zinger: Black can kill white's group with a, so white needs to live. Playing at a works, but does nothing else. W3 also lives, and is a point or two better. But W1 is even better, as it threatens to make a second eye by descending to B2. If now B2, white lives with W3. This is an example of force before defending.

Velobici: W1 makes life of the enclosed white stones. Locally B2 follows, lest white gain more by playing at the location of B2. In the game, other moves on the board were more important than B2, so it is possible that white will get to play at B2.

The position comes from the fourth game of the Judan title match between Kobayashi Koichi (white) and Takemiya Masaki (black) played on 16 April 1992. Black won by resignation.

The position is discussed in the 53rd issue of The Magic of Go

Dave: However, I think this is not what Kobayashi played, right?

Game continution  

As noted there were various tenuki played but finally after B2 White pushed at W3 and connected at W5.

Bill: Thanks, Dave!

And Kobayashi was, OC, right. As the diagram suggests, Black had territory on both sides. W3 - W5 saves one point by comparison with the suggested solution.
