------This hand was played in "Cumhuriyet İkili Kupasi" tournament in November, 2007. What do you about this hand after your partner opens 2♥ weak and RHO pass.

♠AJ87653--------Vul: None
♥K43
♦AQ
♣A

It is obvious that you gonna play slam but which one? ♠ or ♥. How you gonna find grand slam? If both hands are like this you should play 7♥

♠AJ87653----------♠x
♥K43-----------------♥AQJxxx
♦AQ------------------♦xxx
♣A--------------------♣xxx

However, if both hands are:

♠AJ87653-----------♠Tx
♥K43-----------------♥AQJTxx
♦AQ------------------♦xx
♣A--------------------♣xxx

Better you play 6♠ because if K of ♦ is off you lose one ♦ and a ♠. So, I will advise you to play a nice system over 2M openings. All new suits are NF so, you should bid 2NT as an asking bid.

2♥--------------2NT
3♣(max. unbal.)
3♦(max. unbal.)
3♥(min. with good ♥)
3♠(max.4c ♠)
3NT(max Bal.)

In the original hand partner bid 3♥, now we bid 3♠ as a forcing bid.

W------N------E------S-----Vul:None
----------------2♥-------------Dealer: East
2NT----------3♥
3♠------------3NT(sing. ♠)
---------------4♣ (sing ♣, 3c fit)
---------------4♦ (sing ♦, 3c fit)
---------------4♥ (2 card ♠)

If we learn that partner has a sing ♠ we bid 7♥

W------N------E------S
----------------2♥------
2NT----------3♥------
3♠------------3NT
7♥-------

If partner bid other than 3NT we play 6♠ in order to save the AQ ♦
In real life bidding went like this:

W------N------E------S
-----------------2♥
2NT-----------3♥
4♣-------------4♥
4NT-----------5♣
5♦-----dbl----5♥
6♥----All Pass

After N's dbl to 5♦ it is clear that 6♠ is better than 6♥.
Both hands:

♠AJ87653--------♠T2
♥K43--------------♥AJ862
♦AQ---------------♦T93
♣A-----------------♣T32

It is not an good idea to open 2♥ without a singleton with 5 cards but, all I had was this. Anyway I lost 1♦, 1♠ and a ♥. down 2 for a bottom score.
