If you wore glasses, you'd get it. It's an almost universal image shown inside of a glaucoma test device, which puffs a quick burst of air into your eye. It doesn't really hurt, but it startles you and initiates your blink reflex and causes your eye to water. The blink reflex part is the kicker, though, because blinking before the test is done will invalidate the test and they'll have to do it again. I've sat there upwards of six times through this torture device. Lately, though, my eye doctors use a bump test after putting numbing drops in the eye. I think it's probably more accurate, and it doesn't initiate a blink reflex like the puff test does.
Like the other commented said, this isn't random, but also I'd add that your first ternary option, the ?, should be on the next line; it would make the alignment make more sense to you then, and it would make the block more legible.
Ratings matter, though. A stalemate means your rating doesn't decrease as much as it would have if you'd lost, and you get to take some of your opponent's rating in the process.
