i didnt have time to see if someone find the good solution but let's have fun in my answer

if u notice something u already read ... it's pure coincidence ... of course (thanks Victor Mollo for making me so happy reading u ...)
the robber was completely unfair as the hideous hog was playing with papa the greek , against the rabbit and karapet the armenian ... still there was some kibbitz thougth u coudnt expect to see a close robber ... and the beginning was that so , karapet got squeeze 2 times in a row and led a wrong ace against a slam . hopefully the rabbit find ways to play 2 partial in 2S and 2H was cold for game but he still was happy to do his contract just made so the robber was closer after all .
after a couple of more deals here come this hand
the rabbit was holding
4
9542
A97654
A6
the auction bring the table to a 5D contract the more karapet was bidding his hand the more he was depressed knowing the rabbit hardly find ways to 11 tricks
in any case the lead by the hog was Q of S and the dummy comes as show
AK9
A103
KJ
K8432
the rabbit after having some look at the dummy suddenly realize he didnt know where he put the key of his house and was really thinking about it while he was calling A and then K of S , he had nothing to throw but still .. on his K of S he throw the 6 of C when suddenly some Kibbitz react ... the rabbit looks at what he played and he sees the Ace of C instead of the 6 ... the hog that we didnt hear for now quite some time (it was unusual... ) was surprisingly kind to the rabbit giving him permission to took back his card "dear friend i would never take advantages of something like that pls do what u want" , on the other side , papa of course was completely unhappy , he knew the rules and knew the card is played , everyone quite agree on that and the rabbit thougth he wasnt a good player would certainly not accept that offer as he also know the rules . after that the play should continue and the the rabbit decided he should try to ruff as many things as possible so at trick 3 he decided to ruff a S go back in hand with the K of C (thougth the rabbit was not genious he was quite happy enough to note he hopefully dont discard the 6 of C at that point) , ruff a C (as papa first hesitate on what to do and decide to play small H) go back in dummy again with a D to the K when he notice the Q, ruff another C (papa took some time again to throw a H) and play a H , at that time someone come to him with the key of his house he thougth he lost a while ago he was so relieved and was kinda forgeting the play so call a small H , papa playing low immediately . "are u sure u're playing low my DEAR friend rabbit u already pay enough with ur previous mistake , maybe it's enough ..." hog said . but the rabbit was just too much happy the key was back and didnt mind much the play , while papa was looking at the hog with an angry face , in any case it was played the rules said...in hand now whatever black card the hog migth play now , the rabbit already got 7 tricks ,and the ace of H and 3 more trumps will just work enough to reach 11 ...

PS : english not good enough to have more fun , hope it's readable thougth , i repeat , it's a nice hand , i dotn think throwing the Ace of C was an obligation thougth u can find other way i believe
