 + 4NT is RKC1430
 +
 +2D open
 + 4D is beta ask
 + 4NT is RKC1430
 + Since often suit is not established,​ beta ask is preferred
 +
 +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!
