C[Peter\: This situation, where White has two stones on the short diagonal, looks very strong for White. Marietje asked Eric how he would play here as Black. See next variation.]

C[Peter\: In retrospect, this is a blunder, because White e5 is an obvious win. See next variation.]

C[This obviously wins\: since c7 and e5 are both connected to the A-edge, so is e7. Then White wins by double threat at f4 and g6.

Because of this, I now think it may be better for Black to play d7 instead of c8. However, then White gets d8 and d9.]
