Sacrifice contract - Importance of the scoring table



Session program

  • The 1  overcall

After having learnt the 1NT overcall, your pupils will be able to make 1   overcall on a 1 opening.
This session will show them the advantages of an overcall and will teach them how to overcall.

Session first hand (6.2.1)

Directly start with having them play the following hand with North as the dealer.

Have them play the hand another time with West as the dealer...

Lead: A
West wins eleven tricks: six trumps by ruffing once in the short hand and five Diamonds
by finessing the King.
Score : 4   +1 : 450 EW.

Conclusion of these two hands: in a trump contract, it can happen that both sides win a game contract. If South is the dealer, West should have the possibility of overcalling and finding a winning contract for his side. Here again we will be discussing the notion of overcalling.


Conditions for a 1   overcall on a 1  opening

IYou can overcall with 1  on 1   each time you would have opened with 1  , that is as soon as you have 12 HCPs.

Example :

South

North
East
  A J 8 5 3
  K 4
 K 6
  J 9 7 2

But it may also be interesting to say something when you don’t have an opening hand, but at least de 8 or 9 points with one of the two following conditions being true:

  • The hand is irregular (it shows a singleton, two long suits, etc.)
  • or the Spades are very "pretty"(minimum three honors)


Examples :

Further bidding

Raises on the opening are not modified by an overcall.
Raises on an overcall follow the same rules.


Double finesse

You try a double finesse if you are missing two honors.

Examples :

 
  Q J 7
South leads the 2 to the Jack. When he again has the lead, he will play the 5 to the Queen.
  K 10 8 3
  A 9 4
 
  6 5 2

 
  A J 10
South leads the 2 to the 10. When he again has the lead, he will play the 5 to the Jack.

Lead: 10
North can count 13 pts and bids the game on his partner’s overcall.
Declarer: To win, South must take the double finesse to As-Queen of Clubs.
Defence: If the declarer leads the 10 of Spades from the dummy, don’t go up with the King of Spades...
Score: 4   = : 420 NS

Congratulate the declarer who thought of playing the 10 of Spades
