all information is good information

Every expert game of minesweeper is the same. In all games you are trying to uncover 480 pieces of information. If you discover that information in chunks of fifty, fine. If you go from 1 to 480 one piece at a time, you still get the win.

It's important to keep this in mind because piece of information has equal value. In my experience, I'd say that one in four games can be won through logic. This means that the vast majority of the time you're going to have to make some educated guesses, or worst case scenario, shots in the dark. When you get to a point where you'll need to make such a move, you want to have figured out every single piece of information you can logically have arrived at. A good way to think about it is that a click that uncovers only a single piece of information is still better than a click that you can't know the result of.

Today's video is done without the shift key which lead to a rare misclick, see if you can spot it! In addition, the last three mines were not arrived at through logic. As near as I can tell there are two possible configurations. I just took a shot and it ended up being right.
