P 4club P 5club///
Opening Lead D-X, made 7. My partner devalued his D-K, but he knows that I am going to bid 5C so on the way he could have shown his H void/singleton.



(ii)Bidding in this system

W N E S
- - - 1 club
P 1 spade 2 diamond 3 club
P 4 heart
(Splinter in H, showing singleton .Though it is void,you cannot jump to 5H because it will cross 5C game.)
P or Dbl. 4NT
P 5 diamond
(1 key card i.e. S-A)
Dbl. 6 club*///

*North has shown min. 8 pts which will be in S,D & C. He has shown 1 key card i.e. S-A & C-Q (by splinter showing one honour) so bal.pts will be min. S-Q. In view of 2D overcall by E, D-K will be with E. So Dia loser will be taken care on spade Q. So only one H loser.

(iii)Had there been no interference by East with 2D, then bidding would be :

S N

(16+ any dist.)
1S
(8-11 and natural)

Note:Even without C-K, Q & H-J in South hand i.e. with only 4 pts, still G.S. is making (i.e. with just 19 pts)

(D-A is wasted value against void)

*Very tempting to bid six spade in view of 3 cards Club support of KQ but in view original pass, N cannot have H-A.

For slam C-A & S-K are necessary with H-A, it will be 11 pts. in which case N will open bidding & not pass.

Bidding explanations:

1) 1 club 16+ pts, any dist.(Note:Though I had 15 points, I did not open 1NT because of major singleton. Hence I lied and opened 1C. There was no other bid to show 14-15 pts at that time.)
2) 1 heart 12+ pts, any dist.
3) 2 diamond 16-18 & min 5 cards suit (in view singleton Major, I did not bid NT. I lied again in D showing 5 cards suit instead of actual 4 cards).
4) 3 club Min. 5 card club suit.
5) 4 spade Splinter in S (singleton)(Min. 4 cards support with one honour in trump).
6) 4NT RKC in club (showing no wasted value in spade suit).
7) 5 heart Two key card i.e. heart - A & club - K
8) 5NT King asking
9) 6 diamond One king (i.e. diamond - K)
10) 7 club As opener has shown only 10 pts so far (heart - A, club - K & diamond - K) & no pts. in spade, hence he has to have balance pts in queens & jacks of heart & diamond. Thus you have min. 5 tricks in club, two ruffs in Dummy, 3 tricks each in heart & diamond, totalling min.13 tricks.

Bidding explanations:

2) 1 heart Artificial/Strong bid, showing 12+ pts. (relay for addl strength).
3) 2 heart Natural, showing 16-18 pts & min. 5 cards heart suit.
4) 2 spade Natural, showing min. 5 cards spade suit.
5) 4 diamond Splinter in diamond i.e. min. 4 cards with one honour in spade and diamond Singleton.
6) 4NT RKC in spade showing no wasted value in diamond (note:- I did not show singleton in heart because it may create confusion in view of partner's suit. He may take it as heart support also).
7) 5 club 0 or 3 key-cards i.e. club - A, diamond - A & spade - K in view of 1C opening.
8) 5 diamond Trump Q asking bid.
9) 5 spade Yes, I have (Step II reply).
10) 5NT King Asking.
11) 6 diamond One King, either heart - K or club - K.
12) 6 spade In case of heart - K (5 trump tricks, 3 ruffs, 2 in heart & 1 each in diamond & club)
13) 7 spade In case of club - K (5 trump tricks, 3 ruffs, 3 in club & 1 each in diamond & heart)

Note: With regular partnership, there is simple convention called "improved king asking Bid" where you show lowest king first (instead of no. of Kings). If you play this convention, then you will know that it is club - K (responder will bid 6club showing club - K), now you can bid confidently 7spade (instead of 6spade).
