C[Eric\: This move is reversible via f5. If White plays f5 and Black does not follow up connecting via g5, then it would have been better for Black to just play whatever next move Black was planning after the exchange.]

C[Eric\: this move is also reversible, via g10. 

A complicated analysis shows that (if we assume that a6 is connected to the 1-edge), e11 is strategically captured (meaning, although it is not literally captured, the position is equivalent to the one where Black occupies e11). One can then show by case distinction that Black g9, White g10 is no better for Black than not making this exchange.]
