This article would share AI's idea on how to limit stones' efficiency!
The situation is actually quite opened, black has many options, but one of the focus is the bottom edge.
Black could consider other big point, but after white 2, black seems to be unable to utilize the triangle stone.
Black 1,3 is an idea to limit white's development, but after white 6 invasion, white is more active. AI believe there is better option for black.
AI suggested white to play 1,3,5 a combination to limit white's development. After getting sente, black could invade at F11. In the progress, H4 is sarcrificed, exchange of 6 and 7 is also painful for black, but black did limit white's development and on the mean time getting a sente. AI's idea is very flexible.
Maybe sente to protect the corner is much more valuable on the 13x13 board, since the middle is way smaller?
