Brian Richardson (read his comment below the diagram) refers to an evaluation of a bidding you can find here:
What went wrong|Minimum hand?* 

These are the hands and bidding in question:

♠	A J 4			♠	6 5
♥	A 10 9 2			♥	K Q 8 5 3
♦	A Q 7 4 2			♦	J 10 6 5
♣	8			♣	9 5

Brian's comment:

In this hand the commentary suggested that East was to blame because of poor evaluation of his hand. Most teachers in the US would put more of the blame on West for poor evaluation. We would take the view that West has 18 Dummy Points and should bid 4 Hearts over East's one Heart response.

I enjoy the website.

Thanks

Dear Brian,

Thank you very much for your input. It could very well be that 4♥  is the best bid with the west hand. Opposite a poor hand with a four card heart suit and say 6-7 points 4♥ will probably not make though. The fifth heart and east's nice distribution make it a good game. Having said that, the answer would have been clearer if west had had a point less.
Probably it also depends of your bidding style and the type of match you are playing. In teams i can live with a direct leap to 4♥ on the west hand, but in pairs I strongly prefer 3♥.
Since I live in Barcelona, Spain, you can imagine I like to bid highly and live freely. See the sunny side as it were.  So let's see what our Norwegian guy has to say.....he will probably bid 2♥ on the west hand :-).

Best regards from Barcelona.

 
Reply from Peter van der Linden ('North'):

I'm sorry to have to disappoint you Ed, but as west I would bid 3♥ in any kind of match.
With one exception: I would bid 4♥ if you were south (favourable lead...).
I think 17 dummy points (I do not see 18) do not qualify for a direct game bid, despite the very strong feature in this hand: the three aces. Don't forget that in the given lay-out it is fortunate that east does not hold any strength in clubs opposite west's singleton.
In order to live up to my supposed pessimism I give this possible east hand:

♠	A J 4			♠	Q 6 5
♥	A 10 9 2			♥	Q 7 5 3
♦	A Q 7 4 2			♦	8 6 5
♣	8			♣	Q J 5

I would put my money on NS if east has to play 3♥, not to mention 4♥.

Best regards from Orkanger.
