On this hand, 3NT happened to be the only making game as spades broke 5-1 and clubs 4-1 while the diamond finesse worked.
I was unsure about what 3♥ instead of 3nt would mean. Suppose East bid 3♥. W obviously bids 3♠. Now, if E bids 3NT, does it show better hearts than the fast 3nt does? Which, if any, of the two sequences is likely to have a fifth spade?
I am interested both in "standard" treatments as well as some more intelligent Zelandakh or Kenrexford-like solutions. I thought that 3♦, the cheapest bid, should be some kind of relay and not show diamond tolerance.
In an ideal World, E is able to say "I have doubt about 3NT, what do you think?". Even better if E can also hint at the club fit but I don't think that is necessary.
