Unique professional openings

How about a thread for professional openings which were only tried once, especially cool ones below about ten moves?

Okay, I will let you in on my secret. First I open Waltheri. Then I click on unusual positions and within a few moves more, there is only one game left.
And that is a unique professional opening. It is all so simple.

Yes, and “both” players are 9p :smiley:

Is when they first gave it the board and the rules and didn’t tell it anything else?

This could very well have been the case :smiley:
But in the rest of the game black and white show that they are just a little more advanced.

If you told me it was two 25+kyus I might’ve believed it :slight_smile: It does seem to have picked up a good bit about shapes though.

Probably the most famous game in go history.
Can you guess which one?

The solution

is …
Peeking without trying?
Sorry this is too easy.
First make an effort to guess who plays who.
Later.

I am truly impressed. :clap:t2:
Unfortunately your namesake became the victim of a young lad.
Who was this young lad?
And why did this game became famous?

How unique is this opening?
Btw if I remember well, there is a mistake in the Taisha joseki

The young lad’s name was Kuwahara Torajiro, but he is better know as Honinbo Shusaku.

In this game, veteran Gennan Inseki sprung a new Taisha variation on the young Shusaku. Shusaku made a mistake in the continuation that gave Gennan a clear lead. But when Shusaku played move 127, a spectator noticed that Gennan’s ears flushed red. Apparently Gennan was taken aback by it.
earred
From that point onward, Gennan’s lead gradually disappeared and eventually Shusaku won the game. The story about Gennan’s ears turning red earned this game the name “Ear-reddening game”. I suppose move 127 also inspired the “Divine Move” theme in Hikaru no Go.
