♣♦♥♠
Goobers did well.
You may not approve of South's failure to bid 1
♥ holding 4 of them to the seven. However, players do sometimes fail to bid these awful suits and occasionally it works out for them.
West should discard the Jack of
♠, which in just about any signalling system denies the Queen. If West were trying to make an honor signal trying to encourage the suit, West would signal with the highest he could afford. Holding the QJ, if he wanted to encourage with an honor signal, he would play the Queen, not the Jack. So East should deduce that this is not an honor signal of encouragement, but rather a message saying that "Declarer has the Queen!"
Of course,
any ♠ discard by West should discourage East from continuing that suit (why would partner discard a good
♠, of any rank?), but as was stated, why not be emphatic ? Hopefully your partner knows about honor signals and will get the message.
If he doesn't get the message of the Jack of
♠-- then probably nothing is going to work for you on this hand. Certainly not the 2 of
♣, which such a dufus partner will just read as a negative for
♣ (if he doesn't get honor signals, he's certainly not going to get fancy methods like odd/even or the like).
If he does get the message, then he must lead the KING of
♥ when he gets in with his
♦.
Incidentally, if South plays the Ace over the Jack of
♦ and then cashes the King and leads another diamond from the board to force out the Queen, West should continue to throw away his
♠. Even a dolt partner may be able to work it out now.
