with a five card Major and without any minimim strength level : Texas transfers
In this convention, you bid the suit just below the one you are interested in :
The opener will 'rectify' on his next bid, with 2
♥ (on 2
♦) or 2
♠ (on 2
♥).
The Texas transfer enables the opener to be the declarer, this way the stronger hand remains hidden and receives the lead.
