Your partner promises precisely 15-17HCP with a regular hand. For a game to be possible you will need at least 8HCP
Two conventions are available to look for a potential fir in a Major. They are essential
1) Without a 4 card major :

PASS with less than 8HCP
2 NT with 8-9HCP
3 NT with 10HCP

S	W	N	E

Problem E4821 PASS do not put your camp in danger if the opener's bid was minimum. Even if your partner is maximum, Game will not often succeed with a hand such as yours !

S	W	N	E

Problem E4822 2 NT with 8HCP ; your partner will decide. Minimum he'll pass, with 16 or 17HCP he'll bid game.

2) with a 4 card Major (or two !)

PASS with less than 8 HCP
2 ♣ Stayman with 8+ HCP .

By convention youtr partner will bid :

2 ♦ without any 4 card Major
2 SA with 4 cards in both Majors(système SEF que Dominique ne recommande pas...mais qu'il faut connaître !)
His four card Major at the 2 level (2 ♥ or 2 ♠).

S	W	N	E

Problem E2062 2 ♣ Stayman with more than 8HCP and a 4 card Major.

S	W	N	E

Problem E2334 Without any distributional extra value, and with 7 HCP, do not play with fire . Be reasonable and Pass on 1NT opening bid.

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 :

2 ♦ for ♥
2 ♥ for ♠

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.

S	W	N	E

Problem E2074 Thanks to the Texas transfer, the opener becomes the deavclarer . It is a very useful protection for the honours in ♣, ♦ and ♥.
