- 2DHS-4C: Responder can bid 4♣ with huge hand as slam interest, can also bid after asking first with 2NT
- 01122 Responses: 4♦=0, 4♥=1 w/o Q, 4♠=1 with Q, 4NT= 2 w/o Q, 5♣=2 with Q
- XX vs 2NT: We had this come up and asked Radu. Auction was 2D-(X). XX means you want to penalize opponents, it will be better to penalize them than playing 3NT or 5D unless you’re red vs white. 2NT is regular 2NT there, asking for range.
