Definition of Constructive

Moscito defines a constructive opening as a hand with 6-9 slam points.

Ace:	3 slam points
King:	2 slam points
Queen:	1 slam point
Singleton King/Queen:	0 slam points
Singleton Ace:	3 slam points

Definition of Preemptive

Moscito defines a preemptive opening as a hand that is too weak for a constructive opening.

Most preemptive openings do not have a minimum strength, however, almost all preemptive openings have minimum suit quality requirements. For example, a 3 Minor opening promises two of the top three honors. A Frelling 2 opening promises at least Qxxx in a Major, and 3.25 points.

In some cases, preemptive openings can be made on relatively strong hands. Opening might bid 2 with a balanced 10 count.
