The Pirc Defence (correctly pronounced "peerts", but often mispronounced "perk"), sometimes known as the Ufimtsev Defence or Yugoslav Defence, is a chess opening characterised by Black responding to 1.e4 with 1...d6 and 2...Nf6, followed by ...g6 and ...Bg7, while allowing White to establish an impressive-looking centre with pawns on d4 and e4. It is named after the Slovenian Grandmaster Vasja Pirc.
The Pirc Defence is a relatively new opening; while it was seen on occasion in the late nineteenth century, it was considered irregular, thus remaining a sideline. The opening began gaining some popularity only after World War II, and by the 1960s it was regarded as playable, owing in large part to the efforts of Canadian Grandmaster Duncan Suttles. Black, in hypermodern fashion, does not immediately stake a claim in the centre with pawns; rather, Black works to undermine White's centre from the flanks. Its first appearance in a World Championship match was in 1972, when it was played by Bobby Fischer against Boris Spassky at Reykjavík (game 17); the game ended in a draw.
Pirc Defence normally refers to the opening moves 1. 2. 3. . This is the most commonly played line after Black responds to 1.e4 with 1...d6. It has been claimed to give rise to somewhat interesting and exciting games, where Black will have counterplay but has to be cautious about playing too passively. According to Garry Kasparov, the Pirc Defence is "hardly worth using in the tournaments of the highest category", as it gives White "too many opportunities for anybody's liking".
A distinction is usually drawn between the Pirc and lines where Black delays the development of his knight to f6, or omits it altogether; this is known as the Modern or Robatsch Defence. The tenth edition of Modern Chess Openings (1965) grouped the Pirc and Robatsch together as the "Pirc–Robatsch Defense".
