Bergen Raises Over One-of-a-Major Doubled (BROMAD)
Some partnerships play an extension of Bergen Raises after opener's bid has been doubled. This is called "BROMAD". There are several schemes, including one which keeps 3♣ and 3♦ (as above) and adds 2♣ and 2♦ with similar meanings, but with only 3 card trump support. Others simply have one raise at each level for 7-10 HCP (with 3 or 4 trumps), and use Jordan 2NT with 4 trumps and 11+ HCP. Bergen himself indicates that different partnerships have different preferences for which suit to use. In all cases, the direct raise shows a 'pre-emptive' 3 card raise, limited to 6 HCP.

“Growing up human is uniquely a matter of social relations rather than biology. What we learn from connections within the family takes the place of instincts that program the behavior of animals; which raises the question, how good are these connections?”
—Elizabeth Janeway (b. 1913)
“A taste for drink, combined with gout,
Had doubled him up forever.”
