Force straight up so that disc is thrown to Blue 2 or Blue 3.
Disc goes to 3. Red 3 now slides over and forces handler back toward middle. Red 1 takes away throws to the middle. Red 2 comes towards the middle of the field, but must keep an eye on Blue 2. Also note how Red 6 changes position slightly to cover that open area more effectively.
Disc goes back to the middle
Same thing if it's swung over to Blue 2.
And back to the middle again.
