Background: The North American fur trade was the industry and activities related to the acquisition, trade, exchange, and sale of animal furs in North America. Aboriginal peoples in Canada and Native Americans in the United States of different regions traded among themselves in the Pre-Columbian Era, but Europeans participated in the trade beginning from the time of their arrival in the New World and extended its reach to Europe. The French started trading in the 16th century, the English established trading posts on Hudson Bay in present-day Canada in the 17th century, and the Dutch had trade by the same time in New Netherland. The 19th-century North American fur trade, when the industry was at its peak of economic importance, involved the development of elaborate trade networks.
Context: Deerskin trade was at its most profitable in the mid-18th century. The Creeks rose up as the largest deerskin supplier, and the increase in supply only intensified European demand for deerskins. Native Americans continued to negotiate the most lucrative trade deals by forcing England, France, and Spain to compete for their supply of deerskins. In the 1750s and 1760s, the Seven Years' War disrupted France's ability to provide manufactures goods to its allies, the Choctaws and Chickasaw. The French and Indian War further disrupted trade, as the British blockaded French goods. The Cherokees allied themselves with France, who were driven out from the southeast in accordance with the Treaty of Paris in 1763. The British were now the dominant trading power in the southeast. While both the Cherokee and the Creek were the main trading partners of the British, their relationships with the British were different. The Creeks adapted to the new economic trade system, and managed to hold onto their old social structures. Originally Cherokee land was divided into five districts; however, the number soon grew to thirteen districts with 200 hunters assigned per district due to deerskin demand. Charleston and Savannah were the main trading ports for the export of deerskins. Deerskins became the most popular export, and monetarily supported the colonies with the revenue produced by taxes on deerskins. Charleston's trade was regulated by the Indian Trade Commission, composed of traders who monopolized the market and profited off the sale of deerskins. From the beginning of the 18th century to mid-century, the deerskin exports of Charleston more than doubled in exports. Charleston received tobacco and sugar from the West Indies and rum from the North in exchange for deerskins. In return for deerskins, Great Britain sent woolens, guns, ammunition, iron tools, clothing, and other manufactured goods that were traded to the Native Americans.
Question: Who controlled those ports?
Answer: Charleston's trade was regulated by the Indian Trade Commission, composed of traders who monopolized the market

Problem: Background: Rodney George Laver (born 9 August 1938) is an Australian former tennis player widely regarded as one of the greatest in the history of the sport. He was the No. 1 ranked professional from 1964 to 1970, spanning four years before and three years after the start of the Open Era in 1968. He also was the No. 1 ranked amateur in 1961-62. Laver's 200 singles titles are the most in tennis history.
Context: Laver had a long-running, friendly rivalry with Ken Rosewall between 1963, when he started out as a pro, and 1976, when both were semi-retired from the main tour. Including tournaments and one-night stands, they played over 130 matches, all of them as professionals, with some results from the barnstorming pro tours lost or badly recorded. Overall a match score of 79-63 in favour of Laver can be documented. Against the older Pancho Gonzales, whom he played 1964 to 1970 on the pro tour, Laver had a lead of 35-19 or 38-21, depending on the source. Laver had another, even longer rivalry with his fellow Queenslander Roy Emerson. They met first on the senior amateur tour in 1958 and dominated the amateur circuit until 1962, before Laver turned pro. When open tennis arrived in 1968, Emerson joined the pro tour, and had many new battles with Laver. Overall the score is 49-18 in favour of Laver, with 7-2 in major Grand Slam tournaments. Laver had also many battles with Lew Hoad in his first years on the pro circuit 1963-1966. Although he lost the first 8 matches in January 1963, Laver later in the year began to turn around their rivalry, and until 1966, he had built a 38-21 lead. Against Arthur Ashe, Laver had a head-to-head lead of 21-3, winning all of the first 18 matches. Ashe's first win came in 1974, when Laver was 35. Another younger rival in the Open Era was John Newcombe, whom Laver led 16-5 in their head-to-head score.
Question: Who did he play 130 matches against?
