4.1. The Problem

• Freecell Solver can move any number of cards as a sequence, and moves cards to the foundations when it sees fit.
• Freecell Pro tries to emulate Microsoft Freecell in its behaviour. Namely:
  
  1. Column-to-column moves were identified only by source and destination columns. (not the number of cards.)
  2. Cards that could be safely moved to the foundations, were indeed moved without an explicit move by the player or the solver.
• This behaviour is even present in the internals of Freecell Pro, which made adapting FC-Pro to use FCS even more difficult.
• This brought the following active discussion in the mailing-list.
