BROMAD

When partner open 1 or 1   and RHO doubles:

2:      Constructive raise 3 trumps

2:      Limit raise 3 trumps

2maj:  Weak raise with 3 trumps

2NT:   Jacoby 2NT forcing raise

3:      Limit raise 3 trumps

3:      Constructive raise 4 trumps

3maj:  Preemptive raise

XX:     10+ 2 or fewer trumps

An interesting modification proposed by Carl Hudecek is to make the 1NT response forcing, opener relays to 2 with a minimum, and responder can pass or bid 2() to show a weak hand with a long suit.
