The basic idea is to use transfers in order to give the overcaller a chance to bid twice with very good hands. Initial actions are:
| Dbl= Good 14+, usually balanced |
| 2C = Both majors |
| 2D = Transfer to hearts |
| 2H = Transfer to spades |
| 2S = Spades and a minor |
| 2NT= Hearts and a minor |
| 3C = Natural |
| 3D = Natural |
| 3H = Natural, preemptive |
| 3S = Natural, preemptive |
Note that initial actions are sound overcalls.
Advancer's Actions
After a double following weak notrump bid, some play system on, some play natural. Jump bids show game interest.
