Tom Holroyd posted here a list of deals impossible under standard rules but possible with worrying back allowed. It's message number 242 from December 13, 2001. There are only 11 such deals in the first 20 million. If anyone can show a full solution to one of these (I haven't been able to solve any by hand yet), I would like to add it to the FC FAQ.
