Love of 3NT

-----Last week on 26-29 October 2007 Turkish Bridge federation succeed one of the most important events for Turkish Juniors by organising Turkish Youth Bridge Championship for the first time. I hope this championship will be held every year with a rising success and be better and better.
In the MP pairs me and my partner Eymen scored 58,17 _ 53,11_ 55,00 and became 4. which was a failure for us. At the Team Matches we had one of the strongest teams (UZUM) however, we couldn't even qualify for the knock-outs. This was really a disappointing thing for us. When I look back I can find many boards that could change our results and will try to talk about them in every match.
There were 2 groups and first 2 teams of the groups played K.O. Yucel team beat us in the first match so we couldn't qualify for the K.O

Rank----A-GR----------VP------AVR
1-------GUNDOGDU---91------18,2
2-------YUCEL-----------84------16,8
3-------UZUM-------------84------16,8
4-------OCAK-------------80------16
5-------OZGUR-----------43------8,6

1. Match Yucel vs Uzum
----Eymen Bedir, my partner was late for the first match so I played with Huseyin Bakan against not an experienced team at all.
This hand was one of the most annoying deals of this match. I had these cards sitting West at the 3. seat:
♠6-----------------Vul-------:-All
♥AKT52---------Dealer--:East
♦AQT64
♣A7
Bidding went:
W------N------E-----S
------------------P-----P
1♥------P-----1♠-----P
3♦------P-----3♠-----P
3NT---All Pass

after ♣ lead both hands:
♠6-----------------♠A9752
♥AKT52---------♥J7
♦AQT64---------♦J975
♣A7---------------♣85
---As you see 5♦ is the best contract and it is hard to bid 6♦ because we have few points. Anyway I won the second ♣ and finessed ♦ but it didn't work so we could take 5 tricks means -400.Other room: 3♦+1. -11 imp
However the appropriate bidding should be like this:
W------N------E-----S
1♥-----P-------1♠----P
3♦-----P-------3♥----P
3NT---P-------4♦----P
4♠-----P-------5♦-- All Pass

On another board our team mates bid 3NT with these cards below and result -400 again!
♠AKJ86------------♠52
♥8-------------------♥QT652
♦75-----------------♦Q9
♣J7432------------♣AKT8
After first match we proved that we have a deep for love 3NT. However, it was an unrequited love. This ended for a 16-14 vp loss.
