Indian Openings

Hen a Catalan nobleman, Count Ermengol of Urgell, bequeathed his chess pieces to the Convent of St. Giles near N mes, France, he _ could little have anticipated that he was also making a bequest to chess itself. The count's will, which can be dated to around A.D. 1008, is the earliest European source to mention chess, and the game thus makes its appearance in western civilization in Catalonia. Nearly a millennium later, in 1981, the chess players of La Seu d'Urgell, a small town in the Catalan...

Here are two strategic ideas behind 2 . . . c6. The first is to bolster the center without hemming in Black's problem child of the Queen's Gambit Declined the light-squared bishop. The second is to be able to support the advance . . . b5 after a later . . . dxc4. This would either guard the pawn on c4 or attack the piece that has captured it, winning a tempo for queenside expansion. The Slav Semi-Slav is a relatively recent addition to Black's queen pawn defenses. It was originated by Alapin a...

The Classical Variation, 3 Nc3 Bg7 4 e4 d6 5 Nf3 0-0 6 Be2 cols. 1-42, see above diagram , has managed through the waxing and waning of its viability to accumulate a massive pedigree, culminating in its current feverish popularity. The main line, 6 e5 7 0-0 Nc6 8 d5 Ne7 9 Nel cols. 1-6 , still leads combatants to move 25 and beyond before novelties are sprung. The zenith of fashion for the last couple years is the Bayonet Attack, 9 b4, when Kramnik's taciturn answer to 9 . . . Nh5, 10 Rel cols....

He King's Gambit is part of the mythology of chess. For more than a hundred years this opening has represented a lost golden age, a nobler past of swashbucking sacrifice and gung-ho attack, when few players were unsporting enough to defend correctly. Golden ages have a tendency to evaporate on scrutiny, and the romanticized heyday of the King's Gambit is no exception. But the unro-mantic fact that the opening's successes were very often due to bad technique is of historical interest. The...
