1♣ - (P) - 1♦ - (1NT)
P - (2♠) - P - (P)
P
West alerted 1NT, and when asked explained it as a light takeout with at least 9 cards in the two suits. When dummy came down the director was called and he said he would return after the hand. 2♠ was set one trick on a club lead.
The director was called back and ascertained the following:
- The explanation fit the actual agreement, so east misbid.
- They play "systems on" after natural 1NT overcalls (such as 1♠ 1NT).
- Their notrump system is such that 2♠ is a transfer to clubs, 2NT is a transfer to diamonds.
- They have no agreements about transferring to a suit the opponents have bid. Further, east claimed to be unclear whether 2♥ by west would have been natural or a transfer.
- If 2♠ were a transfer to clubs then 2NT by east would say he likes clubs (would accept an invitation if partner is inviting with clubs), 3♣ would say he doesn't.
- They have no agreements about bidding a suit after the transfer. It is most common in the area to play it as shortness but also relatively common to play it as natural. East claims to never have heard of playing it as shortness, or indeed to having thought about the issue at all. West has heard of that agreement but says they haven't discussed it.
- Without having an auction to go on, south feels he would not have doubled 3♠ but would have doubled 4♠.
- The director polled 3 strong players (there weren't many available) on holding the west hand, partner bid 1NT for takeout, you bid 2♠, and partner rebid 2NT. Two said it does not exist in practice and they would bid 3♠, one said it means partner had a strong notrump and forgot our agreement and he would pass. Here are some more results for you.

(I personally disagree that it can be a strong 4522 since that would double first, but there you have it)
East clearly had unauthorized information from the explanation of 1NT and must be made to bid as though it was explained as strong and natural. By ACBL rules (and I know I'm butchering the wording, I'll let blackshoe correct it) pretty much the director has to determine the worst result for E/W that was reasonably likely. What result is that?
