B - C 12
Thank you for your comments John, all of which I agree with. What can I say in the face of this spectacular collapse of my position in the South West? 'Ooops' doesn't seem to cover it. My 'Teach Yourself Go' book has been useful in naming things: I was well into attempting a ladder when I discovered it was called, well, a 'ladder'. I think the most important single thing I have learned so far from our game is that the position can change very quickly indeed.
