Help
Against a trump contract, I lead A+K from AKxxxx in a side-suit.
Dummy has xx, my gib-partner plays 10+8, and gib-declarer plays small+Jack.
Is there anyway to tell from this, who has the remaining Queen, and who is void?

None that I am aware of. I wish there were. It's funny now that I think about it. They give GIB declarers the ability to falsecard, but they don't give GIB defenders the ability to signal.

Maybe this is one of those restricted choice situations

According to the GIB System Notes:
If that's true, then your partner must have the queen. (Not 100% sure if this is to be trusted though.)

When it's following to partner's opening lead, it will give an attitude signal:
High spot card with an Ace or King
High spot card with a Queen behind dummy's Ace or King
Low in any other situation
High spot card with an Ace or King
High spot card with a Queen behind dummy's Ace or King
Low in any other situation
If that's true, then your partner must have the queen. (Not 100% sure if this is to be trusted though.)

Umm... how can you conclude that?
Dummy did not have Ace or King.
Seems to me the third option would apply...
In this case, gib-pard actually did have the queen, refuting these rules then...?

Huh. I have no idea what I was thinking there. Probably that Gib always seems to signal with an honour rather than a doubleton on the lead, but yeah, those rules are clearly not true then.
