This is a hand from the club tonight. West is known to be a bit of a maverick, often doing things without thinking. Also they do not have a convention card (quite common playing at a regular club evening.
2C was intended as landy (majors), but when asked by North (before doubling), East explained it as natural. North intended his double as penalty (not alerted, just showing clubs), but South thinking it is takeout bids 2D. West now bids 2H and the rest of the bidding was as shown.
The explanation wasn't corrected before the lead and the contract made. After the board, director is called claiming West should never bid 2H with that hand after the 2C bid was misexplained and asks for a ruling. How do you rule?
When you ask them what their agreement is, West insists it is majors and East insists it is natural....
