Opening lead: ♦3 (fourth-best leads). You play low from dummy, East wins the jack and returns a low diamond, which you ruff, no deuce showing. Plan the play.
Opening lead: ♦4. East wins the ace and shifts to the ♥2. West wins the ace and returns the ♥6 to East’s queen. East continues with the ♥K, West discarding a low club, and now a fourth heart. Plan the play from here.
