-- North should bid spades in preference to 2♦; should bid 1♠ limited to 6-ish points or so
- 2♦ could be better defined, 3- spades, 4- clubs, 9- total points?
- 2♠ I think should be F1, show extra values, diamonds presumed agreed and 5+, looking for 3nt/5d if responder has values. Responder shouldn't have spades on this sequence!
