Be Careful with Signalling card

The Six of Diamond On the quarter final of National Club Championship 2006 in Point Square Jakarta, Geologi as a dependent champion meet Djarum Semarang. Djarum consists of Franky Karwur - Santje Panelewen and Supeno-Anhar Haitani. We bet them just 1 imp after loosing 16 imps on first 10 boards, 13-29. One imp that we collected is from the following board.
Dummy
♠ 876
♥ K8
♦ KJ54
♣ J1065
West East
♠ Q543 ♠ KJ2
♥ J3 ♥ Q109765
♦ 10962 ♦ Q
♣ Q72 ♣ K93
Declarer
♠ A109
♥ A42
♦ A873
♣ A84
South open 1NT, when North invites with 2NT, South rejects and plays there. West leads Spade. After hold up spade for 1 round, I play the ♦A, West in order to give signal to his partner, play the ♦6. When East drops his Queen, declarer then collected 4 tricks in diamond. Not only that, declarer managed to collect 9 trick by running the ♣J from dummy. East is the victim of the squeeze in club and heart. -- Jakarta, 3 July 2006

Percentage Play in Grand (2)

I found another grand slam board in the local game. I arrived in the grandslam with the following auction:
NorthEastSouthWest
1H2S3Cpass
3Spass3NTpass
4Cpass4Dpass
4NT pass5NTpass
7C passpasspass
West started with ♦K, plan your play!.
Dummy
♠ J85
♥ AKQ972
♦ void
♣ A765
Declarer
♠ A43
♥ 10
♦ A987
♣ KQ964
How do you proceed? Below are the choice: -Finesse heart, but I think no one will choose this as its percentage is only 50%. -Ruff out the diamond 3 times, but you sort of entries to do this. -Draw trumps, if 2-2, then you ruff out heart to establish it. 4 heart tricks will bring you home. -Draw trumps, if 3-1, then you have to pray to get 5 tricks heart. There is a small variation, when the trumps divide 3-1, when you are in the South, you can finesse the heart. You have better percentage if East had 3 trumps (vacant places). If, West who has long spade, then you have to pray that heart no worse than 4-2. I failed to bring home the contract when trumps divide 3(west)-1(east) and west has 5 heart to the Jack and East has a singleton ♥8. Anyway I have executed the best percentage play.
