21LA - Responder's 1st bid to a 1NT opening -
level 2 ★
Replies to a 1NT opening.
Your Partner promises you exactly 15-17HCP and a regular distribution. To be able to bid game you must have a minimum of 8HCP.
Two conventions exist to find a major card fit. : Stayman and Texas. They are an absolute must. 1) Without a 4 card major:
PASSE avec moins de 8H
2 SA avec 8H : proposition de manche
3 SA avec 9-10H : la manche
4 SA avec 17H : proposition de petit chelem

Problem E4821 PASS Dont put the Opener at risk - he might have a minimum opening. Even if your P is at his maximum, game doesnt often happen with such a hand!

Problem E4822 2NT with 8HCP; it's your P's choice. Minimum opening he passes, with 16HCP he'll go to game.
2♣ : Stayman
Promises 8HCP minimum
and 1 or 2 of the majors with 4 cards or even a major with 5 and a major with 4
The Opener uses the bidding convention after Responder's 2♣ :
2 ♦ no 4 card major
2 SA both majors with 4 cards
his 4 card major at the 2 level (2 ♥ ou 2 ♠).
Dominique recommends NOT to rebid 2NT with 2 aces.. This convention is totally useless. (cf bidding tips level 3).

Problem E2334 PASS Without any special distribution and only 7HCP - dont take any risks. Here Pass is the correct bid to 1NT.
With a 5 card major and minimum strength. : Texas
This conventions uses the suit just below to bid the one that interests us. : 2♦ for ♥ 2♥ for ♠
The Opener rectifiys on the next round, thus bidding 2♥ (over 2 ♦). or 2♠ (over 2 ♥)
Texas : Enables The Opener to declare the contract. Therefore the strong hand remains hidden from Opps.

Problem E2074 2♥ Thanks to Texas, The Opener is The Declarer. Therefore protecting his ♣,♦ and ♥ honors.
With a 2 suiter hand and at least 10HCP
4♦ : both majors with 5 cards
With a strong one-suiter hand : 3 in that suit shows slam hopes.
