Vasja Pirc

Vasja Pirc (/ˈʋâːsja ˈpîːrt͡s/) (December 19, 1907 – June 2, 1980) was a leading Yugoslav (Slovenian) chess player. His name is most familiar to contemporary players as the originator of the hypermodern Pirc Defense.

Pirc was champion of Yugoslavia five times: 1935, 1936, 1937, 1951, and 1953. He was awarded the International Master (IM) title in 1950, and the Grandmaster (GM) title in 1953. He was made an International Arbiter in 1973.

Pirc was born in Idrija, then a part of the Austrian-Hungarian Empire, and died in Ljubljana.

Pirc Defence

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.

General remarks

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.

Modern Defense

The Modern Defense (also known as the Robatsch Defence after Karl Robatsch) is a hypermodern chess opening in which Black allows White to occupy the center with pawns on d4 and e4, then proceeds to attack and undermine this "ideal" center without attempting to occupy it themselves. The opening has been most notably used by British grandmasters Nigel Davies and Colin McNab.

The Modern Defense is closely related to the Pirc Defence, the primary difference being that in the Modern, Black delays developing his knight to f6. (The delay of ...Nf6 attacking White's pawn on e4 gives White the option of blunting the g7-bishop with c2–c3.) Transpositional possibilities between the two openings are rife.

The Encyclopaedia of Chess Openings (ECO) classifies the Modern Defense as code B06, while codes B07 to B09 are assigned to the Pirc. The tenth edition of Modern Chess Openings (1965) grouped the Pirc and Robatsch together as the "Pirc–Robatsch Defense".

Main lines

A typical move order for the Modern Defense is 1. e4 g6 2. d4 Bg7, with main lines:

Chess

Chess is a two-player board game played on a chessboard, a checkered gameboard with 64 squares arranged in an eight-by-eight grid. Chess is played by millions of people worldwide, both amateurs and professionals.

Each player begins the game with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. Each of the six piece types moves differently. The most powerful piece is the queen and the least powerful piece is the pawn. The objective is to 'checkmate' the opponent's king by placing it under an inescapable threat of capture. To this end, a player's pieces are used to attack and capture the opponent's pieces, while supporting their own. In addition to checkmate, the game can be won by voluntary resignation by the opponent, which typically occurs when too much material is lost, or if checkmate appears unavoidable. A game may also result in a draw in several ways.

Chess is believed to have originated in India, some time before the 7th century; the Indian game of chaturanga is also the likely ancestor of xiangqi and shogi. The pieces took on their current powers in Spain in the late 15th century; the rules were finally standardized in the 19th century.

Chess opening

A chess opening is the group of initial moves of a chess game. Recognized sequences of initial moves are referred to as openings by White, or defenses by Black, but opening is also used as the general term. There are many dozens of different openings, and hundreds of named variants. The Oxford Companion to Chess lists 1,327 named openings and variants. These vary widely in character from quiet positional play to wild tactical play. In addition to referring to specific move sequences, the opening is the first phase of a chess game, the other phases being the middlegame and the endgame.

A sequence of opening moves that is considered standard (often catalogued in a reference work such as the Encyclopaedia of Chess Openings) is referred to as "the book moves", or simply "book". These reference works often present these move sequences in simple algebraic notation, opening trees, or theory tables. When a game begins to deviate from known opening theory, the players are said to be "out of book". In some opening lines, the moves considered best for both sides have been worked out for twenty to twenty-five moves or more. Some analysis goes to thirty or thirty-five moves, as in the classical King's Indian Defense and in the Sveshnikov and Najdorf variations of the Sicilian Defense. Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller there since games are rarely decided in the opening. The study of openings can become unbalanced if it is to the exclusion of tactical training and middlegame and endgame strategy.
