Recently, I have become more and more interested in Go. I am quite weak as a player but hope and expect to improve in the years to come. That being said, I am curious about the American Amateur and Professional Go Circuit. Do the Amateur Tournaments lead to a boosted rank and give you a chance to go Pro? If so, what is the age cut off for going pro? I hear it is quite low in places like Japan, but I am only interested in doing so in America really.
