Adrian modified FC-Pro to accept sequence moves with a specified number of cards for moves to empty stacks only. (where the number of cards cannot be deduced from the destination.)
I wrote an interface to process the Freecell Solver solution, and to generate moves that were acceptable to Freecell Pro.
This involved playing the entire solution move by move, transferring cards to the foundations, and keeping track of such cards.
This took about a 100 more E-mails between Adrian and I.
End Result
Integration of Freecell Solver with Freecell Pro is now working, and the "Solver Evaluation Edition" of FC-Pro was released.
