CharlesMatthews: This side formation is good for making territory, using just three stones.
nature: no, i don't think it's a good formation. it's very thin and have lots of bad aji.
Masamune: nature, you're speaking of rather advanced concepts. Could you maybe provide some examples? Why is this page under 'humour'? Confusing entry!
(Sebastian:) That's because an experienced editor (velobici) didn't take it seriously. As he wrote "also humour....is this "term" used anywhere else ?". To answer your request for examples, I just searched SmartGo's collection, and out of thousands of games, there's only one in which this formation occurs in isolation: Honinbo Genjo vs Yasui Chitoku, played 1790. That game did not end well for Genjo, who played the tent in move 82.
