May I suggest another contest?
It would be also very educational. It is not new, do you you remember Epson World Bidding Challenge? Here are the rules:
"The solver has to bid both hands all the way through the auction. You are shown the hands of East and West and are asked to state the best complete sequence, using..." BBO Advanced bidding methods.
...
"In marking the entries, the solver's sequence is compared with the official solution. Marks are scored for each call in the auction in agreement with the official solution.
Ten marks are awarded for the first correct call, eleven for the second, twelve for the third, and so on. When you make a 'wrong' call, you score no more marks on that problem, but keep the marks already won."
Expert players (panel) separately will do the same. When most of them agree on the best sequence, this becames the official solution. If the experts differ, it is ...'s job to adjudicate.

Here are the four problems from 1988. The solution is hidden, members of the panel were Bobby Wolff and Zia, the 'boss' was Omar Sharif.
