Very good analysis Winston!
The queen of hearts will be left stranded if you take dummy's entry away. Declarer's diamonds are too good!
How can I know that partner does not have 4 clubs and that he is not void in hearts? You can't be sure of course, but there are a few things that tell you that the two unknown hands are as they were in real life.
1. Would partner have led the
deuce of clubs if he was void in hearts? Would he not have led a higher club, alternatively underled his ace of spades in the hope of getting a heart ruff?
2. Would declarer have played low from dummy if he had a doubleton club? Probably not, because he wouldn't have given the defence a chance to get a heart ruff then.
This points towards the killing defence (if there is one). East got it wrong at the table and tried to give partner a heart ruff. Inserting the 8 at trick 1 was both good and courageous, but he fell from grace 1 minute later.
It's so much easier in the post-mortem, is it not?.
