very bad declarer play due to not considering discards in B169 #137

To make the contract you have to solve diamonds for 4 tricks, so you can discard a club. South discards CJ, so CK stays the only missing honour. Ben now plays for club finesse - which is basically a 0% play if the opponent isn't playing completely dumb. So basically you can trick Ben into playing wrong by discarding and creating a "theoretical alternative" because Ben does not consider discards and plays for current suit situation.
