Perhaps much ado about nothing?

And if spades are 4-1 and LHO is any shape other than 4=2=3=4, you will have gone down even though you got the hearts right.

 

Making 3x is worth 11 IMPs against 140 in the other room. Making two overtricks is worth 14. Going down is worth -6. Hence you're risking 17 to gain 3.

 

LHO is limited to 15 HCPs but he doubled 3 facing a one-level response. Regardless of what the double means, do you really think it's less than a 15% chance that spades are 4-1?

On reflection, the question in my final paragraph understates the disadvantages of ruffing two diamonds in hand. With spades 3-2, most of the time this line will just break even.

 

Even without any bidding, the chance of finding trumps 3-2 and diamonds 3-3 is 36% x 68% ~= 24%. So, 24% of the time you gain 3; 28% of the time you lose 17. Not much of a bargain, that.
