I think you’ve misunderstood the Korean pro chatter. 77 attracted attention because it is a fairly obvious mistake to a strong player, and pretty much the first mistake black made in this game. The 1-2-3 principle applies, and better to directly play at 79 without making the lossy 77-78 exchange as white can’t resist or you capture the stone on second line which is ample compensation. 73 was a nice move, but one I would probably play as it’s a follow up of the previous move. It was 71 at k13, the one point jump to centre and tenuki from left side which really won my admiration in this area. To have the whole board vision to make this move at this time is very strong play. Of course AI agreed with it.
