King, Queen, Knave, Ten, Only
Lead king, then ten, in all suits.
Queen, knave, exactly, are marked in the leader’s hand.
Here the leader runs the risk, in plain suits, of being blocked if his partner holds ace, and one small one, originally. There is a conflict of advantages and disadvantages; in favour, the Author believes, of the lead of king, if the suit contains only four cards (compare p. 67, bearing in mind that, when that was written, the lead of any card rather than a king, from suits of more than four cards, had not been the subject of consideration).
