Well, in Nr. 1 partner can be aggressive as much as he wants, but you hold 7 solid diamonds, probably a good positioned king in a side suit and a singleton? You want to say that he is aggressive but expects partner to bid his 8 tricks so he will pass? If he is not aggressive what kind of insurance is 4♣ in Nr. 2? Aiming for +130, and risking -800 vs. -400 that has a great chance of going down?
