Polish: 2...Bxb4 3.Bxe5 Nf6 (Polish Opening)
Polish: 2...Bxb4 3.Bxe5 Nf6
Definition
The phrase “Polish: 2…Bxb4 3.Bxe5 Nf6” refers to a specific move-sequence within the Polish Opening, which begins with 1.b4. After the standard reply 1…e5, White usually plays 2.Bb2, attacking the pawn on e5 from the long diagonal. Black’s most challenging response is 2…Bxb4, capturing the b-pawn with the queen’s bishop. White immediately regains material with 3.Bxe5, and Black develops with 3…Nf6, attacking the e4–square and preparing to castle.
How It Is Used in Chess
Players and writers cite the shorthand “2…Bxb4 3.Bxe5 Nf6” to identify the main theoretical branch of the Polish Opening after 1.b4 e5 2.Bb2. In databases it usually falls under ECO code A40 (or occasionally A00). The line is a practical example of material imbalance: both sides have given up a wing pawn for a central pawn, leading to open lines and asymmetrical pawn structures.
Strategic and Historical Significance
Strategically, the variation illustrates several concepts:
- Diagonals vs. central presence: White’s bishop on e5 occupies a central outpost, while Black’s bishop on b4 has pressured the knight’s natural square c3 and weakened White’s queenside.
- Initiative trade-off: By playing 3…Nf6, Black gives back material equality but gains rapid development and easy castling, whereas White spends time relocating the e5-bishop or protecting it.
- Long-term pawn weaknesses: The capture on b4 leaves White with a missing b-pawn, so the a- and c-pawns become potential targets in the endgame.
Historically, the move order became popular in correspondence play during the 1960s and 1970s, when players such as IM Jerzy Konikowski (Poland) tested the Polish Opening extensively against classical e-pawn systems. Modern computer engines confirm that Black can equalise after 3…Nf6, making this the critical battleground of the opening.
Typical Continuations
- 4.Nf3 (protecting the bishop) O-O 5.e3 d5, leading to an English-style structure.
- 4.e3 d5 5.Nf3 O-O 6.Be2, where both sides complete development with roughly equal chances.
- 4.c4 (ambitious but double-edged) O-O 5.Nc3 Re8, increasing central tension.

Interesting Facts & Anecdotes
- The name “Polish Opening” arose because Polish masters—most notably Savielly Tartakower—experimented with 1.b4 in pre-war cafés of Warsaw and Kraków.
- When Richard Réti first saw 1.b4 he reportedly quipped, “Now that’s an opening you can play only once in a lifetime.” Modern engines disagree, giving White respectable chances if well prepared.
- Grandmaster Baadur Jobava successfully used the exact line (2…Bxb4 3.Bxe5 Nf6) in rapid chess to surprise higher-rated opponents, showing its continued practical value.
