The Orangutan Opening, also known as the Sokolsky Opening or the Polish Opening, is an unconventional chess opening that begins with the move 1.b4. Although it is not common at top level, it has occasionally been used by grandmasters to surprise their opponents. Its name is attributed to Grandmaster Savielly Tartakower, who, during the New York tournament in 1924, decided to play this opening after a visit to the zoo, where an orangutan named Susan “inspired” the move.
Although it is a flank opening and less orthodox than 1.e4 or 1.d4, it can lead to dynamic, unbalanced positions that may unsettle unprepared players.
Objectives of the Orangutan Opening
By choosing the Orangutan Opening, White pursues several strategic goals:
- Queenside influence: By advancing the pawn to b4, White aims to influence the c5 and a5 squares, limiting Black’s options on the queenside.
- Development of the queen’s bishop: The move 1.b4 facilitates a fianchetto of the bishop to b2, from where it can control the a1–h8 diagonal and exert pressure on the center and the opponent’s kingside.
- Disrupting the opponent: By opting for a less common opening, White tries to take the opponent out of their theoretical preparation and steer the game into less explored territory.
Variations of the Orangutan Opening
1. Main Line
In this line, Black responds with 1…e5, aiming to occupy the center and challenge White’s pawn advance. Typical play continues with 2.Bb2 Bxb4 3.Bxe5 Nf6 4.Nf3 Nc6 5.Bb2 d5, where Black tries to exploit their central control and active development.
2. The 1…d5 Variation

3. The 1…c6 Variation
With 1…c6, Black prepares …d5 and adopts a solid approach. White can continue with 2.Bb2 d5 3.e3 Nf6 4.c4, trying to strike in the center and make use of the bishop’s placement on b2.
4. The 1…f5 Variation
This response is less common and aims for aggressive play by Black. After 1…f5, White can reply with 2.Bb2 Nf6 3.e3 e6 4.a3, preparing c4 and seeking to counter Black’s expansion on the kingside.
Comparison of the main variations
| Variation | Advantages | Disadvantages |
|---|---|---|
| Main Line (1…e5) | Directly challenges the b4 pawn and aims for central control. | Can lead to open positions that may favor White if Black is not precise. |
| 1…d5 Variation | Establishes immediate central presence and natural development. | The bishop on b2 can become very strong on the a1–h8 diagonal. |
| 1…c6 Variation | Prepares …d5 and keeps a solid structure. | Can become passive if Black does not seek active counterplay. |
| 1…f5 Variation | Aims for aggressive, unbalanced play. | Weakens the kingside and can be risky if White responds accurately. |
