We aim at certain strategic targets when playing against standard bidders using five card majors. If the opponents open 1 of a minor in standard, we want to use whatever means we can to preempt the auction, making it difficult for them to locate their fits. For example, utilizing the preemptiveness of the Intermediate Jump Overcalls, the RJOC are also very preemptive as is bidding a NTO and having advancer preempt at the 3 level. Whenever you eat up a level of bidding, the opponents will be forced to guess at a final contract. It's been our experience that they guess wrong.
The basis for our system is that we trade off ease in handling a few relatively infrequent strong hands to increase our use of lighter and more frequent hands. We, furthermore, try to increase our percentage of success with these more common hands. We use specific description to reduce the strength necessary to compete successfully in an auction. The tradeoff is that less strength is required when less time is needed in the auction to find your proper position. You may be weaker, but if your exposure to danger is shorter, you do not need as much raw power to be relatively secure.
