2♠ was weak, but was neither announced nor alerted
3♣ would be a takeout bid over a weak two, natural over a strong two
I was called at the end of the auction because I think the uncertainty over the meaning of 2♠ was now apparent. I pointed out that all meanings of 2♠ openers require either an alert or an announcement, so they all should have been aware that something was missing. I didn't allow any calls to be retracted, and asked them to call me back if they needed me.
I wasn't called back. I didn't ever find out the result on the board.
If the contract had made, do you think NS would have a case for claiming damage?
If the contract had failed, do you think EW would have a case for claiming damage?
