: (A 58ad) KataGo, however, being unaware of the consequences on the alternative Main Variation, seems to like solidifying Black's shape in the left centre instead, e.g. with a move at . : : | |
: She could also wait until after her decision point, because Black is par with the Punishment Semeai Liberty Level, and therefore cannot afford to play any move outside the Main Semeai Area. : : | |
: (143 58ae ; 147 58af) KataGo seems to like the wedge in the left centre more. However, even now KataGo still has a penchant for reducing opponent's territory (effective in the Capture Variation) within the Main Semeai Area, which increases the likelihood of being worse off than necessary in the Semeai Variation. | |
Black must not play any reduction. After all the borders of her territories in the upper right are closed, White will play at in the left centre, stopping Black from establishing another point of territory there. | |
Capture Variation: Compared to the superordinate variation, ...
In total, gains and losses compensate for each other. White + 2 => White + 2 | |
Semeai Variation: Compared to the superordinate variation, ...
In total, gains and losses compensate for each other. Black + 4 => Black + 4 | |
