Here to enjoy interesting games. And hopefully to improve my play as I've found that learning more makes the games even more interesting. For me ratings are a good tool for finding opponents at about the same level, again to make the games more interesting. The logical conclusion is that I normally don't see any reason to click the skull. Why stop a good game just because something came up that prevented you from making the move on time.
Tournament Entry Rating is calculated by the formula (CurrentRating + HighestRating) / 2. The entry rating will never drop to more than 100 points below your Highest Rating.
