Polish Opening: Czech Defense
Polish Opening (1. b4)
Definition
The Polish Opening – sometimes called the Orangutan or, in older sources, the Sokolsky Opening – begins with the flank move 1. b4. White immediately seizes space on the queenside and prepares to fianchetto the queen’s-bishop to b2, pointing it menacingly along the long a1–h8 diagonal.
How It Is Used in Chess
- Surprise weapon: Because it is off the beaten path, the Polish often catches opponents who are overly booked-up in 1. e4 and 1. d4 systems by surprise.
- Flexible transpositions: After 1…e6 or 1…d5, the game can transpose into an English-type structure; after 1…Nf6 or 1…g6 it can resemble a reversed Grünfeld.
- Practical choice in rapid/blitz: Its strategic ideas are easy to grasp, making it popular in faster time controls where concrete home preparation matters less.
Strategic Themes
- Queenside space: The pawn on b4 supports an eventual b4–b5 advance to harass Black’s queenside and gain more territory.
- Dark-square pressure: Bb2 targets the central e5-square; if Black ever plays …e5, the bishop becomes a powerful piece.
- Central break with e4: After g3, Bg2, and Nf3, White can prepare e2-e4 to strike in the centre, relying on the bishop on b2 as support.
- Structural risk: The b-pawn can become over-extended; if Black provokes c6–c5 or a timely …a5, the pawn can be undermined.
Historical Significance
The opening owes much of its fame to Grandmaster Savielly Tartakower, who reputedly “named it on the spot” after debating opening strategy with other masters while visiting a zoo in New York in 1924. Tartakower immediately employed 1. b4 against then-world-champion José Raúl Capablanca the very next day. Although Tartakower lost, the audacity of the idea left a lasting impression, and the name “Orangutan” stuck. Polish players such as Karel Opočenský and Vladimír Vuković later analysed the opening in depth, giving rise to the modern name “Polish Opening.”

Despite losing, Tartakower demonstrated many of the strategic themes: central e5 pressure, a fianchettoed bishop, and rapid queenside expansion.
Popular Variations
- 1…e5 2.Bb2: Black grabs central space. After 2…Bxb4 3.Bxe5 Nf6 4.Nf3, the position is roughly equal but highly unbalanced.
- 1…d5 2.Bb2: A symmetrical setup often leading to reversed Queen’s Gambit lines.
- Bicego Gambit (1…c5 2.bxc5 e5): A speculative pawn sacrifice by Black for rapid development.
Interesting Facts & Anecdotes
- Grandmaster Boris Spassky used 1. b4 to beat David Bronstein at Leningrad 1960, giving the opening its first elite-level success.
- The nickname “Orangutan” originated from New York’s Bronx Zoo, where Tartakower allegedly asked an orangutan named Susan to pick his opening move by climbing on a board.
- The ECO code for the Polish Opening family is A00, lumping it among “irregular” openings despite its rich theory today.
Czech Defense
Definition
The term Czech Defense most commonly refers to the solid line of the Pirc Defense characterised by an early …c6:
Main move-order: 1. e4 d6 2. d4 Nf6 3. Nc3 c6.
Occasionally, Czech Defense is also used for the Caro-Kann line 1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6, so you may encounter the name in both contexts. Both share the same spirit: extreme solidity, a robust central pawn chain, and a deliberate counter-punching philosophy typical of Czech grandmasters of the mid-20th century (notably Luděk Pachman and Vlastimil Hort).
How It Is Used in Chess
- Safety first: By placing a pawn on c6, Black blunts ideas of an early e5 fork and keeps the b5-square guarded, preparing …e5 under favourable circumstances.
- Flexible transpositions: The structure can morph into a Czech Benoni with …e5, or into a restrained Philidor-type setup with …Nbd7, …Qc7, and …e5.
- Counter-attack plan: Black often waits for White to over-extend in the centre, then hits back with breaks such as …e5 or …c5.
Strategic & Tactical Themes
- Dark-square strategy: Black’s pawns on d6 and e5 (or e6) create a dark-square fortress around d6–e5–f6.
- Light-squared bishop dilemma: The c8-bishop can be passive; plans like …b5–…Bb7 or …Qa5, …b5, and …Bb7 aim to activate it.
- Delayed king-side confrontation: White often pushes f2-f4, but Black’s flexible pieces can challenge the centre with well-timed …e5.
- Pawn breaks: …c5 (Benoni style) or …e5 (Philidor style) are the main dynamic resources.
Historical Background
The variation gained prominence in the 1950s and 1960s among Czech and Slovak masters looking for an alternative to the then-fashionable King’s Indian. Its most celebrated adherent was Grandmaster Luděk Pachman, who wrote extensively about its positional virtues. In modern times, elite players such as Vassily Ivanchuk and Alexander Morozevich have employed the Czech Defense to surprise theoretically-armed opponents.
Illustrative Example
Ivanchuk – Morozevich, Linares 2004 (simplified):
Black’s …Qa5 both pins and prepares …e5, illustrating the latent tactical power of the setup.
Typical Move-Order Tricks
- Delayed …c6: 1. e4 d6 2. d4 Nf6 3. Nc3 g6. Black keeps options open; only after 4. f4 may he play …c6 to transpose back.
- Caro-Kann Czech: 1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ exf6. Black accepts structural weaknesses (isolated doubled pawns) in exchange for the bishop pair and control of e5.
Interesting Facts & Anecdotes
- The line 1. e4 d6 2. d4 Nf6 3. Nc3 c6 was a mainstay of Czech national team preparations during the 1960s Olympiads, prompting Western analysts to dub it the Czech Pirc.
- Bobby Fischer analysed the Caro-Kann Czech Defense (4…Nf6) in My 60 Memorable Games, calling it “the most resilient line” because it is so hard to break.
- Because of its ultra-solid nature, computer engines often give a small but stable plus for White, yet practical results at master level hover around 50 %, attesting to its reliability.
