Happy Birthday Sir Arthur Conan Doyle!

Last year, I noticed that Google had changed their search page to a Sherlock Holmes inspired theme in honor of Sir Arthur Conan Doyle’s birthday. This year, I see that they have chosen to honor Mary Cassatt instead. Well, fine, happy birthday to all, even to Naomi Campbell. But I’ll be listening to some of my favorite Sherlock Holmes stories on my iPod (if you don’t have ’em, try clicking on the first link above, and it will tell you how to get ’em).

Flaws in Milhouse’s Play

While debugging some more challenging positions from The Checker Maven, I encountered the following position which seemed to be giving Milhouse fits.

White to moved, and should be doomed, but isn't against Milhouse.

In debugging the preferred line, it seems to be stuck in a short repeating cycle which it views to be best. In reality, the repeated positions should be viewed as draws, which should be enough for them to reject the line, since the database knows that the line is a win. But my program does nothing to detect repeated positions (I briefly flirted with it, but didn’t like the implementation, so I discarded it.) I’ll have to figure this out to solve positions like this.
