Declarer plays 6♦ with "too many" tricks, and trumps AKT9xxx opposite Jx. He wins the lead , plays the ♦J from dummy , RHO discarding a ♣. Declarer ducks to LHO's ♦Q, wins the next trick, draws 2 (yes 2!) more trumps and claims, showing his trumps, and saying he has an entry to dummy to cash the tricks there. The defense still has a trump left. How would you rule? Would your ruling be different if declarer claimed without drawing the 2 rounds of trumps?
