Nice move discovered during self review with ELF:

It is very strong on many boards.

What is your opinion?

It forstalls :b7: which was common for black when :w6: was popular. AlphaGo wasn't much into defending the :w2: :w4: group and often left it dangling, whereas the human idea was that it's heavy and needed a "base", hence :w6:. So this is not so surprising now. That doesn't mean I think I can play :wc: in your diagram and handle it well, but it's interesting.

So you mean like this one played by Ito Matsujiro 6d in a game against Yasui Sanchi IX 7d played in 1839?
