Maróczy Bind
In chess, the Maróczy Bind () is a term alternately used to refer to an opening or its associated pawn structure, named for the Hungarian grandmaster Géza Maróczy. When the Bind is discussed as an opening, it is defined as 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 g6 5. c4. The Maróczy Bind opening is a continuation of the Sicilian Defence, Accelerated Dragon, where 5. c4 is the characteristic move. When the Maróczy Bind is discussed as a pawn structure, attention is paid to both sides' strategic plans, as required by the placement of the  pawns. Chess writers also note the possibility for the same or similar pawn structure to arise by transposition, especially via the English opening or the King's Indian Defense. In the Maróczy pawn structure, White's c- and e-pawns control the d5-square, making it difficult for Black to open their position with ...d5. Black often settles for the less active ...d6 instead, and may develop a Hedgehog pawn formation against the Bind. History. The first game known to feature what would later be known as the Maróczy Bind was Swiderski–Maróczy, Monte Carlo 1904. Oddly, Maróczy never played  it as White. However, the 1906 March–April issue of the "Wiener Schachzeitung" reproduced from "Magyar Sakklap" Maróczy's annotations to the game Tarrasch–Marshall, Nuremberg (match) 1905 (which began 1.e4 c5 2.d4 cxd4 3.Nf3 a6 4.Nxd4 g6 5.Be2 Bg7 6.Nc3 Nc6). "On four consecutive moves (moves 3–6) Maróczy stressed the value of the move c4." For several decades, it was generally considered tantamount to a blunder for Black to allow the Maróczy Bind. For example, Harry Golombek, in "Capablanca's 100 Best Games of Chess" (1947), gave a to Black's fourth move in the line 1.e4 c5 2.Ne2  d6 3.d4 cxd4 4.Nxd4 g6, a form of the Accelerated Dragon variation of the Sicilian Defence, stating that 4...Nf6 was "necessary" to make White block his with 5.Nc3 and thus avoid the Bind. Golombek gave an to 5.c4, establishing the Bind, explaining: "This strong move gives White control of the centre and Black must grovel about to find a counter-attack." Reuben Fine, writing in 1948, also considered the Bind very strong for White. Beginning in the 1950s, the Maróczy Bind became less feared as new methods were found for Black to combat it. The ninth edition of "Modern  Chess Openings" (1957) stated that Black had "worked loose" from the strictures of the Bind. Larry Evans wrote in the tenth edition (1965) that in response to the Accelerated Dragon, the Maróczy Bind "was once considered a refutation but now has lost much of its punch. White retains an advantage in space but Black's position is fundamentally sound." That remains the prevailing view, but some recent writers still emphasize that Black must find active or else be "strangled". However, John Nunn and Joe Gallagher observe: Although the Maroczy Bind is slightly passive for Black, players such as Larsen, Petursson  and Velimirović have shown that by patiently waiting for a lapse of concentration from White this line can offer winning chances for Black. The theoretical opinion is that White should maintain a slight advantage, but no one should believe that this is a line in which White cannot lose. Common opening lines.
