I include the rest of the game for the benefit of impressionable youngsters who were excluded from my previous post. This demonstratates the evils of losing your focus. I lost it around move 135, and I suspect from there to the final nail he had at least half a dozen occasions to win. ( My gut feel is that he went the wrong direction in the lower left late in the game, pushing southward near my strength in the lower middle, when he should have been pushing westward to be closer to his strength in the upper left. )
As usual, any constructive comments are welcome.
