{{family name hatnote|Akaboshi|lang=Japanese}} {{nihongo|'''Akaboshi Intetsu'''|赤星 因徹|extra=1810 – October 19, 1835}} was a Japanese professional 7 ''dan'' Go player.<ref name=SEN>[http://senseis.xmp.net/?AkaboshiIntetsu Akaboshi Intetsu's entry] Sensei's Library Retrieved 28 February 2010</ref>
==Biography== Born 1810, Akaboshi rose to prominence as a student of Inoue Genan Inseki, head of the House of Inoue. By 1834, the former had attained the rank of 7 ''dan''.<ref name=INVINCIBLE/>
Genan sought the prestigious position of the Meijin godokoro, but was unsuccessful as a result of political manoeuvres by Honinbo Jowa. Instead, the title and office were obtained by Jowa with the aid of Hayashi Gembi, an ally within the government. In response, Genan sought to use Akaboshi, his prodigy, in an attempt to embarrass Jowa into retirement.<ref name=BLOOD>[http://senseis.xmp.net/?BloodVomitingGame The "blood-vomiting game"]. Sensei's Library. Retrieved 28 February 2010.</ref>
The "Blood-vomiting game" was played between Akaboshi, 7 ''dan'' as black, and Jowa, 9 ''dan'' as white. It took place at the Matsudaira Go Party from 13–21 August 1835.<ref name=INVINCIBLE>Power, John, (ed.) ''Invincible: The Games of Shusaku'', (Santa Monica: Kiseido, 1996) pp.9-11</ref> Black succeeded in building an early lead, utilising one of House Inoue's secret taisha joseki. However, Jowa played a sequence of three acclaimed tesuji that turned the tide of the match in his favour, ultimately leading to black's resignation after 246 moves. According to ''Invincible'', Akaboshi's health was already in decline when the game began, but after it had ended he coughed up blood over the board and collapsed.<ref name=INVINCIBLE/>
On 19 October 1835, Akaboshi died of tuberculosis.<ref name=INVINCIBLE/>
==Publications==
Akaboshi authored the ''Genran'', a collection of tsumego, published in 1833. It features a total of 69 problems, with the first turn alternating between black and white.<ref name=SEN/>
