I have heard the phrase, Zos. Somehow, however, I never equated a trick with cheating. Thinking about it, a cheat is someone who takes more than his due, and even the Devil is due exactly what he has bargained for. Whereas a trick -- a really good trick -- takes nothing from us (except, perhaps, the chains of ego).
I don't think baked bread has any live yeast remaining in it, so . . . oh, wait a minute, the dog! Tricky, I suppose, but then Giraldus of Einsiedel cheated the dog to trick the Devil. Interestingly, Longfellow's legend reminds me of this verse:
"For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet: The woman was a Greek, a Syro-Phoenician by nation; and she besought him that he would cast forth the devil out of her daughter. But Jesus said unto her, Let the children first be filled: for it is not meet to take the children's bread, and to cast it unto the dogs. And she answered and said unto him. Yes, Lord: yet the dogs under the table eat of the children's crumbs. And he said unto her, For this saying go thy way; the devil is gone out of thy daughter. And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed" (Mk 8:25-30).
Do you suppose Longfellow meant to suggest that, in tricking the Devil, ol' Giraldus took on a huge debt to the "dog?" In that Longfellow was quite well versed in the scripture, I wouldn't put it past him to have been suggesting that the bridge, all tolls, and all compound interest, now belongs to the "dog." Of course, this reminds me of yet another verse, but I'll just provide the citation: Mt 18:23-35.
Tricksy, ol' Longfellow. Thanks, Zos!
