Sometimes it is better...

----This hand was played in 6th match of Ankara Open Teams Trials. We have 4 more matches and up to this match our average is 21,6 and it is clear that we will qualify for Ankara finals. In this match we played against a strong team Ergil and lost 22-8 as a big defeat. Lets look at one of the most important boards of this match.
I was sitting at West and LHO opened 1♦ and pass pass holding these cards:
♠KQ95
♥KQ
♦K8
♣Q9865
----I have a clear dbl and your partner bid 3♥ and you bid 3NT. After a ♦ lead you face with these hand:

W----N-----E-----S-----Dealer:N
-------1♦-----p------p----Vul:All
dbl---P-----3♥----p
3NT

♠KQ95-------♠J64
♥KQ----------♥AJ864
♦K8-----------♦J9
♣Q9865-----♣K72
-----On a ♦ lead you see that 3nt is a doomed contract and I lost 4 ♦ and 2 aces for a -200.
If you look at both hands 4♥ is better than impossible contract 3NT. If you think I can bid 4♥ over 3♥ it is not true because my p did not overcall 1♥ over 1♦ and this bid shows poor 5 card ♥ with invitation values. So, how we will manage to reach 4♥.
Here is the suggested bidding:

W-----N-----E-----S----Dealer:N
-------1♦----1♥-----p----Vul:All
2♦-----p-----2♥----p
2nt----p-----3♣
3♥-----p-----4♥--All pass
Firstly, you should overcall this hand, you have good ♥ and enough values for an overcall. Over 1♥ overcall I should not bid 1♠ or 2♣ because they are not Forcing so, I cue-bid with 2♦. And over partners 2♥ rebid now I can bid 2nt, not 3nt because this shows good ♦ stopper. Over 2nt my partner will bid 3♣ and now I will bid 3♥. East will be sure about ♦ stopper and he will bid 4♥.
As west I could have bid:
W----N-----E-----S
-------1♦----1♥-----p
3nt

This shows good ♦ stoppers and average 15 pts. However, we play this as a good gambling ♥ fit.

W----N-----E-----S------So, this sequence will tell partner about good ♦
------1♦----1♥----p-------stoppers
2♦----p-----2♥
3NT

W----N-----E-----S------However, this will show poor ♦ stoppers.
------1♦----1♥----p
2♦----p-----2♥
2NT
Anyway, this board was played 3nt at both tables for down -2. As a result, sometimes we don't need 5-3 fit to play 4M. If we have a weakness in opponents suits we can play 5-2 fit.
