Grob Attack
Grob's Attack is an unconventional chess opening in which White begins with the move: :1. b:Chess Opening Theory/1. g4, g4 It is widely considered to be one of the worst possible first moves for White. International Master John L. Watson, John Watson writes, "As far as I can tell, 1 g4 is competitive with 1 h4 for the honour of being White's worst first move. Against an informed or skilled opponent, it is simply masochistic." History and usage The opening takes its name from Swiss International Master Henri Grob (1904–1974) who analysed it extensively and played hundreds of Correspondence chess, correspondence games with it. In Grob's newspaper column analysis of this opening, he referred to it as the Spike Opening, a name which is still used occasionally. Other early references used the name Ahlhausen's Opening, after Carl Ahlhausen (1835–1892) of Berlin, one of the first to play 1.g4.

Irregular Chess Openings
In chess, irregular opening is a traditional term for any opening considered unusual or unorthodox. In the early 19th century it was used for any opening not beginning with 1.e4 e5 (the Open Game) or 1.d4 d5 (the Closed Game). As opening theory has developed and openings formerly considered "irregular" have become standard, the term has been used less frequently.Hooper & Whyld, ''The Oxford Companion to Chess'', Oxford University Press, 1996, p 182, "Irregular opening, in the early 19th century any opening that did not begin with 1.e4 e5 or 1.d4 d5. However, Jaenisch said, 'As this distinction is purely arbitrary, and unfounded on principle, we cannot ourselves adopt it. We distinguish all the openings as "correct", or else as "incorrect" or "hazardous".' Since then many so-called irregular openings have become standard play. These and many other openings have acquired names and the term irregular opening has gradually fallen into disuse." Because these openings are not popular wi ...

Castling
Castling is a move in chess. It consists of moving the king two squares toward a rook on the same and then moving the rook to the square that the king passed over. Castling is permitted only if neither the king nor the rook has previously moved; the squares between the king and the rook are vacant; and the king does not leave, cross over, or finish on a square attacked by an enemy piece. Castling is the only move in chess in which two pieces are moved at once. Castling with the is called ''kingside castling'', and castling with the is called ''queenside castling''. In both algebraic and descriptive notations, castling kingside is written as 0-0 and castling queenside as 0-0-0. Castling originates from the ''king's leap'', a two-square king move added to European chess between the 14th and 15th centuries, and took on its present form in the 17th century. Local variations in castling rules were common, however, persisting in Italy until the late 19th century. Castling does not ...

Fianchetto
In chess, the fianchetto ( or ; "little flank") is a pattern of wherein a bishop is developed to the second rank of the adjacent b- or g-, the having been moved one or two squares forward. The fianchetto is a staple of many " hypermodern" openings, whose philosophy is to delay direct occupation of the with the plan of undermining and destroying the opponent's central outpost. It also regularly occurs in Indian defences. The fianchetto is less common in Open Games (1.e4 e5), but the is sometimes fianchettoed by Black in the Ruy Lopez or by White in an uncommon variation of the Vienna Game. One of the major benefits of the fianchetto is that it often allows the fianchettoed bishop to become more active. A fianchettoed position, however, also presents some opportunities for the opponent: if the fianchettoed bishop can be , the squares the bishop was formerly protecting will become weak (see ') and can form the basis of an attack (particularly if the fianchetto was performe ...
