Control Swiss Raises/H2>

After opener has bid 1 of a major, responder bids

4C = game-forcing values and 1 or 3 controls

4D = game-forcing values and 0 or 2 controls.

I have seen several different versions of this form of Swiss Raises, but have yet to see a different used in actual competition. If you know of another system used competitively, please contact me via e-mail.
