The revised IMPrecision notes apparently use this response. What are the responses over 2N?

Also, do the Jacoby 2N type hands now go via the strong relay?

I'd like to know what IMP is -- but to get the ball rolling: over partner's 1M, more sophisticated treatments are available, but we now play a simple set of responses:

• Raises = PRE
• 2N = ART Sound 4-card raise to 3 or 5.
• 3N = ART Sound 4-card raise to 4.
• Jumps = SPL 4-card raise to 3 or 5.
• Double-jumps = SPL Sound 4-card raise to 4.

After the sound 4-card raises we play trial-bids and serious notrump.
