I like the content.

Eternal life is a type of cycle, where the position of the board repeats. Under some rule sets, a game in which such a situation occurs can become void (no result: neither player wins, but neither player loses).
However, eternal life is so rare in games that if one occurs, a Chinese Go text says that:You should buy fish, vegetables, meat and wine And have a good party to celebrate yourself.
This should be the first ever professional games with ‘Eternal Life’ (or Chosei).
This game is more special because it was part of a league tournament so that each player was awarded half a point.

the famous eighteen and a half point trick play
The extension at Black 5 here is the famous eighteen and a half point trick play (also known as the “nineteen point trick play”).
If White falls into this trick play, Black will give up nineteen points in the corner (hence the name “nineteen point trick play”) but get a huge advantage anyway.
I haven’t seen that one before, good stuff! 
Also, just noticed that the second line is referred to as the “fail line” lol
