Mostly SA-YC:

  • Strong 1NT (15-17 hcp) w/ Stayman and transfers (optionally including to minors: 2S for clubs, 2N for diamonds)
  • Checkback Stayman (aka Roudi)
  • Weak two's (2D/H/S) with Ogust.
  • 2C is strong (23+ HCP...) with natural responses
  • Gambling 3NT (w/o exterior stoppers)
  • Splinters, control-showing CBs
  • Gerber (after NT)
  • Roman KeyCard Blackwood (with 30 - 14 - 2 with Q - 2 w/o Q responses)
  • 4th suit forcing
  • raises are preemptive rather than inviting (see The Law)


  • Bergen raises
  • Super-accepts on NT transfers
  • Support X/XX.
  • 2-way drury (2C with 3 cards, 2D with 4 cards)


  • DONT over opps' NT opening
  • negative doubles up to 3S
  • Unusual 1NT/2NT (showing the lowest two remaining suits)
  • Michaels CB (showing the highest remaining suit plus another one)
