What a dilemma accepted insufficient bids make.

In match 7 on board 6 I opened 1♠ with the East hand. Inez misread my 1♠ as 1♣ and responded 1♦.  Pauline was quite happy to accept this bid so she could show her hearts.  Naturally I repeated my spades by bidding 1♠ again.

So the bidding had gone
1♠ P 1♦ 1♥ 1♠ P 

Now Inez was in a quandary, what is forcing?  2♦ does not sound forcing. 2♥ might agree spades or ask for a stopper that she knew I didn't have. Does 3♣ agree clubs?
Eventually she bid 3NT despite having no club stopper.  Pauline assured us that she would have lead the ♣Q against 3NT.

As I had opened the hand with the intention that spades would be trumps I bid 4♠.  

Not quite the Chadwickism "what is an eight card suit?  Trumps!!" but close enough.

A flat board ensued.
