Highest stake ko fights in history?

[hzamir]

I'm curious if people can direct me to specific games I can look up that have some of the biggest stakes (point-swing-wise) in the outcome of a ko fight.

(Added bonus for where ko fight started by someone who had a nasty surprise in his mis-estimation of respective threats)

Unfortunately, I can neither get an email from them for a new password for existing account, nor finish the new account process. In both cases, I just don't get any emails back from go4go, not in spam folder, promotions, social, inbox, anywhere.

Can you summarize to tell me if this is a professional match I can look up in my smartgo kifu database? (Or does someone know the problem with getting reset or signin emails from go4go?

To my untrained eye, black looked like total toast from much earlier than the resignation. And that black group in particular doomed from about #166@Q13? (about 120 moves earlier).

The capturing race is hard to read. I asked 15-block Katago to analyze the position at move 248. After 1000 playouts it thinks Black is leading by 17 points. After 200000 playouts it thinks White is leading by 17 points. So for a human the game is probably balanced.

Honinbo Jowa - Hattori Rittetsu (aka Inoue Genan Inseki), 23 October 1814, is worth a glance.

Well that was a fun slaughter, but I guess I'm not high enough level to understand some head-scratching tenukis made by Inoue Genan Inseki to what I thought we urgent threats.

For example I didn't understand move 91 preferring an eyeshape move rather than running south (to the group the ultimately died.
I also didn't get tenuki on move 137, perceiving doom that seemed to me to by move 158.

Kato Masao and Ohira Shuzo's St Valentines Day Massacre of 14/02/1968 is also quite fun though not a super high swing(the ko doesn't get underway until move 217):
