This hand haunted me last night:
Partner opens 1♠ (12-17).
System:
responder
- 1NT = 7-11
- 2♣ = GF
- 2♥ = 9+ with 6°, otherwise 10+/11
opener's rebids after 1NT (natural continuation after any other bid)
- 2♣ = artificial, 15+
- 2♦ = 12-14, nat.
The field is not strong.
What is the contract you would feel well in, playing a.) MP like here, b.) IMP?
How do you bid on according to the given system?
