Thanks for all this statements. Or should I say for all your opinions? I do believe that all of you have reasons to search the 5-2 fit but may a t least one of you share them with us blind 3 NT bidders?
And at most I am interessted in getting to know how you will reach 3 NT when it is right after your 3 HEart bid. I guess you all give up on this and believe that 4 Heart is always superior?
There is no way you can select between 4H and 3NT correctly 100% of the time having got to this point in the auction. So you have to be aware that if you bid 3NT you will play there sometimes when 4H is better, and if you bid 3H you will play in a suit game sometimes when 3NT is better.
We can start quoting hands at each other where either 3NT is the best game, or 4H (or 4S) is the best game, but that won't prove a great deal other than we are good at constructing hands. The real point is that 3H is much less committal as to strain than 3NT. Having bid 3H you still have a chance of playing in 4H, 4S or 3NT. True, you will sometimes play 4H when 3NT is better, but on some of the hands where 3NT is miles better - if partner has some 2524 hand with Hx in both pointy suits say - he will bid 3NT and you can pass happily. Against that, if you bid 3NT you will play there unless partner has a very unusual hand, because 3NT is an auction-ending bid: by passing over all of 3D (4th suit), 3H (boring preference) and 3S (long spades) you are saying you aren't inviting partner bid over 3NT. Even looking at AKx Axxxx x AKxx (when 4S is by far the best spot) he's might pass 3NT expecting you to have only 4 spades and good diamonds (that's a good bidding problem, except that many people would have bid only 2C over 1S with that hand).
I personally quite like 3D followed by 3NT over 3 of a major on this shape, as that should imply doubt about 3NT as a contract. As long as you are confident (as I would be in my regular partnerships) that 3D is fourth suit forcing; that 3D doesn't imply any additional values; that the sequence shows doubt about the best game, not necessarily a slam try.
