--- Major Opener
Partner opens 1 Heart or 1 Spade. Choose your response by fit and strength:
• Simple raise 2M: 6-10 support points, 3+ trumps
• Forcing 1NT: 6-12, forcing one round, neither promises nor denies a fit
• New suit: your own suit, forcing (1-level shows 4+, 2-level is game-forcing)
• Limit raise 3M: 11-12 support points, 4 trumps
• Jacoby 2NT: game-forcing raise, 4+ trumps
• Splinter: game-forcing raise with a singleton or void
• Preemptive 4M: weak and shapely, 5+ trumps
• Pass: fewer than 6 points
Opener then rebids to describe the hand. Practice from both chairs.
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
