Yeah that’s what she said:) The invasion was 1 point in profit. Black spent 2 stones to erase 3 of the original 6 points

Yeah she only covered W was 1 point worse but didnt mention 1 also was 1 point bigger.

6-1 is only worth 3 points. 8-2 (5 moves later) is not a cut needed to protect so it's Gote. 13-3 is reverse Gote of 2 points threatening 1 point. This would be the bigger move at that point.

@@slaiyfershin Well, 8-2 is sente if white plays the reverse yose you mentioned. There is no larger yose for white than avoiding 8-2 cut at the point. Hence, in total, 6-1 hane is sente 4 points. The reverse yose you mentioned is reverse sente 2.5 points. Overall, the reverse yose of avoiding 6-1 hane looks way larger than the reverse yose you mentioned.

If black tenuki on top right, white can just go in. You don't need fancy tesuji, every move would be bigger than anywhere else on the board. The oki you mentioned is sente. But we need to be careful because the block on 1-3 is not. That is, after white does the oki, it goes to the bottom right anyway, and the exchange could potentially give black a chance to tenuki on bottom right. In the actual game, black would still need to answer the bottom right hane, so you get the same result as in the vedio. But sometimes it's risky to do such a thing.

@@haidonggong9745 ??? 1-3 is sente. Read the 2-6 cut. After this, black has no way of saving the center group. Did you actually read the value of, for instance, jumping at 9-1? The loss due to this jump compared with the sequence 1 to 6 in the video does not seem larger than the reverse yose of left top 1-3 hane by black. If you say that "just go in" is larger than the reverse yose I mentioned, could you tell me which particular move? Maybe, 9-2 is the best move, but I am still not sure whether the gain by this is larger than the reverse yose.

A lot of people agreed with her so I think she is right (Yeonwoo)
