A Multi 1C
This includes three types of hand
1/ a 7-11 hand from which the following hand patterns have been removed
A/ a six card major (opens 2D)
B/ a five card diamond suit (opens 1D)
C/ 4-4 or better in the majors (opens 2C)
D/ 5-5 or better in any two suits at the top of the range, no more than six losers (opens 2H, 2S, 2NT)
E/ a flat 9-11 , non vul (opens 1NT)
F/ 11 points with a five card major (opens 1M)
The result of all of this is that this hand will usually hold 3+ clubs, (but it is not guaranteed)

2/ a normal 2C opener in a one club system, which includes
A/ 10-15 a six card club suit
B/ 12-15 5+ clubs and another four card suit

3/ A/ a 12-15 no trump , non vul (prefer one of a suit if sensible)

In reply to this 1C partner distinguishes between opening values and non-opening values. The response of 1D shows opening values and is a game try. If the opponents intervene double replaces the 1D game try

1C 1D
?
1H 7-10 five hearts
1S 7-10 five hearts
1NT 7-8 non vul 7-11 vul no 5 card major, nor both majors
2C 10-15 six clubs transfer continuations (not game forcing)
2D,2H,2S - 4 of that suit 5+ clubs, 12-15 (game forcing)
2NT 12-15 no trump non vul

Less than opening values

1C ?
1H 7-11 five hearts
1S 7-11 five spades
1NT a normal 2NT response, could have majors 2NT by opener is Stayman
2C 7-11 five clubs
2D, 2H, 2S six cards, weak two values

This Multi 1C is for use in a VFP system. In a basic VFP system the bid of 1C shows non-opening values. Opponents bid constructively , doubling 1C with a 1C opener (in their system).
When 1C is a genuine opening bid, the structure of the opponents’ bidding is based on overcall values.
Against a Multi 1C bid the opponents will try to get the best of both worlds. In theory their bidding will be less accurate

I dont see that, what's the difference between this and a standard Polish Club (in terms of explanation, not in terms of content)?

"Weak NT, natural 10-15 with 6 clubs or 5-4, or most 7-11 hands. Almost always 3+clubs if not balanced"

You can get the detail more if you ask, but that should do for a first go.

Having said that, whether it's a useful call, legal, or easy to untangle is another story.

Quite. In the EBU it is illegal to have an agreement to open 7-counts at the one level, so at least here the legality is pretty clear. Now if the lower limit were raised to 8, well now it would require careful reading of the Blue Book.

One important question would be whether a flat 9-11 is passed while a flat 7-8 is opened.

considering his system has, among other goodies, a forcing pass, i doubt his next question was going to concern whether this was a legitimate method for Tuesday afternoon duplicates in Tunbridge Wells bridge club .
