What happens if we bid diamonds first?
1C- (X) - 1D - (2H)
??
Difficult situation now for opener. In this scenario, original openers 1S is looking a lot better than before!
2S is looking like a reverse, so that is out
3C? probably shows 6 and a stronger hand
3D - this looks reasonable
3H - cue bid raise, is probably too strong for this hand, but I could be convinced of it because the void is so helpful.
3H - p -??
extra stuff in hand, and south knows they have GF values. 3S might not be out of the question, hoping it doesn't look like cue bid in diamonds. new suit here is forcing.
now p can find the hidden spade fit!! 4
and Voila! I'm probably dreaming about how this would go.
1C- (X) - 1D - (2H)
3H - p - 3S - p
