--- Basic 1m Opening (beginner)
South opens 1!C or 1!D (12-21 HCP, 3+ clubs or 4+ diamonds). This scenario
practices the natural responses without conventions like Inverted Minors.

North's responses:
• 1!D — 6+ HCP, 4+ diamonds (only over 1!C)
• 1!H / 1!S — 6+ HCP, 4+ in that major
• 1NT — 6-10 HCP, balanced, no 4-card major
• 2NT — 11-12 HCP, balanced, no 4-card major
• Simple raise (2!C / 2!D) — 6-9 HCP with 4+ support
• Limit raise (3!C / 3!D) — 10-12 HCP with 4+ support
• 4 or 5 of opener's minor — preemptive

Reference: https://www.bridgebum.com/responses_to_one_of_a_minor.php
4NT is Blackwood, asking for aces, or quantitative (inviting 6NT) after a natural notrump bid. Responses:
  • 5!C = 0 or 4 aces
  • 5!D = 1 ace
  • 5!H = 2 aces
  • 5!S = 3 aces
  • 5NT then asks for kings the same way
