4 scores roughly the same as 1. a3 or 1. h3 at master level—surprisingly resilient for an offbeat debut.
- The move order 1. b4 c5 2. bxc5 e5 is occasionally dubbed the Polish Gambit Accepted for Black.
- Sokolsky wrote an entire monograph titled “The Opening 1. b2–b4” in 1963, an early single-move opening book.
King’s Indian Defense – 1. d4 Nf6 2. c4 g6 3. Nc3 Bg7
Definition
The King’s Indian Defense (KID) is a hypermodern response to 1. d4 in which Black permits White to occupy the center with pawns, intending to strike back later with …e5 or …c5. The classical starting position arises after:
1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6
Strategic Themes
- Delayed Counter-Center: Black often meets White’s space advantage with …e7–e5 or …c7–c5, undermining the d4-e4 duo.
- King-side Attack: In the Main Line (the Mar del Plata), Black castles short, plays …Nf6–d7, …f7–f5, and hurls pawns and pieces toward White’s king.
- Minor-Piece Imbalances: The dark-squared bishop on g7 is the soul of Black’s position; White usually retains the light-squared bishop to contest the long diagonal.
- Dynamic Rather Than Static: Structural weaknesses (e.g., d6-pawn, cramped queenside) are accepted in exchange for piece activity and attacking chances.
Main Variations
- Classical (Mar del Plata): 5. Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 – razor-sharp king-side race.
- Sämisch: 5. f3 – White builds a massive center; Black counters with …c5 or …e5, occasionally sacrificing material.
- Fianchetto: 3. g3 – positions become more positional; Black tries …c5 or …e5 breaks while avoiding early exchanges.
- Averbakh: 5. Be2 – early Bg5 ideas aim to neutralize the g7-bishop.
- Four Pawns Attack: 5. f4 – ultra-aggressive; leads to chaotic play after …c5 or …e5 breaks.
Historical Significance
The KID rose to prominence in the mid-20th century thanks to grandmasters like Isaac Boleslavsky and David Bronstein. Later, Bobby Fischer and Garry Kasparov made it a mainstay of world-championship practice, proving its soundness at the highest level. In the computer era it remains viable, with engines showing flexible ways to handle White’s space.
Illustrative Game
Kasparov vs. Kramnik, Dos Hermanas 1996 – a textbook Classical line where Kasparov’s queenside push met Kramnik’s timely pawn storm.
This encounter demonstrates both sides’ thematic pawn storms: White on the queenside with b4–b5, Black on the kingside with …f5–f4.
Modern Usage & Statistics
- According to recent master databases, the KID is played in roughly 7–9 % of games after 1. d4, making it the third most popular reply behind the Queen’s Gambit Declined and Nimzo-Indian complexes.
- Top proponents today include Teimour Radjabov, Alireza Firouzja, and gmnjdiaz (imaginary blitz specialist).
- White’s overall score is just slightly above 55 %, indicating a dynamically balanced opening.
Interesting Facts
- In the 1953 Candidates Tournament, Bronstein famously predicted the KID would become “the opening of the future”—a prophecy arguably fulfilled in the computer age.
- The line 5. h3, once considered toothless, has been revitalized by engine prep and is colloquially called the “Makogonov System.”
- Deep Blue’s team programmed specialized KID knowledge during its 1997 match versus Kasparov, though the opening never appeared in the six-game contest.
