C[A very questionable move. It does not do anything to prevent White from connecting f8 to either edge. It also does not advance Black's connection. I was vaguely hoping that g9 would serve as an escape piece helping f6, but that makes no sense since g9 does not threaten anything. ]

C[As Eric explained, this was a bad move, as White can now force a 2nd row ladder that has a convenient escape fork at b10.

The next variation shows the move that would have been better.]

C[Now White only gets a 3rd row ladder, for which b10 can be foiled.

This variation was not actually played. Eric explained how it would have likely played out.]

C[Now White pushes a connection along the 1-edge.

As White is completely connected in the A1-corner, Black is now forced to play c4.]
;B[c4];W[b10]
C[In principle, White would like to push from g1 to the k-edge. This will likely result in a ladder along the k-edge, which White will turn along the 11-edge. To make sure this succeeds, White needs to block Black's escape piece, hence the need to play b10 first.]
;B[c9]
C[The only possible response, as the ladder from c6 needs to be foiled.]
;W[e10]
C[This move not only provides a useful stone for White, but also requires a response from Black due to the threat at c11.]
