Note: In Beta ACOL direct splinter bids over a 1Ma opening are NOT used.
In their place we prefer SWISS bids.
Instead we take the opportunity to show the responder's primary suit, usually 5+ cards.
This change of suit is forcing and valuable knowledge for opener when
required to judge slam posiibilities. This follows Fantoni's statement
that it is imperative for a partnership to show their respective suits
early in any auction. Thus we feel direct splinters are contrary to
Therefore responder shows his support through delayed game raise (DGR) limit raises.
We also remind Betaacol players that with (15)16+ HCP and a good 5+
card suit, an immedite single jump is available. Note this is an
automatic trump request and if there is a
negative response you would then give your trump request responses in
the opener's suit. Note the lower end of (15) requires a positive
response to opener's suit.
The picture is entirely different when opener wishes to show at least
game values in partners response suit, whether a Major or minor suit, with a double
jump in a shortage. E.g 1C - 1D - 3H! or 1H - 2D - 4S! or 1D - 1S - 4C. These are genuine Splinters.
Opener can also use our style 'mini splinters' to show his strength
(15)16+ and distribution single-suited - also confirms his suit as 5+
cards - by making a single jump in an unbid short suit
of (1), 2 or 3 cards. This suit must contain A and preferably
a second top honour. Therefore it strictly denies 4 card support for partner but does not deny
a 3 card support - which partner would show at his next bid unless
direction of bidding is changed - e.g responder opts for a NT game (then
he would not likely to have 5 cards in his suit nor would he have support for
your primary suit) or game in your suit etc.
Bidding the 4th suit is forcing but at the same timeis an inquiry
looking to resolve a possible fit for his suit or a NT game or a move
towards an eventual slam.
These mini splinters made on usually on 5332 distribution, compliment our non-forcing 2Ma openings where a 5-4 minimum distribution is required.
