The Principles for Responder's 1st Round Bid
| Simplex Principles of 1st Round Responses to Three of a Suit
|
- PRINCIPLE 9: Simplex is a fundamentally natural bidding system. The only gadgets used are 2♣ Redshift, 4NT Blackwood, and the Simplex 2NT.
- PRINCIPLE 10: Responding hands with trump support but less than 10 HCP bid immediately to their total trump level. (For example, after a 1♥ opening by partner, a hand containing 6 HCP and four cards in the heart suit would immediately raise to 3♥. Partner is known to have at least five hearts. Add those five to the four that responder has makes nine. Take six from nine means a raise to the 3-level.) Equally if opener has less than 10 HCP but support for responder's suit, he will bid to the total trump level on the second round.
- PRINCIPLE 11: If a bidder cannot make the first-round bid his hand merits (because the opposition have already taken the auction too high), the bidder simply doubles, with an implied message to partner: "RHO has just taken my opening bid away, and I believe it is safe for you to bid at this or one level higher."
- PRINCIPLE 13: Ignore first-round doubles by the opponents. Carry on and make the bid you would have made if the opponents had passed.
- PRINCIPLE 18: An opening bid, overcall or response of Three of a new Suit guarantees four or more cards in the suit and 17-22 HCP.
- PRINCIPLE 22: Always bid the cheaper of two equal-length suits.
- PRINCIPLE 23: Except for strong (17+ HCP) hands and responses to doubles, four-card suits are never explicitly bid in the first round.
