You know you are a Go addict when spring-cleaning time comes and the only thing you want to do is re-oil your stones and clean up your board after a long winter of hard use.
When “Watch your p’s and q’s!” means something different than your parents thought.
What does it mean to you Conrad?
-p/2 ± sqrt( (p/2)^2 -q)
The original, at least in modern times, means to be on one’s best behavior. It was widely used when I was a child, but I think it is probably becoming archaic, as I haven’t heard or seen it used in a long time.
My go variation (which weirdly just popped into my head yesterday) amuses me because there is some sense in it. There is value in watching the professionals to see how to play, and in watching the kyus to see how not to play.
