|
What is the first step in planning the defense?
|
Set the goal in your mind! |
|
|
What is the primary goal in defensive play?
|
To set the contract.
|
|
|
What are owed tricks?
|
Owed tricks are tricks the contract implies we should be able to take.
|
|
|
How do we determine the tricks we are owed?
|
The rule of 13 or The rule of 7 |
|
|
What is the rule of 13?
|
Subtract the number of tricks contracted for (x) from the total number of tricks possible (13), equals the number of tricks we are owed (y). 13 - x = y ex: Contract is 4H = Declarer needs to take 10 tricks. 13-10=3, we are owed 3 tricks. |
|
|
What is the rule of 7?
|
Subtract the actual contract (x) from the maximum contract possible (7), equals the number of tricks we are owed (y).7 - x = y ex: Contract is 4S 7-4=3, we are owed 3 tricks. |
|
|
How do you determine how many tricks the defense needs to set a contract?
|
We can add 1 to our owed tricks (x) , equals the number of tricks needed to set a contract (y). x + 1 = y ex: Contract is 3N Rule of 7: 7-3=4, we are owed 4 tricks; 4+1=5, we need to take 5 tricks to set the contract. |
|
|
Regarding setting defensive tricks, what is the rule of 8?
|
Subtracting the contract (x) from 8, equals the number of tricks the defense needs to take to set a contract (y). 8 - x = y ex: Contract is 5D 8-5=3, we need to take 3 tricks to set the contract. |
|
|
What is Guestimating?
|
Guestimating is the process of estimating strength, HCP and potential tricks to come up with an intelligent guess in creating a plan of defense.
|
|
|
How do you estimate your partner's HCP?
|
40HCP - Opponents estimated HCP(x) - My HCP(y) = Partner's estimated HCP(z) 40-x-y=z |
|
|
Vs. Suits: Every ____HCP in partner's hand equals a potential defensive trick.
|
4.5
|
|
|
Vs. Notrump: Every ____HCP in partner's hand equals a potential defensive trick.
|
3.5
|
|
|
How do we estimate the number of tricks we deserve according to our estimated HCP holding?
|
Add your expected defensive tricks (x) to the fuzzy expectation of partner's potential defensive tricks (y) to determine the number of tricks we deserve according to your estimated HCP (z). x+y=z ex: I can see 2 potential defensive tricks in my hand and I estimated my partner has 8 HCP which fuzzily equates to 2 defensive tricks versus a 3 notrump contract, so: 2+2= 4 tricks we deserve. |
|
|
How do we determine the number of tricks we need to develop?
|
Subtract the number of tricks we deserve (y) from number of tricks we need to set them (x), equals the number of tricks we need to develop (z). x-y=z We deserve 3 (y) tricks in a 4 spade contract. We need to take 4 tricks to set them. 4-3=1, we need to develop 1 trick. |
|
|
What are the two primary defensive strategies?
|
Passive and Aggressive
|
|
|
What is the difference between passive and aggressive defensive strategies?
|
Urgency and potential risk
|
|
|
Passive defense is...?
|
When it isn't urgent to get our tricks right away, we don't need to make risky plays.
|
|
|
Aggressive defense is...?
|
When it is urgent to get our tricks ASAP, we are willing to take risks. |
|
|
What sort of defense do Sharks prefer?
|
All things being equal and with little information to know otherwise, Sharks prefer passive defense.
|
|
|
When should we be aggressive?
|
