---  Jacoby Transfer
South opens 1N w/2452+2425+2245+2254+4522 or any 4333, 4432, or 5332 distribution.
Those 5422 hands are the ones where you are likely to have to reverse to show your suits.
HCP adjusted +1 for any 5-card suit unless you have Kx, Qx, or Jx doubleton.
North transfers to Hearts or Spades.
4NT is Roman Keycard Blackwood (1430) with a trump suit agreed, or quantitative (inviting 6NT) in a notrump auction. Keycard responses:
  • 5!C = 1 or 4 keycards
  • 5!D = 0 or 3
  • 5!H = 2 without the trump queen
  • 5!S = 2 with the trump queen
