Transfer splinters over a NT opening.
These are bids all on the 3 level directly after a 1NT opening.
These bids show a singleton above the suit mentioned showing either 4441 or 5440 shapes. Or can be 5431/5413 shapes.
Responder bids the splinter suit if maximum and without wastage in the short suit. This is not completely game forcing opposite a minimum for the bid, but does encourage slam investigation.
The opener will not by-pass a major if available.
Meaning of Bids
Let’s look at the meaning of these bids after 1NT:-
- 3♣ – Singleton / void in diamonds
- 3♦ – Singleton / void in hearts
- 3♥ – Singleton / void in spades
- 3♠ – Singleton / void in clubs
Example hands would be:-
- ♠ AQ54 ♥ QJ84 ♦ 6 ♣ KQ107 Bid 3♣
- ♠ 4 ♥ AQ109 ♦ A986 ♣ Q742 Bid 3♥
- ♠ AQJ10 ♥ void ♦ K1072 ♣ QJ32 Bid 3♦
- ♠ KJ109 ♥ Q743 ♦ AK54 ♣ 7 Bid 3♠
Responding by 1NT opener
- 3♥ shows a minimum but 4/5 hearts
- 3♠ maximum and slam try…3NT by responder would be serious slam try
- 3NT – I’ve got good values in hearts…no interest in slam
- 4♣ – slam try in the other 3 suits..4♦ by opener would just be a relay
If the 3X bid is doubled…Pass is to play…RD shows weakness in that suit but shows a good hand. Bids show weakness.
If the opponents have an agreement that the double shows the splinter suit, then RD shows a penalty interest if they sacrifice, bids of the splinter suit shows slam interest and other bids are weak.
You can of course have your own agreements.
