Open a minor with a 5M-6+m distribution
The 5-3-3-2 and 16 HCP is a little less problematic but should evaluate good or bad 16 and open this with bad 16 and use 1♣ for a good one
Weak 1NT can open with 5 of the major but if using 1NT should be a rag 5 card suit and bid this anytime it is a mid to good suit
1NT - 4-13 HCP
- Could be an escape from spades, favor responding another 4 card suit rather than rebid the 6 card
- Only bid at the low end because you are void
Semi-FORCING
First and Second Seat Opening
2♣ - Game Force 3+ ♣
2♦ - Game Force 3+ ♦
2♥ - Game Force 5+ ♥
2♠ - 3♠ and Constructive (8-11 HCP)
- Suit is help suit game looking for help in that suit
- 2NT is showing top of range with some ruffing values
2NT - Jacoby 2NT
ALERT
3♣ - Bergen Raise Constructive
ALERT
3♦ - Bergen Raise Limit
ALERT
3♥ - Invitational 3 card ♠ (12-13 HCP)

3NT - 1430 Blackwood for ♠
ALERT
4♣ - Splinter
ALERT
4♦ - Splinter

4♥ - Splinter
ALERT
4♠ - Weak Freak or Game force
Weak = 5 ♥s with a singleton or void and max 7 HCP
Game Force = 3 cards support and a flat hand typically 13-14 HCP
Add this because the range is limited it prevents opponents from jumping in thinking it is weak

1NT - Likely 8-10 HCP or less if singleton or void ♠
2♣/2♦ - Two Way Drury
2♥ - 0-6 3+ card support (may consider passing with only 3 card and vul)
2NT - 5-5 in the Minors and no fit in openers suit
