Commentary

The move ‘1.b4’ is also know as the Orangutan or the Sokolsky Opening. The name Polish Opening comes from it’s similarity to the Polish Defense (“1.d4 b5”). Alexei Pavlovich Sokolsky wrote a monograph on this opening entitled Debyut 1 b2-b4 in 1963 which led to his name being included as a name for this opening. Perhaps the most curious name for this strange opening is “the Orangutan.” Savielly Tartakower wrote in his book My Best Games, “This move, which has so bizarre an aspect, occupies a place of honour amongst the `freak' openings. Later, at the New York Tournament of 1924, I termed this the `Orangutang' Opening, not only because I employed it there against Maroczy -- after a previous consultation with a young orangutan (during a visit by all the masters to the New York Zoo on the eve of the game in question) but also since the climbing movement of the pawn to b4 and then b5 is reminiscent of that inventive animal. The name has stuck." Before the 1924 game against Maroczy, Tartakower had played the opening against Richard Réti, and Arpad Vajda. He employed the Orangutan against Edgar Colle two years later in 1926. Before Tartakower’s use of the opening, Nikolai Vasilyevich Bugayev(1837-1903) published analysis of the opening in Shakhmatnoye Obozreniye around the turn of the century.
