A1 Joseki

    Keywords: Joseki, Humour

I recently overheard a discussion on kiseido about the A1 Joseki, which starts by playing the four corner points and then playing kosumi (cannot remember for sure). This is a very aggressive opening, possibly leading to very high wins (366.5 points) - and of course equally high losses.

Does anybody know details? Was this just a hoax? How does this strategy work in practise?

A1 Joseki


unkx80: Where does White play? Playing so low on the board, I think this joseki is not good for Black. Most probably it is a hoax. Especially B1, it does not surround any territory at all.


It all becomes clear once you realise that A1 could also mean April 1.


schmorp?: That would explain the "very high losses" (White plays normally) and "very high wins" (in case White gets totally confused and resigns) ;)


mes?: "Very high wins" happens when black is much stronger than white and playing for money, using these silly opening moves to draw a sucker in for the kill.


Dave: Go is a zero-sum game of course. The explanation above never claims that the A1 joseki leads to very high wins for Black :-)

See answering the 1-1 play.


sjd123: I'm sure it's a prank. No one would seriously play there. Would they?

Warfreak2: I would have no objection to playing this opening as Black against a double digit kyu...
