2H/2S opening showing 5 - 10 HCP and 5 card in the openingsuit and a sidesuit in minor. You can decide if you use 4+ or 5 in the minorsuit. 5-5 is more safe, but 5-4 is more frequently.

Response:

• 2NT : Ask for sidesuit. After 3C/3D, 3 in the opening suit is invitational.
• New suit : Not forcing.
• 3 in openingsuit : Pre-empt.
