But than your partner would have been able to make another bid, say 4C,
as a move toward 6D
3D is limited. If he has slammish hand he always have a cuebid
♥ or
♣.

Jumping from 3D to 5D kills a lot of space, i.e. the bid
should have a very tight definition range, and assuming 5D is to play, your
partner should be pretty sure, that 5D is the limit.
That's why maybe I should've open 1
♣. I have too much for 1
♦ probably.

Otherwise: [B] playing a artifical system, if you are forced to guess
at the 5 level
I don't understand this. How it is artificial system ?
1D = diamonds, 5+
1S = spades 4+
3D = invitational to game
5D = to play ?
I don't see how you would be any better off in 2/1 or sayc or whatever you consider "natural".
If you mean polish
♣ as whole it's more natural to me than any other system the same way better minor is natural to Americans and Acol is natural to English players... For me playing 2/1 or sayc or SEF is "bothering". Just keep that in mind that "natural" is very subjective thing.

On a side note: I doubt, that you will win a lot, being able to stop in 4D.
Yeah I agree. I don't defend this agreement. The problem is we try to play simple natural system and only introduce special treatments when it's really needed.
Raising partner's suit after he made limited bid is invitatinal, it's basic principle of natural bidding which applies almost everywhere and we didn't find it necessary to change it here.
Maybe (probably) you are right about 4
♦ being better as slammish but then again, it's another thing to remember and we didnt' have this treatment at the time the hand was played.
