Συμεών: and black has secured bottom and center
Συμεών: which is horrible
Secretuse: The point is, it was blacks decition, that strong white walls occured in this game. White oculd not make wall from C14 if black would not make it building.
Συμεών: that is derived from the bad joseki from bottom left

Συμεών: do players often create strong walls in your ranking?
Secretuse: There is good proverb already since ancient Rome. Divide and conquer. :-)

Συμεών: haha
Συμεών: absolutely true
Secretuse: G15 is dividing move, which will not let white to make wall like he did.
