This gives White a free peep at G9.  Black should've played F10 instead of G10.

White could respond here.  This captures k3 and i5, so Black lost all of Black's potential here.

(For example, without this exchange, Black might at some point play j3, threatening i5.)]

C[Eric\:

In fact, this move captures K2 and reconnects to the K-edge, so it is strictly better.]

C[Eric\:

H7 also lets White connect, so this instead seems better, since this helps Black towards the 1-edge.]
