Steinitz was then sent to represent Austria in the London 1862 chess tournament. He placed sixth, but his win over Augustus Mongredien was awarded the tournament's brilliancy prize. He immediately challenged the fifth-placed contestant, the strong veteran Italian Master Serafino Dubois, to a match, which Steinitz won (five wins, one draw, three losses). This encouraged him to turn professional, and he took up residence in London. In 1862–63 Steinitz scored a crushing win in a match with Joseph Henry Blackburne, who went on to be one of the world's top ten for 20 years, but who had only started playing chess two years earlier. Steinitz then beat some leading UK players in matches: Frederic Deacon and the aforementioned Mongredien in 1863 followed by Valentine Green in 1864. This charge up the rankings had a price: in March 1863 Steinitz apologized in a letter to Ignác Kolisch for not repaying a loan, because while Steinitz had been beating Blackburne, Daniel Harrwitz had "taken over" all of Steinitz's clients at the London Chess Club, who had provided Steinitz's main source of income.
