We use transfers in many competitive auctions 2. Over your natural 1m opening, we play overcall structure: - Double = 15+ and usually balanced - Jump Overcalls are typically two suited - 1N is similar to a takeout x and may be lighter 3. Over your Strong Club, Precision 1D or Balanced or Polish club, we play: - Double = majors - 1N = 4M + 5+m (Raptor) - 2C = both majors - 2D = one major (less than opening hand) - 2M = Intermediate (over a Precision 1D or Balanced Club) or M + side minor (over strong club). - Pass and double shows strong NT + 5. Over your 1N opening we play Woolsey / Multi-Landy depending on range

General Bidding Style

1 may be as light as a nice 10 count NV, but the expected strength is 11. If 1, 1 or 1 do not contain a side major, the openings are very sound, but otherwise may be as weak as 10. In 3rd seat, 2x may be shaded. Preempts range from very light (1st / 3rd NV vs Vul) to very sound (2nd vul).
