M J Bridge
Many methods place the emphasis on showing various two-
There is a group of such conventions which have names bearing some similarity to ‘Astro, Aspro, or Asptro’.
Bear in mind that there are numerous versions of these conventions, differing from each other only in detail, but these detailed differences can be important. Even partnerships playing versions with the same name are likely to play them differently in some respect. Make sure that you agree your version. If you are playing some such convention with an occasional partner you must agree the precise details -
Double will usually be played as strong.
The following version of Asptro with its emphasis on the major suits is probably as good as any:-
2♣ at least four hearts and another five-
2♦ at least four spades and another five-
2♥ at least five hearts;
2♠ at least five spades;
2NT at least 5-
As stated previously the decision to overcall will be based primarily on suit quality and length.
In practice, on a two-
If your hand has opening values, or thereabouts, you will be more prepared to stretch the suit quality to some extent, but allow me to emphasise again that hands which feature most of their points in short suits are primarily suited to defence rather than declarer play.
You should be a little more circumspect in your actions if you might have to go to the three-
Be prepared for the possibility that partner is likely to make a forward-
Remember that if you are 5-
If you happen to have 5-

The same hand as above with the minor suits interchanged.
Suit quality is not anything special, and you would have to go to the three-
Pass, although you might just consider 2♣ at favourable vulnerability.
A K 9 7 4
K Q T 6 3
Bid 2♦ promising at least four spades and another five-
If partner bids 2♥ you will rebid 2♠ showing your fifth card in the suit -
partner can always relay with 3♣ in search of your second suit.
Some would double with this hand and lead a diamond in defence.
K Q T 9 6 4
Q 8 2
Replace a small card with ♦J and you would double with good values and an excellent attacking lead.
Note that you cannot bid 2♦. It is restricted to its conventional meaning.
A K 7 4
Q T 6 3 2
You have four hearts and another five-
The hand is weakish and suit quality is not special, but you can stop at the two-
Intermediate and above
In the above I have recommended at least four cards in the major anchor-
This remains my choice.
You should however be aware that many partnerships will have different agreements regarding the lengths in the two suits.
In particular, a requirement for the suits to be either 5-
For me the knowledge that the major is likely to be just four-
If you play most of your bridge against a weak no trump, and you have a taste for a conventional route, then my recommendation is that you should adopt either the present approach (this page) or Landy as a basic method.
Alternatively, you might choose to combine either one of them with D.O.N.T. when facing a strong no trump.
