It was played on February 25 and 26, 1943.Go Seigen is regarded as the greatest Go player in the history of Go. We refer to him as a 'living legend' in Korea. He was born on June 12, 1914, so next year (in 2014), he'll celebrate his 100th birthday. By the way, according to the way age is counted in some Asian cultures, Go Seigen will turn 100 this year (in 2013).His style of play was so different from other top pros at the time, and he won nearly all of his ten game matches (jubango).The only ten game match Go Seigen lost was this series against Fujisawa Hosai (4-6 in Fujisawa's favor). However, Fujisawa was taking black in all games and there was no komi. They played with a handicap called 'josen' (black in all games) because Go Seigen was 8 dan and Fujisawa was 6 dan at the time.Fujisawa Hosai was very famous for his mirror Go. He kept experimenting with mirror Go because he wanted to learn all about it.He didn't just mimic though, he spent more time than his opponents did, and he often got into byo-yomi situations (was short of time) in the middle game. He played with the sort of full concentration that Cho Chikun 9p does.There were two famous players named Fujisawa in the Japanese Go world. Fujisawa Shuko (Hideyuki) 9p was the uncle of Fujisawa Hosai, even though he was 6 years younger.Fujisawa Hosai was also the first professional player to be promoted to 9 dan under the Japanese Oteai system (Go Seigen was the second). They played two more ten game matches on even terms when they were both 9 dan (the only two 9 dans at the time) and Go Seigen won both of them.]RE[W+Resign]OH[-B-];B[qd]C[Fujisawa plays black.

He was able to use the ko to finish the game decisively.Throughout the whole game, I couldn't find any mistakes or bad moves for white, and that's very impressive.Top players today still make lots of mistakes. Even though the short time limits of today's games can partially explain this, it doesn't diminish Go Seigen's greatness and uniqueness.Fujisawa Hosai was also one of the best players of his generation, but because Go Seigen was too special, Fujisawa's moves don't seem to be that special in comparison. His greatness was overshadowed by Go Seigen.However, we should remember that he was the only player who ever managed to defeat Go Seigen in ten game match.I hope you've to enjoyed seeing this classic game and can feel some of the differences between this game and modern games. :)Thanks, Commented by An Younggil 8phttp://gogameguru.com/])(;B[pl]C[This is a good ko threat, but ];W[ol];B[iq];W[fp];B[fo];W[ir];B[om];W[ql];B[iq];W[rl]C[Black can't answer this ko threat, and];B[ep];W[sk]C[White's winning by about 10 points. ]))(;B[fq]LB[io:B][dp:C][fp:A][cq:D]C[Black should have played here instead.
