Matchpoint pairs.
The defence started with ace and another diamond, and declarer ruffed the third round high, played two top trumps and led a club from dummy. East took the ace and exited with another club. Declarer threw a heart from dummy and cashed the remaining spades.
I (East) blew it by discarding a heart, so declarer made ten tricks. The way I see it, the secret to reading the hand lies in accurate and informative discarding, and without that I cannot tell if the end position is:
(a).......♠6 ♥K76............(b).............♠6 ♥K76
♥J5 ♣J7......♥Q103 ♣Q...........♥J52 ♣7.......♥Q103 ♣Q
..........♥A982................................♥A98 ♣J
Do you have any advice on how to avoid this? We generally play natural discards (high encourages the suit discarded). Should West discard high-low in clubs to show the jack, or is it better to show length so that East can work out declarer's shape? If we have to switch to signal distribution just for this situation, how do we know which signals we're using? Simple solutions preferred, if possible.
