What the director has to do is determine what range of strength NS intend their bid to show when they said "8 playing tricks". If that range of strength does not conforms to OB 10B4, then he rules that NS are are playing an agreement which is not permitted. If it does, then it is a misbid or psyche.
The hand shown falls well short of the 8 clear-cut tricks and high card strength of a 1-level opening, described in OB 10B4, so it is not considered a strong hand, and may not be described as such. If the partnership intend their description "8 playing tricks" to include such a hand, then they have a 2-bid which does not conform to OB 11G10, under which a weak meaning which can be a single suiter in any suit is not permitted.
I think you are 95% there, but the other 5% is important and is often overlooked.
EBU Orange Book 2006, on revised 2009, said:
Allowed at Level 4 only
11 G 9 Mixing types
These regulations do permit an opening bid to have a mixture of strong and other meanings at Level 4.
11 G 10 General
Two of a Suit openings may be played as any one or two of the following:
(a) Strong: Any combination of meanings provided that it promises a minimum strength of ‘Extended Rule of 25’ (see 10 B 4).
{b} Any combination of meanings which either:
(1) includes one specified suit of at least four cards; or
(2) has a specification which does not include holding at least four cards in the suit bid, and does not include two-suiters where the suit bid is the longer suit.
Notes:
(i) Responder is expected to explore game possibilities if his hand justifies it opposite the stronger types of his partner’s opening bid.
(ii) An example of item {b}(2) for clarification: it is permitted to play a 2♦ opening as ‘weak with Spades or Clubs’; this would not preclude a pair from opening such a bid on a hand that happened to have a second suit of Diamonds, since length in Diamonds is not part of the specification. But it is not permitted to play it as ‘Spades or Clubs with a second suit of Hearts or Diamonds’, since length in Diamonds is part of the specification.
(iii) Note that there is no limit to the number of types of strong hand included under (a), nor to the number of types included under {b} so long as the requirement (1) is followed, or alternatively so long as the requirement (2) is followed.
By virtue of 11G9 and 11G10{b}(2) above, it is perfectly legal at EBU Level 4 to agree to open 2
♣ on:
♠ Q9754
♥ AK98532
♦
♣ 6
in addition to 19-20 balanced and other "strong" meanings.
However, what the TD does need to establish is what call North and South would expect each other to make on:
♠ Q9754
♥ 6
♦
♣ AK98532
and
♠ A4
♥ 6
♦ 84
♣ AKJ98532
If the TD establishes that there is an (explicit or implicit) agreement to open either of these hands with 2
♣ as well as the 5710 hand South actually held, then N/S do indeed have an illegal agreement.
On the other hand, if the TD establishes that neither of these hands would be opened 2
♣ by North/South then he should determine that the agreement is perfectly legal at EBU Level 4. The hand should then be treated as a misinformation case as "19-20 hcp or 8 playing tricks in any suit" would not have been an accurate description of the N/S methods.
