@quinns just because it has not happened yet does not mean that it will not happen refering of course to the last bit of your post.
Further it is still up to your opponent to resign as they see fit, regardless of how much time you think they are costing you.
When facing zugzwang only heros and fools fight to the (bitter) end... The normal person usualy see when mud hits the fan. To all hopefull halfbakes - I do despise you!!! I do not timeout, my mouse do not slip, I do not make moves before morning coffee, etc. Do not lose time when the game is lost.
