Loved the Google search thing lol Magic Diamond looks interesting. responses to 1♣ look good without interference, but then most systems do well without interference. 1♣ is any 13-16 unbalanced or 15-17 balanced. However, if they get a 2♠ or a 3-level pre-empt I don't like their chances of getting to a good spot, staying out when right or doubling when right.
