figure 5

jansteen 3d*: I tried to make the game small scale... However, white doesn't have enough space to make a base here, so attacking seems most natural thing to do.
Good move, preventing both r16 or s16.
This move aims at two follow-up shapes: s10, or s13. Both shapes are hard to attack. In this position most normal way to play for black seems variation "Attacking while building".
