Sokolsky Opening (1. b4)
Sokolsky Opening (1. b4) – also known as the Orangutan or Polish Opening
Definition
The Sokolsky Opening is a flank opening that begins with the pawn move 1. b4. By immediately advancing the b-pawn two squares, White seeks rapid queenside space, the fianchetto of the bishop to b2, and unusual, asymmetrical positions that can take an unprepared opponent out of familiar territory. The opening is named after the Ukrainian–Belarusian master Alexey Pavlovich Sokolsky (1908-1969), whose analyses in the mid-20th century gave the line serious theoretical footing.
Typical Move Order
- Main tabiya: 1. b4 d5 2. Bb2
- Classical Counter: 1. b4 e5 2. Bb2 Bxb4
- English Hybrid: 1. b4 Nf6 2. Bb2 g6 3. e3 Bg7
Most branches revolve around whether Black captures the b-pawn and how White recoups or sacrifices it for activity.
Strategic Ideas
- Queenside Space and Pressure – The b-pawn aims to seize squares a5 and c5 and prepare the rook lift to b3 or b5 in some lines.
- Bb2 Fianchetto – Placing the bishop on the long diagonal (a1–h8) can target e5, g7, and sometimes c6, influencing the center from afar.
- Unbalanced Pawn Structure – If Black accepts the pawn (…Bxb4 or …Qxb4), White often gains a lead in development and open lines for compensation.
- Delayed Center – White usually postpones central pawn advances (c2-c4 or e2-e3/e4) until piece activity justifies them, mirroring ideas from the English and Réti systems.
- Psychological Weapon – Because it appears “off-beat,” the Sokolsky frequently serves as a surprise choice, especially in rapid or blitz play.
Historical Background
While the move 1. b4 had been tried sporadically in the 19th century, it was Savielly Tartakower who popularized it at top level. After using the line against reigning World Champion José Raúl Capablanca at New York 1924, Tartakower reportedly christened it the “Orangutan” because he had visited the Bronx Zoo earlier that day! Sokolsky, however, produced the first comprehensive monograph on 1. b4 (published 1963), leading Soviet sources to attach his name to the opening.
Occasional outings by grandmasters such as Vasily Smyslov, Boris Spassky, and Hikaru Nakamura have kept the opening in theoreticians’ notebooks, though it remains a sideline at elite classical level.

Contemporary Usage
- Rapid & Blitz Choice: Owing to its surprise value, 1. b4 scores respectably in faster time controls.
- Correspondence & Engine Tests: Modern engines such as Stockfish and Leela evaluate 1. b4 near equality, proving that the move is objectively sound even if not theoretically critical.
- Club Level Appeal: The resulting positions differ drastically from mainstream openings, granting practical chances against memorized repertoire players.
Typical Plans for Both Sides
White’s Plans:
- Rapidly deploy Bb2, Nf3, e3, c4, Qa4 (to pin c6 or a4), and sometimes a2-a3 to undermine a captured bishop on b4.
- If Black delays …d5, strike with 2. e4 (the Sokolsky Gambit) aiming for central domination.
- A rook lift via Rb1–b3–g3 becomes dangerous against kingside fianchettos.
Black’s Plans:
- Accept the pawn and challenge White to prove compensation; solidify with …d6, …Be7, and …O-O.
- Refuse the pawn with …d5 or …Nf6, building a classical center and exploiting the slightly weakened c3-square.
- Counter on the queenside with …a5, restraining b4-b5, or strike in the center with …c5 breaks.
Interesting Facts & Anecdotes
- The name “Orangutan” may also reference the opening’s “long arms” (pawns and bishops) stretching across the board.
- When asked why he played 1. b4 against Capablanca, Tartakower quipped, “Why not? Capablanca is a very strong player; I must confuse him!”
- In 2015 GM Richard Rapport used the Sokolsky to defeat GM Andrei Volokitin in the European Team Championship, sparking a brief revival among young grandmasters.
- Because the initial move does not contest the center directly, some databases classify 1. b4 games under the A00 code—miscellaneous irregular openings.
Conclusion
The Sokolsky Opening epitomizes creative, flank-oriented chess. While seldom the main weapon of World Champions, it remains a viable surprise system rich in strategic and tactical themes. Players willing to embrace unorthodox structures and memorize a few key motifs can add a potent arrow to their opening quiver with 1. b4.
