How can you improve fast if 10~20% of all of your moves on a goban are not using your brain?

Good point! By the way I was going through the game, is this variation viable:

Most of the moves seems sente to me, but I am not on the dan level. Maybe 17 is not sente, but at that point White could just skip it and play 19? Would that have given enough space for two eyes?

Or maybe, if Black resists, then n4 is sente, as well? As far as I can tell only black at m4 “works”, but still White is alive since Black as to defend from the double atari, and White can make two eyes now at h5:

Alternatively to playing 23 at k4, maybe n3 is also good? But that seems like a tough fight.

A lot of those moves are not accurate. like Black should never play move 20 there (in the second variation), it’s filling in Black’s own liberties, basically self-atari. Rather than correcting each move in the variations one by one, it’s better to consult KataGo for questions like these.

White lost because he played too passively for most of the game, and then misread at move 124 during his invasion, losing 18 points in one move. A 7 dan would be sharper and slightly less defensive.
