    Opening a weak and gambling 3NT

    This bid is used to describe a hand containing a minor suit of at least seven cards in length and headed by the ace, king and queen, at minimum. The bid has the objectives of preempting the opponents' bidding if they they hold the major suits and trying for a game in notrump on the hope that partner might hold adequate support.
    Because this conventional bid replaces the standard use of opening 3NT (a hand with 25-27 high card points and a balanced distribution), partnerships must use other bids to show the standard 3NT hand

    Responding to a weak gambling 3NT opener

    4♠, 4♥ =  Opener must pass as responder wants to play in a suit game
    4♣  or 5♣   Pass openers 3NT if your suit is clubs
    4♦  or 5♦   Responder takes opener out to diamonds if that is their 7 card suit

Vocabulary - Signals - Leads
▾

Vocabulary

Dealer - first player to bid
Opener - the first player to bid anything apart from Pass
Responder - the openers partner
Overcaller - any bids made by the opposition after the Opener has bid
Declarer - the first player to bid the suit of the final suit, they play their own hand and Dummy their partners hand
Opening Lead - the player to the left of the Declarer who makes the first lead of the game
Dummy - cards placed face up on the table after the opening Lead
Balanced hand - no singleton or void and only one doubleton with no 5 card Major Suit
The Rule of Twenty - A formula to calculate if a hand is strong enough to open the bidding even though the hand may not have 12+ points. Add: Total Points + Count of longest suit in hand + count of second longest suit in hand = If the number is equal to or greater than 20 you can open the bidding

Signals

Attitude This signal is used for showing partner if the suit they led is one you would like to be continued. Play a high card if you want partner to continue leading this suit and play a low card if you prefer them to switch suits

Reverse Attitude This signal is also used for showing partner if the suit they led is one you would like to be continued. Play a low card if you want partner to continue leading this suit and play a high card if you prefer them to switch suits. Low = Like & High = Dislike. The benefit of using Reverse attitude is that you aren't playing a high card out of a suit you like

The Count Use this signal when Declarer leads a suit. When you follow suit with small cards play low - high to show an odd number of cards in that suit. Play high - low to show an even number of cards in the suit you are playing.

Lavinthal Discards When Declarer leads and you can't follow suit throw a card from a suit you don't want, if you throw a high card (meaning 6 or higher) you want back the higher ranking of the other two suits. If you throw a low card so 2-5 then you want back the lower ranking of the other two suits. Although it sounds complex you just basically discarding a suit you don't want.

Suit Preference Most often when you are playing a card which partner will ruff.
Play a high card (6-10) if you want partner to return a high ranking suit and a low card (2-5) if you want the lower ranking side suit

Leads

Which suit should you lead?

Partner's suit If partner has bid a suit, lead it
No Trump Contract Lead a card from your longest suit
A Suit Contract A singleton can promote a ruff for your side

Which card should you Lead?

Never underlead an Ace against a suit contract! Lead the Ace itself if no better lead is available
