Some replies on the topic of counting:
While it is certainly a useful competition skill to count the board within seconds, it is not a good argument in this discussion because
Players who quickly evaluate the board within seconds do simply not count 150 things. They have different methods that had to be specially trained. Naive counting in every game does not train these methods at all (just like I recently found out that I have tied my shoelaces completely wrong all my life and have decided to relearn it).
Counting has opportunity costs both in games and in training. My time for go is finite, it is at least debatable whether counting is a good use of this time at a certain level, especially without the methods in point 1.
As long as one does not know what to count, counting is rather useless. If I am not sure if an endgame hane is sente, then my counting will already be off and I should spend the time trying to find out if it is sente. So when I say “I know how to count 150 things”, that does not mean that I do not understand about speed, it means that the priorities are somewhere else.
I am actually not against counting, I am against making it the moral thing to do, especially if the existence of opportunity costs is not even acknowledged.
