6♦ has close to a 40% chance of making
It will be the only making slam in about 10% of all deals
( There was at least one other independent simulation which came to similar conclusions)
Now the hand is difficult to bid over a 3♠ preempt and ♦ as the right strain may often be hard to reach by "normal" methods.
6♦ over 3♠ will sometimes put LHO in a difficult position.
What percentage of those hands find partner with the King of diamonds? I'm not even close to an expert, but with the hand in the post and perhaps with most of the hands in the simulations, I'll give thought to raising partner to 7 diamonds, especially if I take partner at his word and/or swing some myself.
Imagine the problem the 6D bid gives partner on some of the hands. Surely they are as much or more than the problems LHO has.
