Responder's bid on Opponent's X after Opener's 1 Pique bid

Responder's bid on Opponent's X after Partner's opening 1♠ bid.
Reminders :

With a weak hand (only a few "ugly" points) and a 2 or 3 support fit PASS.
Support fit at the 2, 3 or 4 level with less than 10HCP and a 3, 4 or 5 support fit.
Redouble without a support fit and with 10HCP or more. The best redouble is when you have a void in Opener's suit!
2NT Truscott 10-11HCP and a 4 card support fit.
Suit shifts at the 2 level are indications of weakness and are therefore non forcing
Suit shifts with a jump are 'Meet me' bids (2 suiter with fit)

Problem E5777 Pass with this poor hand : the regular distribution and the 3 low trump cards aren't going to bring any values to your P

Support bids with less than 10HCP
Reminder : In the bidding sequence, 1♠ X, a 2♥ bid isn't very useful; Responder uses this bid to show a weak support fit a max of 7-9HCP and only 3 ♠ cards. This is a classical bid in the international bridge world.

a 3 card fit and 4-6HCP : 2♠
a 3 card fit and 7-9HCP : 2♥
a 4 card fit and less than 10HCP : 3♠
a 5 card fit and less than 10HCP : 4♠

Problem E5784 2♠ weak support bid with only 5HCP but well positioned

Problem E5785 2♥ A stronger support fit with 3 cards and 9HCP. Opener now knows your strength !

With a support fit and at least 10HCP

With a 4 card support fit and no suit with 5 cards bid 2 or 3NT Truscott according to your strength : 2NT is Game invitation, 3NT imposes Game and shows slam interest
With a 4 card support fit and a 5 card side suit, jump shift ('Meet me') bid : bid this 5 carder with a jump or a double jump depending on your strength. A shift bid ('Meet me') at the next level is Game invitation, a double shift jump bid is Game forcing

Problem E4805 2NT Truscott After Opp's X on the opening in a major at the 1 level, the Truscott convention allows the Responder to show approx 11HCP and a 4 card support fit : Opener can now rectify to 3 or 4♠.

Problem E57814♦ jump shift ('Meet me') bid showing an interesting ♦ side suit and a 4♠ card support fit (don't confuse with Splinter)

Other bids

  - Suit shifts at the 2 level ; weak and non forcing. normally showing a nice 6 carder.
  - 1NT : regular distribution with no major this is a weak bid doesn't guarantee stoppers in the overcalled suit.
  - redouble shows P that his team has the point majority and that he should keep bidding to find the correct contract or penalise the Opps with a X.

Problem E5779 2 ♣ Suit shift at the 2 level, non forcing, showing a non-fitted hand and hoping to find another suit.

Problem E5787 XX This hand is worth more than 9HCP and deserves better than a 2♥ bid. Start with redouble, then a ♠ support fit.
