How do you make 11 tricks with this hand?

My partner and I like to practise with robots but using tournament hands.

The other day this hand cropped up.

https://tinyurl.com/yqy2fcaf

We got to 5C and went down one but when we looked at how Martel/Stansby played it they made 11 tricks although they were only in 2C.

We followed the play to trick 7 when Stansby led the AH from dummy and after winning claimed 11 tricks.

My partner and I have stared at this and can only see 4 more tricks but clearly Stansby can see 5 and the opponents agreed.

If somebody can explain how 5 more tricks can be made that would be very helpful.

Most likely just a mistake in inputting the data.

Stansby got a diamond lead based on the animation so as the other person noted, must be a documentation error. It would be good to actually locate the hand records to see if they are different from what BBO had.

You can see in the BBO traveller that it was only actually scored as 2+2, which agrees with the old records here (though the links to follow the play are broken), so it appears to just be the claim parameter which was input wrongly.

That's good to know. I thought I had lost my (bridge) mind :-) But the links to the results I nice since the way we play, if I don't export the hand while I am playing, I can't view it later.
