Backdoor

The backdoor technique is a strategic move devised by in Big Brother 5. It required not nominating the intended target to be nominated. Provided they do not win the Power of Veto, the POV holder would then remove a pawn from the block, and the HOH would place the intended target on the block to be sequentiality evicted.

It is a difficult technique to pull off, but if you have a group large enough to carry it out, it can be performed. It requires having 6 players who would agree with the plan, and enough non-HOH and non-nominee houseguests who want to evict the target.

The backdoor was further complicated in Big Brother All Stars when players no longer selected their players, but instead drew names from a bag. If the target won the POV, the backdoor would fail.
