K6 for black would be a good move! KataGo even thinks it’s a little better than the game move, but white is seemingly ok (ahead by 2 points or so…) by just connecting with a strong shape at M4.
K6-M4 then looks to me like it would be a great sente exchange, but KataGo doesn’t seem to think that it is a very urgent point (it is suggesting all kinds of other endgame moves before it). Maybe the reasoning is that by playing K6-M4, black helps white to connect, while in the game there will still be some problems with that connection later on (coming up in next video ).
But to reiterate what I said in the video, all three options were pretty similar in winrate in the last quiz, so really there were no right or wrong answers. Here are KataGo’s opinions after 30k playouts:
I’ve been trying to mix it up a bit between questions that have one clear best choice, and questions where all moves are good and it’s more a matter of style. I hope that it doesn’t matter too much for the viewer, since the beneficial part is just thinking about the position and forming an opinion (getting the “right” answer isn’t as important as the exercise you get while looking for it).
The A-B choice from the end of part 7 has a clear correct answer (i. e. one of the moves gets significantly worse winrate from KataGo, and there is a concrete reason why). I would be interested to hear any feedback on which type of questions (one correct answer or multiple correct answers) people generally prefer
