The player bid 2♦, Multi, and his opponent asked the TD whether this was legal, because he understood it was illegal to psyche the Multi.
The answer was simple enough: this was a Level 4 event, and the restriction on psyching the Multi only applies at Level 3. But it got me thinking. Suppose this had been a Level 3 event: what would we have done?
The actual regulation reads:
EBU Orange book 2006 rev 2009 said:
11 G 6 Multi 2♦
The Multi 2♦ must contain a weak option and one or two strong options.
{a} Weak option
Permitted strength:
A defined range of no more than 5 HCP, a minimum strength of 4 HCP and a maximum of 12 HCP.
The agreed strength may differ according to position and/or vulnerability, but only one range is allowed at any combination of position and vulnerability.
Permitted distribution:
Suit: the suit may be played as either
(1) Hearts; or
(2) Hearts or Spades
Length of suit: the length of the suit may be played as any one of
(1) 6+ cards
(2) 5+ cards
(3) 5+ cards, denying a 5332 shape
The minimum length of suit may differ according to position and/or vulnerability, but only one length of suit is allowed at any combination of position and vulnerability.
{b} Strong options
Permitted strength:
Minimum ‘Extended Rule of 25’ (see 10 B 4).
Permitted distribution:
One or two of the following may be played:
(1) an Acol Two: the suit need not be specified.
(2) a 4-4-4-1 (or 5-4-4-0) hand, with a defined range: the singleton/void
need not be specified.
(3) a balanced or semi-balanced hand with a defined range; alternatively
may be played so that on occasion it may contain a singleton.
(4) a game forcing hand.
Note: Since the Multi 2♦ has only continued to be allowed at Level 3 because it was a popular agreement long before the present approach to permitted agreements was adopted, the following restrictions have been imposed upon its use:
(i) The weak option may be played to show Hearts, or either major; it may not be played just to show Spades.
(ii) At least one strong option must be of reasonable frequency.
(iii) The provisions set out here must be adhered to strictly – variations are not permitted.
(iv) It is not permitted to psyche a Multi 2♦ in a Level 3 event.
(v) Responder is expected to explore game possibilities if his hand justifies it opposite the stronger options of opener’s Multi 2♦.
(vi) It is only permitted to pass a Multi 2♦ if responder has good reason to believe that 2♦ is the partnership’s best contract.
How should we have ruled if it had been a Level 3 tournament?
