Examples in this game would be 140 onwards, and 166 onwards.
In this particular game I very consciously took a bend-but-not-break approach because I was so ahead on points, but I still believe a competent player would be able to stonewall such invasions almost immediately.
I would be grateful for some pointers regarding this aspect of play.
