if play 4♠ as a final contract,I have no confidence to get 10 tricks with deformed distribution,but it is easier to get 9 tricks if play 3nt.
after 3♠ showed a invitational hand with 5♠ plus 11-12p ,I think there are many wasted points in ♦ suit with QJT4 if play trump contract,but my ♦ suit will be useful with a great chance to make.
maybe Robot didn't believe in pd's bidding or wrong judgement.let Robot know that the balance is key.
