While the umpire (1) in shot stands at the bowler's end of the pitch, his colleague stands in the outfield, usually in or near the fielding position called "square leg", so that he is in line with the popping crease (7) at the striker's end of the pitch. The bowling crease (not numbered) is the one on which the wicket is located between the return creases (12). The bowler (4) intends to hit the wicket (9) with the ball (5) or, at least, to prevent the striker (8) from scoring runs. The striker (8) intends, by using his bat, to defend his wicket and, if possible, to hit the ball away from the pitch in order to score runs.

Cricket has close historical ties with Australian rules football and many players have competed at top levels in both sports.[136] In 1858, prominent Australian cricketer Tom Wills called for the formation of a "foot-ball club" with "a code of laws" to keep cricketers fit during the off-season. The Melbourne Football Club was founded the following year, and Wills and three other members codified the first laws of the game.[137] It is typically played on modified cricket fields.[138] 

The ICC also organises competitions that are for several countries at once, including the Cricket World Cup, ICC T20 World Cup and ICC Champions Trophy. A league competition for Test matches played as part of normal tours, the ICC World Test Championship, had been proposed several times, and its first instance began in 2019. A league competition for ODIs, the 2020–22 ICC Cricket World Cup Super League, is planned to begin in 2020. The ICC maintains Test rankings, ODI rankings and T20 rankings systems for the countries which play these forms of cricket.
Crickets are hemimetabolic insects, whose lifecycle consists of an egg stage, a larval or nymph stage that increasingly resembles the adult form as the nymph grows, and an adult stage. The egg hatches into a nymph about the size of a fruit fly. This passes through about 10 larval stages, and with each successive moult, it becomes more like an adult. After the final moult, the genitalia and wings are fully developed, but a period of maturation is needed before the cricket is ready to breed.[20]
In 1876–77, an England team took part in what was retrospectively recognised as the first-ever Test match at the Melbourne Cricket Ground against Australia.[47] The rivalry between England and Australia gave birth to The Ashes in 1882, and this has remained Test cricket's most famous contest.[48] Test cricket began to expand in 1888–89 when South Africa played England.[citation needed]
The patrons, and other players from the social class known as the "gentry", began to classify themselves as "amateurs"[fn 1] to establish a clear distinction vis-à-vis the professionals, who were invariably members of the working class, even to the point of having separate changing and dining facilities.[29] The gentry, including such high-ranking nobles as the Dukes of Richmond, exerted their honour code of noblesse oblige to claim rights of leadership in any sporting contests they took part in, especially as it was necessary for them to play alongside their "social inferiors" if they were to win their bets.[30] In time, a perception took hold that the typical amateur who played in first-class cricket, until 1962 when amateurism was abolished, was someone with a public school education who had then gone to one of Cambridge or Oxford University – society insisted that such people were "officers and gentlemen" whose destiny was to provide leadership.[31] In a purely financial sense, the cricketing amateur would theoretically claim expenses for playing while his professional counterpart played under contract and was paid a wage or match fee; in practice, many amateurs claimed somewhat more than actual expenditure and the derisive term "shamateur" was coined to describe the syndrome.[32][33]

A phylogenetic study by Jost & Shaw in 2006 using sequences from 18S, 28S, and 16S rRNA supported the monophyly of Ensifera. Most ensiferan families were also found to be monophyletic, and the superfamily Gryllacridoidea was found to include Stenopelmatidae, Anostostomatidae, Gryllacrididae and Lezina. Schizodactylidae and Grylloidea were shown to be sister taxa, and Rhaphidophoridae and Tettigoniidae were found to be more closely related to Grylloidea than had previously been thought. The authors stated that "a high degree of conflict exists between the molecular and morphological data, possibly indicating that much homoplasy is present in Ensifera, particularly in acoustic structures." They considered that tegmen stridulation and tibial tympanae are ancestral to Ensifera and have been lost on multiple occasions, especially within the Gryllidae.[33]
Limited overs cricket is always scheduled for completion in a single day. There are two types: List A which normally allows fifty overs per team; and Twenty20 in which the teams have twenty overs each. Both of the limited overs forms are played internationally as Limited Overs Internationals (LOI) and Twenty20 Internationals (T20I). List A was introduced in England in the 1963 season as a knockout cup contested by the first-class county clubs. In 1969, a national league competition was established. The concept was gradually introduced to the other leading cricket countries and the first limited overs international was played in 1971. In 1975, the first Cricket World Cup took place in England. Twenty20 is a new variant of limited overs itself with the purpose being to complete the match within about three hours, usually in an evening session. The first Twenty20 World Championship was held in 2007. Limited overs matches cannot be drawn, although a tie is possible and an unfinished match is a "no result".[120][121]
