Shams Khan does lose sometimes but such games are never miniatures!

1. e4 e6 2. d4 d5 The French defence was analyzed by Lucena in the 15th century but was aptly named after players from Paris adopted it in the 1834 correspondence game against London. Except Bobby Fischer, who stumbled against it quite often with White in his meteoric career, every other World champion has played it. Botvinnik used it as a strong attacking weapon with the Winawer variation. 3. Nd2 The Tarrasch line avoiding the Winawer with 3.Nc3 Bb4 3... c5 4. exd5 exd5 5. Bb5+ Nc6 6. Ngf3 Nf6 7.

Ruy Lopez (Spanish Opening). This opening is half a millennium old and represents the classic play in a game of chess with 'e4' opening. The earliest reference is in the historic Gottingen manuscript of 1490. The Spanish priest, Ruy Lopez, in his Libro del Ajedrez was the first to analyse this variation systematically in 1561, so this opening still bears his name.

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 It has become customary to play 3...a6 the Paul Morphy variation in Grandmaster chess. Though it appears irregular at first glance, even 150 years later, Morphy's line is considered the best defence against the Ruy Lopez. 4. Ba4 Nf6 5. O-O Nxe4 Open variation is a major branch of Ruy Lopez. Though logical, it needs guts to take the unprotected pawn. The idea is that while White takes time to recapture the pawn, Black can stake claim in the centre. In recent times, Korchnoi has been a major champion of this line. 6. d4 b5 7.

Mandviwala plays originally to get a winning advantage against the top seeded AICCF player only to fritter away the advantage due to a few weak moves.

1. d4 Nf6 2. c4 g6 King's Indian defence. It was developed by 'hypermodernists' in 1920s but was little appreciated until Bronstein and Boleslavsky scored brilliant victories with it in 1940s. This defense was also a Fischer favourite apart from Grunfeld defence. Though, Black allows White to consolidate his central pawn mass, he must make a timely break with ...e5 or .. . c5.
