*EW plays "Multi"-defense over weak 1NT-opening:
Dbl: 14+
2♣: both majors
2♦: 6-card major
2Ma: 5-card major and sidesuit in minor
2NT: minors
Lead: ♥5 to A and ♥7 to K and ♥4 to J (East follows with ♥2)
Discards from North: ♠Q and ♠K.
If/when you now play ♦4 to T on table, West discards ♣6.
You are playing in a 60-pair MP field for National championships.
What now?
