--- Jacoby 2N w/4x showing a void (Leveled)
Five different Opening hands can be described after a major suit open and a Jacoby 2N response. The percentages
are the approximate frequency of occurrence for the various hand types. Use the (Leveled) script to even that out.
• 4x (17%) - any strength with a void
• 3x (22%) - any strength with a singleton
• 3M (20%) - 18+ Semi-Balanced
• 3N (24%) - 15-17 Semi-Balanced
• 4M (17%) - 12-14 Semi-Balanced
