Hello, I played a game recently and missed a game in spades. My partner bid something I was not expecting and wanted to know some expert opinion on what the best bidding for this hand was. Appreciate the help! Question 1: On other boards, East opened with 1S. Whats the expert opinion on this? Rule of 20 does pass. Question 2: Was Wests re-bid of 2 clubs the best bid? If not, why? At another table, West raised to 2S. However I only had 3 spades and assumed the 1S response to my minor was 4 not 5? Is there a convention that I am missing that says this should have been 4? There was no overcall so negative double showing 4 vs bidding showing 5 did not apply. Thoughts? Question 3: East then jumped to 3 diamonds. Although I was not balanced, I figured our best contract may still yet have been 3NT. How could I have known East had 5 spades? Whats the expert opinion on East second bid? If I had east hand I would have jumped 3S to show 5 and a medium hand. Thoughts? Question 4: Although 3NT was down 1, what else would West have bid after that sequence. In hindsight, would 3S have meant to East: "I dont have 4 spades but I do have 3 so bid 3NT if you only have 4 spades and 4S if you have 5"? Thanks for all your help!
