The partner they have for you does not play spade. He select 0 tricks with two aces, 5 spades and three kings. He will select 7 tricks with nothing higher than a jack. I cannot play with that type of ai. Also, the other team knows what your cards are so, when you know you can go nil (or not go nil but dont have the cards to even take one) the game knows and forces you to a lost hand
