Thanks. I asked because there were some comments made about how unlikely it would be to find the C:Q switch from C:Qx. Sure, on this hand he had C:Qx and from that holding the switch might be unlikely. But on the conditions of the sim it was not necessary that West had that Club holding. When deciding whether to duck trick 1 it is I think not correct to take into account the unlikelihood of a Club switch based on the assumption that it would be from C:Qx.
