Hi,
I remember i found years ago a system which was using the opening of 1 heart to gather all balanced hands fron 12 to 17H, maybe also 4441 15-17 (this i am not sure).
Do any of you know from which system it was and where to find the developments - impossible for me to find on the net?
Thanks

• 1♣: 4(+)♥, unbal, any strength, may be a minor canapé.
  
• 1♦: 4(+)♠, unbal, any strength, may be a minor canapé.
  
• 1♥: 9-15 balanced.
  
• 1♠: 16+ [balanced or 6(+)m or exactly 54 in the minors]
  
• 1NT: 9-15 (54) or longer in the minors, no 4cM.
  
• 2♣: 9-15 6(+)♣, no 4cM.
  
• 2♦: 9-15 6(+)♦, no 4cM.
  
• 2♥: Weak (preemptive).
  
• 2♠: Weak (preemptive).
  
• 2NT: 16+ 55 or longer in the minors.

Over the 1♥ the responses are as follows:

• 1♠: Invitational(+) (approx 11+), over which 1NT is 9-12 and then 'system on', while immediate 2♣+ is 13-15 and artificial descriptive.
  
• 1NT: ???
  
• 2♣+: Weak, to play (but may be raised with a good fit).
