Hello,
I'm thinking about memorizing pro games and I was thinking that it would be a nice idea to memorize iconic pro games that have history aside from the game itself...
I'm thinking about "games with a name" such as:

'1582 Triple ko' game between Kashio Rigen and Honinbo Sansa (any detailed comments available?)

'1835 Ear Reddening' game between Shusaku and Gennan Inseki (detailed in Invicible by John Power)

'1846 Blood Vomiting' game between Honinbo Jowa and Akaboshi Intetsu (detailed in Brillance/Power by John Fairbairn)

'1933 Game of the Century' game between between Honinbo Shusai and Go Seigen (detailed in Old Fuseki vs. New Fuseki by John Fairbairn)

'1938 Meijin Retirement' game between between Honinbo Shusai and Kitani Minory (detailed in Meijin's Retirement Game by John Fairbairn)

'1945 Atomic Bomb' game between between Hashimoto Utaro and Iwamoto Kaoru (any detailed comments available?)

Can you think about other famous games worth memorizing and learning about the history?
