Let me ask you this: Do you think that, with an unknown partner of unknown capability, you will be able to explore for a fit in all three of your suits after partner opened in your singleton, establish that fit and have a decent slam investigation?
I won't claim it's impossible, but I consider that overly optimistic. Then, if you look at your hand (and the scoring table), which fit do you mind missing the least? I think the club fit stands out a mile as the least promising: your red suit honors will be useless in a minor suit slam and the probability that you would want to be in 3NT anyway is maximal.
So, I think it is practical bridge to forget about the club suit and limit my search for a fit to the red suits.

Of course, playing with an unknown p the only thing I can be sure of is that if I bid 7NT it will end the auction.
If partner rebids 2
♥ it doesn't matter which minor suit I started with. So the question is if there is a difference between
1
♠-2
♦-3
♦ and 1
♠-2
♣-2
♦ (when opener has diamonds)
and whether there is a difference between
1
♠-2
♣-3
♣ and 1
♠-2
♦-2
♠-3
♣ (when opener has clubs)
As for 1
♠-2
♦-3
♦ vs 1
♠-2
♣-2
♦ (when opener has diamonds), it probably doesn't matter. In both cases we will set trumps with 4
♦ or bid 4NT straight away or maybe just punt 6
♦. The first auction has the advantage that we know that partner is limited so we probably don't have to explore 7. The second may have the advantage that partner is more likely to show the diamonds with a 6-4 shape but who knows with an unknown partner.
As for 1
♠-2
♣-3
♣ vs 1
♠-2
♦-2
♠-3
♣ (when opener has clubs), I am not sure if opener will show the club support if he has QJx in hearts as he thinks we are just looking for 3NT. But OK, our hearts are good enough to make this unlikely. What if he has 6-4? In the first auction we will probably lose the clubs as he will rebid 2
♠ and we probably just bid 3NT then. The second auction, I don't know. Maybe the chance of finding the club fit is a bit better in that case.
What if opener has 3-card diamond support and not too keen on notrumps? Something like 6-2-3-2 with small hearts? It will start
1
♠-2
♦
2
♠-3
♣
3
♦-3NT
?
He may well pass but if he bids on (which would be reasonable), the auction will get out of control and we might as well punt 6NT.
The world would be such a happy place, if only everyone played Acol :) --- TramTicket
