This isn’t really a tsumego, but I like this little position compiled by Tokee on Sensei’s Library.
If Black simply pushes on the first line then he makes a point in sente, since White has to block to maintain the corner.
If he plays at the 2-2, though, then he can achieve either
- Two points gote
- If White resists then a ko in which Black risks two points
It’s only a one-point endgame difference, but I wasn’t aware of the technique.

I like this problem. It’s something one could easily chuck onto the board in a tournament lunch break.
Black to capture white with two stones
It’s been around for a fairly long time, by the way – the page is nineteen years old and the author says he was shown it by a 3d at a club.

The first one is a beautiful ishi no shita.
The other two are twin problems of situations you might regularly encounter.
