If the dumps defender is marking the dump tight and an easy open side throw can't be done the player with the disk will make eye-contact and engage the dump
The dump cuts across behind the player with the disk and the number 1 in the stack fills to the open side
The player with the disk will bum seal their mark out or use a lefty and throw a floating leading pass in front of the dump that so they can run onto it
If the up the behind dump cut wasn't on then the thrower has the fill available
