Bamboo joint

What's the biggest bamboo joint possible? We all know how the regular bamboo joint works... if W1, then B2.



What if the joint were one stone longer and one line further apart?

Can White connect?

How big can it go, and are there any other rules? (4 long by 3 spaces doesn't seem to work, but I think 5x3 does).

Alex Weldon: The 3x2 one works. Only two things White can try.

Of course, just like the regular bamboo joint, damezumari can become an issue. I don't know how big it can go, but it's mostly an academic issue, because I doubt that good play by both sides could often lead to these "large bamboo joint" shapes.

(Sebastian:) Liberties are even more important than in the 2x1 bamboo joint. If one of Black's sides is all sealed off (similar to a crane's nest) then the connection does not work.
