This lets White get a free piece at G2.
E2 would have been better.]

Now all Black has from the F2 area is the ability to connect to the 1 edge.  Before this exchange, Black had the ability to do so in a way that would've left G2 empty.]

C[Eric\:

Since C6 is completely cut off from the K edge, it doesn't matter in this case, but from a narrower view, B10 would've been better, since this gives Black the option of limiting White to a ladder along the A edge.]
;B[b10]
C[Eric\:

Due to D9, this captures C10 and C11, since if White plays either then Black can play the other.  As a result, this forcing move is no weaker than C10 would've been after B10.]
