;W[bs]C[After this move, I felt like forfeiting; I thought I had taken it to account but indeed I hadn't. As can be seen, I lost both the corner and the whole left. However, my (futile) struggle managed to do some odd things.. I'm including the rest of the game without comments.

When we reviewed the game, it seems that an alternative move earlier would indeed have killed the corner.]
