They open 1NT (mini)

X = 15+ (Next X T/O)
Multi-Landy

(1NT) P (2* ART) ??
X = (13)14+
Overcalls: Natural, Constructive

(1NT) P (2D*) P
(2H) * (P) *

Either side of the table, X=12/15 T/O, Overcalls Nat

(1NT) P (P) ??
If Markey Style includes only PASS with some points, then X is very conservative, usually playing strength with entries rather than just strong balanced.

Overcalls are still Multi-Landy

Balancing Double v Weak NT normally would be around 13+
