Traps are highest-value when conditions already favour them — wind blowing off the sideline, a tired handler, or a corner of the field that the disc has been pushed toward over several throws. In windy games we will often default to a trap on the downwind sideline because the swing back is the throw most likely to fail in the air.

In our 3-3-1 Arrowhead Zone the cup traps to the sideline when the disc reaches it. In a person defence, the marker can apply a trap force by setting their stance to close the field-side line. Either way, the goal is the same: turn the sideline into a second defender and shrink the picture until something breaks.

The risk of a trap is what happens if the swing goes — the disc moves a long way fast, and the defence has to recover across the field. Trap-and-recover is a coordinated action, not a one-player decision.
