White's push into Black's lower left corner is favoured by KataGo.

However, White would be better in the Semeai Variation, if she simply continued with the Main Semeai.

In principle, Black plays 2/2 reductions.
Taking profit outside the Main Semeai area will benefit him in the Semeai Variation.

In the Capture Variation, Black will have to take White's -stones off the board, if he does not want to let White turn his lower left corner into a seki.
