I'm not really sure what you mean about best at solving problems in this domain. This was a brute force problem, so the only real skill was in making it as fast as possible. I don't think it was any secret techniques, but rather that they happened to be a group sitting on the right tools at the right time and with a little bit of luck. You can't infer after the fact that it was their genius and domain knowledge that gave them the win, for I'm sure there were many other groups with geniuses and domain knowledge that didn't win, as well as some without the domain knowledge that just didn't get as lucky.
