My first mistake in this game was not realising that my opponent could create a ko with move24 at J1 for the life of his group. Nonetheless I expected this hanami ko to provide me with sufficient leverage to win. Somehow I messed it up or I was wrong to think I had the advantage.
My question is; How would you categorise, conceptualise and quantify a ko of this sort? and how the heck do you even begin to calculate the relative ko threats even on this small board?
Thankyou in advance for any and all replies.
