It was in BBO "Bridge 4 hands" and unfortunately I am unsure either how to or whether it can be retrieved. I had control of the first 11 tricks taking the first Diamond trick with the Ace and running my remaining 5 diamonds and then running my 5 good Hearts next with the 3 as the last remaining Heart (which was taken by the Ace of Spades???) At the end of the hand you could clearly see that I should have had 11 tricks ....6 Diamonds and 5 Hearts but was given 10 for the score due to the Spade mistake.
