Catching Up 1

Now the Christmas holidays here, I sat down to fix the game replayer problem that has prevented me from updating the blog for the last few weeks. I had thought up an elaborate work-around, and was just in the process of trying it out when I blundered on the real solution. The replayable games were not displaying properly because there was not enough room for them on the blog page. When I clicked on a blog entry, the games displayed properly because there was now only one entry on the screen. So I've set the blog to display three entries at a time instead of seven, and that seems to have solved it. Now to catch up with all the game reports I've missed. I'm going to do this a day at a time, like the twelve days of Christmas, only not so many.To save time,and because the matches were some time ago, I'll just give the match result in tabular form rather than a verbal report.
