Conditional moves should only require a FEN string and move to play. They can be stored in text format to save space. Even with the most knightmarish FEN:
r1b1k2r/n1q1b1n1/p1p1p1p1/1p1p1p1p/1P1P1P1P/P1P1P1P1/N1Q1B1N1/R1B1K2R b KQkq - 49 999
This is only 85 characters of storage. A move cannot be longer than five characters, e.g. g7g8N for a promoted piece. All that is needed is the 'from' and 'to' squares, and the letter of the piece to promote to, if applicable.
So, worse case is 90 characters of storage per conditional move.
I currently have 23 messages in my Inbox. Messages have a 2000 character limit. Presumably, these could all be 2000 characters a piece.
Again, assuming that conditional moves take 90 characters a pop, I could store over 500
conditional moves in the same space that I have my messages.
