I'm sorry if this is in the wrong category, as a lot of this post has to do with confusion about databases, but it's specifically in regard to a pro game, so I figured this would be a good place to start. Also this is my first time using diagrams, so sorry if any of them turn out badly!

Waltheri's Pattern Search, GoGoD, and GoBase all list different information about this game. I've attached an SGF from Waltheri. W lists komi as 5.5, but the other two databases list it as 0 komi. Neither of these quite line up with my understanding of the history of komi; I'd expect somewhere from 3.5-4.5. Furthermore, GoGoD lists this as an "insei game", while the other two list it as "Japan Promotion Tournament", which I'd assume refers to Oteai. However, as Chariot pointed out to me in Discord, Takemiya wasn't even a professional until 1965, according to Wikipedia and Sensei's Library, yet all three databases list Takemiya as 1p for this game; Kato, too, is listed as 5p for each of these, but was not a professional until 1964, according to Wikipedia. I just have no idea what to think at this point; does anybody have any idea about the circumstances of this event?
However, the most surprising and confusing thing about all of this (for me, anyway) is that GoGoD's record of the game ends at move 86.

White just played this marked stone, which captures the Black cutting stones. KataGo actually has quite a bit of trouble reading this sequence until several tens of thousands of playouts. Given that this is where the GoGoD game record ended, I assumed that Kato had misread and resigned at this point. I've been memorizing pro games using SmartGo and thought I knew this game inside and out, so you can imagine my surprise after uploading the Waltheri SGF to GoKibitz and seeing a totally unfamiliar ending position!
At 500,000 playouts and assuming 5.5 komi, KataGo evaluates this position as +20.9 points for White.
The rest of the game, as listed on GoBase and Waltheri, I did not have KataGo analyze to 500,000 playouts, since I didn't know those moves existed until today. I set the number of playouts for the rest of the moves to be anywhere from 10,000-100,000, depending on how large the spike in KataGo's initial evaluation of the score was. It seems that after move 86, the quality of the moves is generally not quite so high as the earlier moves (if KataGo's score chart is to be considered a metric for move quality), and the graph fluctuates considerably. This raises the question for me - are the moves after 86 perhaps a study/possible continuation rather than as part of the actual game?
So much confusion on my end.
Anyways, on to the actual game itself - I had a lot of fun going through and memorizing the moves that I did, though some things surprised me. Pre-AI games are pretty new to me, since I really only came to Go after the AI revolution, and primarily watch modern Korean games.
I thought the early sequence on the lower part of the board was pretty cool:

But I was surprised that White didn't add a move to the shape in the lower-right, since this seems to invite a Black pincer later that would make things uncomfortable. I was also surprised that Black played the splitting move rather than push again, since after White's turn, Black's marked move struck me as being a little painful to take in gote:

But I suppose Black is fully alive and has nothing to worry about, and can focus on attacking. The thing is, it really felt to me like Takemiya had sente for most of the game. Bugcat actually left a really interesting history of this move on GoKibitz -
https://gokibitz.com/kifu/ryRc5V8Lt?path=21The first move that really didn't make sense to me was Black's turn at 47:

It seems to me like the whole point of Black's marked stone was to keep the White groups separated, and B could very easily have played that sente circle move before the turn. But because Black turns first, White is able to capture Black's marked stone and become fully connected. From my perspective, it looks like Black ends up getting attacked in the center because of this.
Onto the events leading up to move 86:
Black finds life in the corner, then starts a cutting sequence:

From here, it took me a lot of reading to figure out why these stones are captured, but after Takemiya's attachment/1-point jump, the capture sequence is basically forced if Black tries to escape:

I'm just getting started looking at the rest of the game, but I thought I'd drop in here and see if anybody has any ideas regarding the discrepancies between records.
Full disclosure - I'm planning to make a YouTube video of an analysis of this game, so if you'd rather not have your thoughts heard in that context, please specify as much in your responses.
Thanks so much for your time!
