The Laws state that, throughout an innings, "the ball shall be bowled from each end alternately in overs of 6 balls". The name "over" came about because the umpire calls "Over!" when six balls have been bowled. At this point, another bowler is deployed at the other end, and the fielding side changes ends while the batsmen do not. A bowler cannot bowl two successive overs, although a bowler can (and usually does) bowl alternate overs, from the same end, for several overs which are termed a "spell". The batsmen do not change ends at the end of the over, and so the one who was non-striker is now the striker and vice-versa. The umpires also change positions so that the one who was at "square leg" now stands behind the wicket at the non-striker's end and vice-versa.
Under Kohli's captaincy, India was unbeaten in 19 Test matches, starting from a 3–0 series win over New Zealand and ending with a 2–1 series win over Australia. India has an unbeaten streak of winning 9 consecutive Test series as of Dec 2017, starting with a 2–1 series win over Sri Lanka. India also became only the third team after Australia and South Africa to have won their most recent Test series simultaneously against all the other Test playing nations. As per winning percentage in Test matches, Kohli is India's most successful test captain, having won more than 61% of Test matches (at least 2 games).
Before a match begins, the team captains (who are also players) toss a coin to decide which team will bat first and so take the first innings. Innings is the term used for each phase of play in the match. In each innings, one team bats, attempting to score runs, while the other team bowls and fields the ball, attempting to restrict the scoring and dismiss the batsmen. When the first innings ends, the teams change roles; there can be two to four innings depending upon the type of match. A match with four scheduled innings is played over three to five days; a match with two scheduled innings is usually completed in a single day. During an innings, all eleven members of the fielding team take the field, but usually only two members of the batting team are on the field at any given time. The exception to this is if a batsman has any type of illness or injury restricting his or her ability to run, in this case the batsman is allowed "A Runner" who can run between the wickets when the batsman hits a scoring run or runs. The order of batsmen is usually announced just before the match, but it can be varied.
Sunil Gavaskar took over as Test and ODI captain in 1978–79, leading India in 47 Test matches and 37 ODIs, winning 9 Tests and 14 ODIs. He was succeeded by Kapil Dev in the 1980s, who captained for 34 Test matches, including 4 victories. Kapil Dev led India to victory in 39 of his 74 ODIs in charge, including the 1983 Cricket World Cup. Kapil Dev also captained India's 2–0 Test series victory in England in 1986. Between 1987–88 and 1989–90, India had three captains in Dilip Vengsarkar, Ravi Shastri and Krishnamachari Srikkanth. Vengsarkar took over the captaincy from Kapil Dev after the 1987 Cricket World Cup. Although he started with two centuries in his first series as captain, his captaincy period was turbulent and he lost the job following a disastrous tour of the West Indies in early-1989 and a stand-off with the Indian cricket board (BCCI).
India has had six regular Test captains since Mohammad Azharuddin took charge in 1989. Azharuddin led the team in 47 Test matches from 1989–90 to 1998–99, winning 14, and in 174 ODIs, winning 90. He was followed by Sachin Tendulkar, who captained the team in 25 Test matches and 73 ODIs in the late 1990s; Tendulkar was relatively unsuccessful as a captain, winning only 4 Test matches and 23 ODIs. He was replaced as ODI captain by Ajay Jadeja and then by Sourav Ganguly.
NKP Salve Challenger Trophy – Started as the Challenger series by the Board of Control for Cricket in India in 1994–95 and later named as NKP Salve Challenger Trophy in 1998–99.

In September 2007, Mahendra Singh Dhoni was named as the new captain of the ODI and T20I teams, after Dravid stepped down from the post. Soon after taking up the captaincy, Dhoni led the team to the inaugural World Twenty20 title. Anil Kumble was appointed Test captain in November 2007, but retired from international cricket in November 2008 after captaining in 14 Tests. Dhoni succeeded him as the Test captain, making him the captain in all formats. Under the captaincy of Dhoni, the Indian team held the number one position in the Test rankings for 21 months (from November 2009 to August 2011), and set a national record for most back-to-back ODI wins (nine straight wins). Dhoni also led the team to victory in 2011 Cricket World Cup and 2013 ICC Champions Trophy. Thus, Dhoni became the first captain in history to win all three major ICC trophies, namely- ICC Cricket World Cup in 2011, ICC World Twenty20 in 2007 and ICC Champions Trophy in 2013. He is widely regarded as India's best ever captain. However, the team performed poorly in away Tests from 2011 to 2014 and Dhoni retired from Test cricket in December 2014, with Virat Kohli being named as the new Test captain. Dhoni resigned as captain of the ODI and T20 teams in January 2017 and Kohli succeeded him at the position.
