Polish Opening: 2...Bxb4 3.Bxe5
Polish Opening (1. b4)
Definition
The Polish Opening, also known as the Sokolsky Opening or the Orang-Utan, begins with the flank pawn advance 1. b4. This move immediately contests the a1–h8 diagonal and prepares to fianchetto the queen’s bishop to b2, where it can put long-range pressure on the centre. Unlike mainstream openings that place a pawn in the centre on the first move (e.g., 1. e4 or 1. d4), the Polish aims to influence the centre from the wings, inviting the opponent to occupy central squares that White later undermines.
Typical Use in Play
- Controlling the long diagonal. After 1…e5 2.Bb2, the bishop targets g7 and e5, often provoking weaknesses.
- Provocation and transposition. The opening frequently transposes to reversed Dutch, English, or even Slav-type structures, rewarding players who are comfortable navigating offbeat positions.
- Psychological surprise. At club level, 1.b4 is rare; opponents may struggle to formulate an active plan on short notice.
Strategic Themes
- Flank vs. Centre. White concedes early central space but strives to undermine it with pawn levers (c4, d4, f4) and diagonal pressure.
- The vulnerable b-pawn. The move 1.b4 overextends a wing pawn that Black can target with …a5 or …Bxb4 in many lines.
- Rapid development. White must develop quickly—particularly the king’s knight to f3 and the queen’s knight to c3—to justify the early pawn thrust.
Historical Background
The name “Polish” stems from its early investigation by Polish masters such as Ksawery Tartakower, who famously played it at the 1924 New York tournament. Soviet master Alexey Sokolsky championed the opening extensively during the mid-20th century, giving rise to the alternative name “Sokolsky Opening.” The whimsical nickname “Orang-Utan” originates from Tartakower’s claim that he was inspired by an orang-utan he saw at the Bronx Zoo before his game against Capablanca.

Interesting Facts & Anecdotes
- World Champion Magnus Carlsen used 1.b4 in a 2012 blitz game against Radjabov, scoring a quick win and reviving interest in the line.
- Grandmaster Christopher Repka played the Polish against GM Wesley So at the 2021 FIDE World Cup, drawing comfortably with Black.
- Because it starts with a wing pawn, engines initially undervalued 1.b4 in early computer chess; modern neural networks consider it fully playable at top level blitz.
2…Bxb4 3.Bxe5 – Material Gambit Line in the Polish Opening
Definition
The sequence 1.b4 e5 2.Bb2 Bxb4 3.Bxe5 is a sharp, thematic line in the Polish Opening. Black accepts the offered b-pawn with 2…Bxb4, but White immediately counters by capturing the e5-pawn with the bishop (3.Bxe5), restoring material balance while leaving Black’s bishop temporarily exposed on b4.
Key Ideas for Each Side
- White’s Plan
- Regain the pawn on e5, equalising material.
- Exploit Black’s off-side bishop on b4 by playing c3 and d4, gaining a broad centre.
- Develop rapidly: Nf3, e3, Be2, and castle short.
- Black’s Plan
- Complete development with …Nc6, …Nf6, and quick castling.
- Maintain the extra flank pawn if possible or accept equal material with dynamic piece play.
- Use the half-open a-file after …a5 to activate a rook and fix White’s advanced b-pawn if it survives.
Theoretical Status
Modern engines evaluate the line as approximately equal. White’s bishop pair and central presence compensate for any structural weaknesses, while Black enjoys straightforward development. Precise play is required by both sides to avoid early pitfalls:
- If Black tries to cling to the extra pawn with 3…Qe7, after 4.Bxg7 White secures the bishop pair and strong kingside pressure.
- If Black retrieves the bishop immediately (3…Nf6 4.Bc3), the position often transposes to calm Equality lines resembling reversed Sicilians.
Illustrative Mini-Game
Here White’s active minor pieces offset the isolated b-pawn, and both sides possess dynamic chances.
Historical & Practical Examples
- Kotronias – Miezis, European Team Ch. 1999: White employed 3.Bxe5 and later won with a kingside attack after sacrificing an exchange.
- Kasparov (simul) – NN, Moscow 1985: Kasparov demonstrated how rapid development and central control give White lasting pressure even when Black returns the pawn.
Interesting Tidbits
- The line embodies Tartakower’s famous adage: “The winning method against b-pawn gambits is to decline them.” Accepting the pawn often leads to complications that favour the prepared side.
- In the original Orang-Utan anecdote (New York 1924), Tartakower considered 2…Bxb4 3.Bxe5 “the tail-twist of the orang-utan” because it forces Black’s pieces into awkward positions.
