If you play Walsh and bid 1M and later bid 2♦ then that would typically show a weak hand with 4cM and longer ♦?
IMP's:
1♣-(Pass)-1♥-(1♠)
Pass-(1NT)-2♦-(Pass)
??
Is Pass 100% clear here?
Note: We also play support DBL's, so partner can still be 5-5 or 4-6.
Maybe this is all Clear and pass is 100%; would it also be at MP's?
