I have an explicit agreement that overcalls and preempts demand the lead 
from Qx (or Jx if they include the queen), unless opponents are in a strong 
sequence. The tip comes from the late Roger Silberwasser, arguably 
Belgium's best player of all times. Given this principle, 3S would be 
excluded over a limited 2D.

A bit of analysis. Partner didn't mum over 1D. He surely has hearts. He's 
got a fairly strong hand. So he also holds some diamonds, as he didn't 
overcall or double. The hand is a misfit for us.
And even if I'm wrong, at least you've to allow South to reason so.

Best regards
