Bridge plays

Recently I've played quite a number of boards of bridges on my android phone, while some are worthy to be shared.
1) Contract 5D (NS Vul)
Bidding
N   E   S   W
1C  /  1D  1S
2C  /  2D   /
5D a.p.

North
S J83
H ----
D AQJT
C AQJT87

South
S KT4
H A62
D K6543
C 54

West lead D5, how to play?
It would be easy if the distribution is even. However D was 3-1 break while S was 6-1 break, H 7-2 break. We will need a saftier way to make this contract.

In the first turn, we discard S 5 and win by H A. Play small hearts and ruff by D A to make sure that we have bridge to the declarer. Play 2 rounds of D, thrown in to W by C 10 to W's C K. West plays S A, then he'll have no choice but to play D or S, then back to declarer, cash D and let dummy get the remaining C.

What can we do if D is in 4-0 break?...

2) 1NT x + 3
North
S K854
H AJ4
D KT
C KJT6
South
S 76
H QT8765
D J3
C A74

N   E   S   W
                 /
1N X   a.p.

East leads S Q.
This contract can't be defeated. Playing small S and let E to play for the second round, East plays D A and S A, D 7 to D K.
Since East doubled, C Q is probably on E, and we hope that H K is on W. The is correct, and we finally wins 4C and 6 H.
What we want to know is that whether we can play a game. But it may be quite risky as the position of K and As may be bad. However if E leads, they won't have the chance to win the D tricks...
