promises
- • 13+ HCP
- • 5+ spades
- • spades ≥ hearts (open 1♠ with 5-5 majors)
conditions
13+ HCP, S:5+, S≥Hwhy
With 5-5 in the majors, always open 1♠ first — you can rebid hearts cheaply at the 2-level but not spades, so show the more expensive suit first.
what happens next
Partner raises with 3+ spades, bids 1NT without a fit, or makes a 2-level new-suit response with 10+.
