Best Story..... I shuda bid 3H and only if my P understand that my jump to 3H does not promise 6 cards or more he would bid 4H showing 3 cards ...... And I bid 4nt to listen 5C showing no key cards and I ask HQ by bidding 5D and hear 6C showing HQ and CK and no SK.... By this time I already know my P has doubleton C (4342) or singleton CK (4351) Next I bid 6D to know if he has DK to discard my poor S3..... And I hear 7H saying he has DK and I pass ............. No way to lose Grand Slam........... I regret my 4NT I'm not an expert, and I'm not an advanced player either........ I hope to be advancing player between intermediate and advanced.......... Thank you
