--- Overcalls??  Some hands are too strong for an overcall.
Simple overcalls -- those at the same level as the opening bid -- show
• 7-17 at the 1-level
• 11-17 at the 2-level
With stronger hands, start with a double.  Double then new suit shows 18+.
Overcall then Double is take-out in the 15-17 range.
