I'm after some useful suggestions for 4 level responses to a 1 Major opening (standard style).
Here's a recommendation from another forum a few months ago:

[Marty] Bergen further recommends that the jump shift to the other major shows any splinter raise. First step asks, show up the line. This leaves immediate 4C and 4D calls open, which he uses as:
4C - Balanced 3 card raise, stronger than 3NT (say 16-18) and
4D - Stronger preemptive game raise. Immediate 4M raise weaker.
Jumps to 4 of the other major are preemptive, natural, to play.
