Partnership Understandings: Level 4
7 A 2 : A pass directly after a natural, non-forcing one-level suit opening bid must not show, or usually have, any values.
You may be in that seat holding a hand with values but no suitable suit to overcall, not the right shape for a take-out double and not the strength to overcall 1NT according to your system.
Agreed that pass must not SHOW any values by partnership agreement, but according to the regulation it must also not HAVE any values.
