(2) Good diamond raise.
West leads the ♠Q. East plays the ♠6, presumably count. Plan the play.
(1) Game forcing
(2) RKCB 1430
(3) One key card
West leads the ♣2 (low from odd). You play low from dummy and East plays the 4, standard count. After winning the first trick cheaply, you exit (right or wrong) with the ♠Q.
West pitches the ♣6 as East wins the ♠K. East returns the ♣3 to dummy’s king, West following with the 7. How do you continue on the assumption that West started with five clubs and East two?
