;W[d6]C[Peter\: This already looks winning for White, since White is connected to the a-edge and Black has almost nothing.]

;W[b6]C[Peter\: Better b7. This connects White but only via b10.]

;B[d9]C[Peter\: This was a mistake, because now White gets b10, finalizing the connection of the central group to the a-edge. Black might have tried b9 instead, threatening that connection. It would not have worked because White can connect both e7 and e9 to the a-edge anyway.]
