Just had a 9x9 and I wanted to query a couple of things.
The first is that I was (given) lots of opportunities to capture single stones behind my lines and took them. Is this useful? or should I just have left them until they potentially became more threatening.
The second (and the main query). At the mid point in the game I could have captured four white stones to the left of the board by potentially sacrificing one. I didn’t bother because I thought they were dead stones anyway. But then I could not decide whether capturing them is more advantageous than leaving them to be removed as ‘dead’ when the scores are counted. Hence the question.
Game is here and it is not that elegant but you can see the white group to the left at end.
Thanks for any advise!
