Please note: North is declarer. (I could not get enough bids into the diagram if I reverse the hands. Please tell me how, in a hand diagram, I can allocate more space for bids than the wizard allows)

The bidding is pretty standard stuff. The opening lead is the ♥6 and the immediate problem is the two way ♦ finesse. (Yes, if ♦ are 3-0 the contract is not cold even if you get the trumps right, but that is true whether West or East holds the length).

It seems odd that a ♠ was not led, which leads one to believe that East has a ♠ honor (or two). That being so, do not the odds favor playing West for ♦ length, since he has 13 unknown cards instead of 12?  I cannot immediately see a flaw in this reasoning, but I don't feel comfortable with it.

Any thoughts?
