In some systems 2♠ shows spades and a minor. In Los Angeles that's often called "Hamilton" but it has another name in other places that I never remember.

Pottage, Cappelletti and Multi-Landy are all names of (almost identical) defences that include this (and there are others too).
Cappelletti, Hamilton, Helms, and I think Pottage all refer to the same convention, independently devised by each of these four experts. Modified Cappelletti and Helms II are also the same convention (but different from Cappelletti or Helms, of course). AFAIK, there is no analog by anyone else to Hello, which is "Helms III" if you will.
