My first "Zia cuebid"

Yesterday I was training for the upcoming Belgian Championship for university students. There were a few interesting hands, but this one was my favorite:

Dealer:North
Vul:NS
Scoring:imps
AK64
A
K98
J7542
JT5
J9643
Q43
T8
9732
KQ87
T76
K3
Q8
T52
AJ52
AQ96


The auction went as follows (opponents silent):
1 - 1NT (14+ nat or 15+ bal - GF relay)
2 - 2NT (5+ 4+ - relay)
3 - 3 (14-17HCP, 5431 - relay)
3NT - 4 (4-1-3-5 distribution exactly - sets trump)
4 - 4! (even number of keycards - fake cuebid!)
4 - 6 (cue - woohoo)

It's not a pure Zia cue since it didn't ruin the opponent's lead. Because of our methods however, I had to make a fake cuebid to figure out if partner had a cue, because otherwise I would give him a much bigger problem. This is due to the kickback Turbo. If I would bid 4NT to deny a cue and show a cue, then partner has to go past 5 to show a cue, but he doesn't have the Q which sort of forbids partner to go past 5 as well. This dilemma is quite unsolvable, and I can foresee it since I hold the Q myself. So why make it hard on partner when you have a bid which makes it easy for him?

Note that partner already showed a singleton , so we already know that we have a cue. No harm done. Nobody else in the main bridge lobby (BBO) found this slam. :-)

Hmm, but if you don't know the heart distribution you can't possibly do that safely? Or did I miss sthg?

With his 3NT bid, partner showed a singleton Hearts. So I already know his distribution and there's no problem for me to make a fake cuebid since this suit is already stopped. If partner had a doubleton, it would be unsafe to say the least. In that case however I wouldn't even try for slam anyway, except with a much stronger hand (which will usually have a cue in at least one of the Majors)
