PW[Huang Longshi]PB[Zhou Donghou]SO[http://gobase.org/games/china/misc/disks/longshi/game-03.sgf]AW[pd][dp]AB[dd][pp]C[The topic of today is another master player, Huang Longshi. 
Said to be one of the strongest go players of all time, he was born around the year 1651 in China.

By the age of 16, Huang Longshi was 'guoshou' (a national top player) and grew up to be considered as by far the strongest player in China, in his own time and in the centuries after.
The famous Go Seigen ranked him "at least at the level of Dosaku" and  supposedly said that if Huang were alive during modern times, he would be a 13 dan.

His unique style make his game records exciting to study: the moves he plays often look normal and clear, but are based on deep reading. This deep reading shows in fighting situations where he outsmarts his opponents frequently. 
Today we will focus on those fighting types situations. 


What you see here is one of the openings of an even game. Zhou Donghou, who was also 'guoshou' plays black and Huang Longshi plays white. This kind of fuseki is typical of that time. (go back)
