5. 1S OPENING
REQUIREMENT: 10-14 HCP, 4+/4+ minors, may be three-suited
The 1S relay structure is truly symmetric, and also uses a forcing 1NT response similar to the 1D and 1H openings.
|Pass||To play with spades|
|1NT||Balanced or semi-balanced hand, 0-11, forcing.|
|2C||GAME FORCE RELAY|
|2H||Fit showing jump for a minor - 2NT inquires|
|2S||Fit showing jump for a minor - 2NT inquires|
|2NT||Pre-emptive with both minors|
|3H||Pre-emptive with 9 cards in hearts and a minor|
|3S||Pre-emptive with 9 cards in spades and a minor|
Opener is expected to bid a 5-card suit. Exceptionally this
might be 2H or 2S in a 0544 or 5044 hand. Only 1444 or 4144 hands
may be passed.
Further bidding is not constructive.
|2D||Three-suiter with both minors (see 1C opening structure section 2.4 for relay continuations)|
|2H||Reverser: 5+ C, 4D|
|2NT||High shortage, 5+D, 4C, etc.|
