One of the last boards.
There is no barometer but you can estimate position in match as a very close.
You and your Partner keep silance.
Opponents using Wilkosh, and give you full explanation of their bidding.
West 2♦ - 2 suiters, at least 5 cards each, at least one of 5-cards suit is major, 5-11 points
East 2NT - strong request
West 3♣ - club and major
East 3♦ - which major?
rest is natural.
What is your choice?
I know problem like that doesn't have correct answer just want to see didderent people reasoning.
Thanks
