In this game, I was white, 7k EGF, playing against 2k EGF. This game showed how weak my endgame is: Katago estimates that I was leading by 10 points/91% winrate at move 147, and yet I lost by 15.5 points.

My reasoning was that threatens to enter my moyo, and at the same time to pull out the stone, so I protected at d. Katago says it loses "5 points". A better way of playing is to make sente moves starting with "c", which threaten to swallow , and protect the moyo afterwards. There are several lines of play, here is a simple one:

What I learnt from pro games is that in the early endgame it's not so much about points but about life and death. In the late endgame it's easier to calculate what is sente and what is the biggest gote. In the early endgame there are so many mutual implications that this is harder. So one first needs to identify the areas where there is or will be major impact on groups, whether they are immediately sente or not.

The border plays that jump to the eye are A and B. A s simply large. B may have that particular quality of impacting the life of the corner group. At first glance if Black plays there it will be sente or at least have large follow-ups.
There is aji to exploit at C and D but nothing major and these moves may be kind of miai.
There are cuts at E and F to make something of the center, but it's probably small.
And then there is G. It makes 6 points already, the shape becomes better, and most of all it cuts Black into two groups. Now both of them are alive but later White will have sente moves against both of them.
I'm not sure this is the best move, but when leading it seems good enough to ensure victory.

@Knotwilg: I didn't try all your moves, but according to Katago, "b" is not bad, while "a" and "g" are even worse than the move I played in my game.
To be fair to myself, I thought B was too trivial to be worthy of exercise, so I looked for something more interesting. With hindsight G is not sente and neither will it bring about much sente against any of the separated groups. B is a sente border play for Black and White has a good follow-up if Black doesn't answer.

And then tenuki! Losing sente so early in the game by capturing at T11 is evil!
(In the actual game, Black captured at T11, which is 4-point mistake according to Katago, but then White protected the cut at P10, which is an equally big mistake...)

If white backs off at S8, this is an improvement on the game. So a fight's about to go down! But unfortunately, black doesn't have the strength to do this here. How does white win the fight?

Compared to the game variation, black is worse and white is better. It's a disaster. The reason things fell apart was white's one random stone at R14 enabling a ladder that forces black to play 2 as shown instead of at a. The followup at a was black's intent when they extended under like this - preventing it means white is better. This is such a clean example of middlegame fighting shape, I was positive it was close to the game until I opened your hide tag

Extend at . Do not be afraid of Black's push , continue with . White doesn't have eyes, but is pretty safe and has a strong wall in the center. The marked white stone is not dead, so Black is not safe either and needs to add a defensive move at "a" or "b".

jlt, I will add my own example in a similar vein to your collection if you don't mind. Sdk should be able to get it right, but I got it wrong in a handicap game I just played. I had correctly assumed my shape was connected, but when my opponent played a move which shouldn't have worked my shape intuition was wrong and I answered too quickly and boom, I made a 20+ point mistake and lost the game.

In the game I played b, but Katago thinks it is 5 points worse than . If Black chooses to respond locally at , then Black only has one eye. Instead of playing at K2, Black may prefer to escape at c.
I got promoted to IGS 5k after an undeserved victory: my opponent resigned while being 1 point ahead according to KataGo. Anyway, here is a joseki question, extracted from the game. The answer should be pretty obvious, but I was careless and played a wrong move. In general I play the opening quite fast in order to save time for the middle game but that's probably a bad habit, it would be better to consider several possible josekis and choose the most appropriate one.
After winning 15/15 games on Fox at 3k level, I got double-promoted to 1k... but then I was afraid that the games would become too difficult so I came back to my 2k Tygem account, to see if I get stuck or if I can manage to rank up there as well.
In the following position I didn't see immediately that Black can play at "a" (White cannot respond at "b", otherwise Black plays "c") but that's not my point. The question is: how to attack White's two stones on the bottom. The answer is rather elementary but I didn't find it during the game.
Position #21: Black to attack the marked white group.

expands Black's corner territory while attacking. After that, White needs to defend at "a" or "b", otherwhite Black will hane at the head of two stones while expanding his corner. White is not safe yet because of the weak point at "c".
In the game I played "f" (after also considering "d" and "e"), thinking this also indirectly protects the cut at H7 but this is not a good attack because White doesn't even need to respond: in case Black plays again in the area, White may still defend at "g" or escape in the center.

Bumping into an opponent's stone is a move I don't consider enough. This sequence is like bumping, with the order of moves reversed. Maybe this should be called "anti-bumping"?
The different areas of the board are not independent, although one is almost so. Anyway, it is still a good idea, I think, to consider how play might go in each identifiable region.
I would have picked the crawl as most urgent.

but Katago's suggestion seems to be superior for the following reasons.
