ECBC Cheat Sheet
                            D.O.N.T. (Disturb Opponents No-Trump)

1. Aim is not to find game, but to find a fit at the lowest level to “disturb”

2. Only use over a strong 1NT opening by opponents (15-18HCP)

3. By overcalling the 1NT opening you promise 7-15 HCP

4. Calls:

X

6+ card suit held  (If Spades >= 12 HCP)

 

2♣

“Clubs and Higher” (5 and 4+ either way)

 

2♦

“Diamonds and Higher” (5 and 4+ either way)

 

2♥

“Hearts and Spades” (5 and 4+ either way)

 

2♠

 6+ Spades (weaker than using a “X” (< 12 HCP)

 

2NT

5+♣ and 5+♦   (Unusual 2NT)

5.Reply to

2♣/2♦
