I was playing with a friend on BBO last night when these two hands arose back-to-back.

Hand #1:

You upgrade your nice 5 card club suit to a 20-21 2nt opener and have a straightforward auction to 6NT, noticing that 6♣ is a much more desirable contract.  I was quite fortunate to receive the spade ace lead, upon which I quickly claimed 12 tricks.  I will make it harder for the BW community and have my LHO lead the diamond Q.  Some hints about the hand: RHO has 4 hearts to the J98, and as you already know, LHO has the spade ace.  How do you go about making this contract?

Hand #2:

You play a forcing 1nt and end up in a pushy diamond game.

LHO leads the club Ace, RHO following with the club 3.  LHO shifts to the diamond 4, you play low from dummy, RHO wins the Ace and continues with the diamond 3, LHO following with the 9 and you win the King in dummy.  What's your plan to make this?

(For those who may ask, the opponents do not have carding agreements as a random BBO pair, and you do not know which card they lead from AK)
