Is the Pendulum zone the same as the spell / trap card zone? I'm not talking about the skills that add two pendulum zone. I'm talking about a duel without such skills where you place the pendulum cards in your spell / trap zone.
"The Pendulum Zones are located in the leftmost and rightmost Spell & Trap Zones. These Spell & Trap Zones are treated as Pendulum Zones as well only if there is a Pendulum Monster (that is not treated as an Equip Card) in that zone, regardless of its complementary zone, but effects that place Pendulum Monsters in Pendulum Zones can still place them in these zones even while they are unoccupied."

The right and left S/T zones are treated as Pendulum zones. Unless you use a skill that gives you Pendulum zones that is.
