This would allow one to make transpositions into book positions from >non-book positions. It can do this. What my current book logic requires is that the previous position must be a legitimate book position that is followed by the current book position (to allow the transposition.) If this fails, crafty will have to search normally. But if It then finds a move that returns it to a book position, all will be ok as it will then transpose in for its "next" search since this and that position are known book positions.
