One place that we do not need a jump bid to show a weak hand is in the passout (PO) seat, also known as the balancing seat. In this seat with a weak hand, say 5-8 HCP, and a long suit, we would not bid; we would simply pass the hand out. Bidding here with so few HCP may give the opponents a chance to reach a better partscore or game that they may not otherwise reach. Since we will not bid in the PO seat with a weak hand and we could make a simple overcall with 9-10 HCP and a long suit, then a Jump Overcall in the PO seat is free to be used to describe a different type of hand that can otherwise be difficult to show.
