2D: Game forcing and asking for Aces

Responses

• 2H: No Aces, fewer than 2 Kings and fewer than 8 HCP. In his next turn to bid responder can bid the most economical suit (never NT) as a double negative.
• 2S: 1 Ace, No Kings, 4-7 HCP
• 2NT: No Aces, but at least 2 Kings or 8+ HCP
• 3C/D: 1 black/red Ace with at least another King or 2 Queens
• 3H/S: KQxxxx in a black/red suit
• 3NT: 2 Aces
• 4C/D/H/S: AKQJxxx

When opener re-bids 2NT the developments are as after 2NT opening.

After a response of 2NT or higher, the principle of fast arrival applies. For example 2D-2NT-3H-3NT-4H is stronger than 2D-2NT-4H.

When opener re-bids 3NT it is round forcing (if the response was 2NT or higher) initiating a Baron-type bidding continuation. He can instead jump to 4NT to sign-off indicating that there are 2 missing Aces…

When his suit is raised, the opener can:

• Make the most economical bid: Kickback asking responder to cue-bid his Kings and the Queen of trumps.
• Trump suit: No K, No Q of trumps
• Another suit (or NT for the suit of the Kickback): No K or Q in trumps, cue-bid of the lowest side K
• Jump in trump suit: K or Q of trumps, no side K
• Jump in another suit (or NT for the suit of the Kickback): K or Q of trumps, cue-bid of lowest side K
• Make another non-trump bid: Asking for the K in that suit (or the suit of the Kickback with NT). Responder can cue-bid a K below Trump suit or bid Trump as a negative. Any higher bid shows the possession of the K that the opener is asking for.

After 2D-2H, a jump in a suit by opener (i.e. 3S/4C/D/H) shows a solid suit and is an asking bid

• NT: At least 1 K
• Suit: No K, but cue-bid of lowest Q
• Trump: No K, no Q

!!! Attention 2D-2H-4H is forcing !!!

Any new suit by opener is a Suit Asking bid.
