And it worked! Seven moves later, white realized with terror that black’s shape was too powerful, started wasting ko threats and quickly lost by 4 points.

What about a kangaroo jump? It even has the two o’s you were going for 
I can’t find an actual name for it, probably because it’s less common.

Me (white) against amybot-ddk (don’t ask! 
)
Nice gift wrapped in a box:
Amy didn’t take it. So rude!
From same game: tsumego, doing it wrong!
There were some serious chances for me to lose that game. Amy is so forgiving…

The castle ladder. (Or die grosse Bertha?)
Ok, not my game but i watched it very curious what was the 3d white player plan.
I only realized later that that 3d is a (tricked) bot

I can’t understand where all that came from: I see two ladders where black was able to escape.
At first glance I thought it was a single ladder bouncing and coming back. But it isn’t.

It’s not 2 but 3 ladders running together. There is the link of the game. And yes not very coherent by white but the hidden text can explain that.
