There is only one combination from which the Queen is led, regardless of the number of the small cards.
This may be remembered by observing that there is no higher card in the suit than the one led, and that it contains a sequence of three cards, Q J 10. This lead is an indication to the partner that the leader holds neither Ace nor King.
There is only one combination from which the Ten is led, regardless of the number of small cards.
The Ten led is an indication to partner that both Ace and Queen are against the leader.
Combinations from which the Ace is led contain at least five cards in suit, or both Queen and Jack.
This lead is an indication to partner that the leader has not the King, and that the suit is either long, or contains three honours.
