After a bit of misplay I was expecting a disastrous IMPs score on this deal:

---

But no table made game. One table made 10 tricks, but unluckily for them, they were in 5♥. We went three down.

I remarked, after my partner had left, that I was certain the contract is unbeatable if declarer guesses the diamonds right. It doesn't need any advanced play.

Unless someone tells me otherwise.

[edit] It fails on a club or diamond lead. On our table a spade was led.

You can make on a spade (or heart) lead,

1) Win ♠A
2) 2 rounds of trump
3) Diamond to king
4) Eventually draw last round of trump and run ♦10.

Certainly the defense can take diamond ace, 2 top clubs, and arrange a diamond ruff on a club or diamond lead, but a spade lead looks almost automatic.

100% beatable.

What are the rules for a lead out of turn again?

As you have noticed, a D or low C beats it, anything else and it makes. Double Dummy of course, but in this case I think unimportant.

Note that you don't have to put a lot of thought into that analysis (although I might recommend it). You don't need to ask the community; just click on the "GIB" button in the hand diagram.

Thanks. I just wanted reassurance that I wasn't speaking out of turn (as usual ) when I commented 'makeable' on the chatline. Of course it goes down on a minor suit lead, I realised that just after taking a second look at the deal.
