Nearly as good

B2 here is nearly as good. The difference is that after W3, black can't afford to jump to B6 immediately, but has to exchange B4-W5 first. Compare the position of B2 in this diagram with B2 in the diagram above.

Mistake 19

If B2 here, then White can sacrifice two stones and take sente to play a big point next.
