Another thing about the "Rule of 2,3,& 4". I always heard of it as being a check after the decision is made to preempt and a level is being contemplated. A hand less than an opening, with little defense, good offense, and a long suit, is usually considered a preempt of 2 with 6 cards, 3 with 7, etc. The "rule" is applied, and if off, one reconsiders opening higher, lower, or not at all.
