Thank-you very much for that. Going back over the game I was trying to remember what I was thinking when I made certain moves and your comments made me realise that I often get overly focused on one particular outcome which can blind me to better alternatives. A good example is my response to white 64, I was completely intent on trying to keep all the stones in that area connected it didn't even occur to me that there might be an alternative. I think I need to make more effort to consider the impact of my plays if I want to avoid, as you say, harming my own stones.

I might try and see if I can pick up the book on attack and defence you mention in your guide, it sounds rather good.

Thanks again
