I almost posted my analysis supporting a heart lead, then had to go for lunch, so Ole beat me to it
I am not commenting on the auction, other than to say I don't like it, and really don't like the double....what are we protecting? And thinking 5
♣ is going for a number is lol.
The club A, a traditional 'let's look at dummy' lead is silly. We don't rate to be able to stop a crossruff...if partner gets in to lead a 2nd trump, they're already down, and the opps are idiots.
In the meantime, consider a layout like:
I'm not pretending this 'rates' to be the approximate layout, but it does seem like our best hope is a 4=3 heart fit and an inability for East to quickly dump his third heart before tackling trumps.
And the heart Ace still preserves some chance to find a switch if needed.
To me, it is the only reasonable choice, altho it may not be the winning choice in real life.
