+ | |||

+ | |||
+ | 1NT open | ||
+ | 4C is beta ask | ||
+ | 4NT is quantitative ask | ||
+ | 5NT is grand slam try | ||
+ | |||
+ | Advice | ||
+ | System is aggressive, you don’t need to be. | ||
+ | Against reasonably competent opponents you can’t muscle a contract for which you don’t have the cards. | ||
+ | The strength of this system is its increased accuracy/precision coupled with aggressiveness. | ||
+ | Bid early, tell partner what is going on. | ||
+ | Just because opponents outbid you doesn’t mean they will make their contract. | ||
+ | Don’t sacrifice on part scores, especially when vulnerable. | ||
+ | Opponents don’t have precision, don’t know when to stop, and consequently often overbid. | ||
+ | You can apply the Winning Trick Evaluation Method to opponents bidding | ||
+ | Only double for penalty when you think they will go down 2+ tricks | ||
+ | Bid the system! |
