"Flag win" flag

[guidopetri]

I'm personally really interested in analyzing games that are "flag wins" - when you run an opponent's time out despite being in an inferior position. It would be amazing to have data on games like this. Unfortunately, it's not as simple as checking the very last position and the time left - lots of people blunder without much time left, so it might involve the flagger purposefully playing quick moves or complicating the position/keeping it complicated in order to induce mistakes or make their opponent take more time to think of moves. I have the feeling it'll end up being an arbitrary number of moves before the last move but this could possibly be mitigated by instead looking at the patterns of time usage across the game.
