Did you get it?

We call the shape a ladder because the resulting shape ends up looking like a series of steps. Honestly, it looks more like a staircase, but the Go community has already decided on ladder. Oh, well.

Here's another ladder.

Unfortunately, it's your turn to escape. However, this time, escape is possible.

Good luck!

Could you escape from white's persistent attack?

If there are friendly stones in the path of the ladder, you can escape from the attack because you can extend yourself more quickly.

Go proverbs

Go proverbs are woven through the fabric of the community to summarize wisdom into easy-to-remember phrases.

You will often hear such wisdom dispensed during game commentary or lessons.

Here is the proverb for this lesson.

Don't play Go if you don't know the ladder.

The main idea behind this proverb is that learning the ladder is not very difficult compared to learning Go as a whole. If one should decide to play Go, one should invest the time to learn the ladder.
