This story gets better.
So I was playing in another one later and my internet went out. It's gone off for a few seconds, maybe a minute, very rarely in the past... but tonight it wnet out for almost 2 hours.
And yes, that is more than enough time to blind me out of a HU SNG, even when I have a healthy chip lead against an idiot.
I lost more tonight without playing than I ever have before.
Yay me - new record.
