To be clear I loved Kageyama and his "Lessons in the Fundamentals of Go" and I still do so.

But it is time to have a closer look at his fundamentals ;-)

How much would the direct connection lose in those positions? It looks like in at least two of them, it would make a heavy group. But in the naked peep in the OP, white is not shown to be strong in the area while peeping, and that should matter.

The difference is not much, but in 33% of the pro games (with the position from the OP) not connecting is the better choice.

I had a blind spot for these candidate moves because I am such a Kage fan boy ;-)




aka not blindly follow proverbs and rules but always consider the actual board position
and be careful not to miss candidate moves because of fundamentals

I think this is the key, and it's good to remember at all levels of play. Positions where the intuitive shape move is wrong can lead to an instinctual but wrong play if one doesn't take the time to read.

... and conversely, remember that if you peep, your opponent will not necessarily connect.
