How to unlock the Amateur of FreeCell Solitaire achievement in Solitaire - Definitive Guide
As the description says, you need to win a game of Freecell without ever using to undo a move. Unlike Klondike, there's no luck involved here. Freecell is all about proper planning to manage your cards and not get stuck. Even so, some deals are way easier to manage and figure out than others.
Stack as many cards as you can but always try to shift them to smaller columns whenever possible to avoid a single column becoming extremely long. Only put cards up in the cells when you have no other moves, and make sure what you put up there either opens up a really key move or two, or that the cards in the cells can come back out shortly after. You definitely want to aim to clear out a single column of cards as soon as possible, since that effectively doubles the amount of cards you can move.
Much like chess, you should be looking 3+ moves ahead. Don't make a move until you see what move that opens up, and then what move that opens up, and so on. It may seem complex on paper but in reality you pretty much just want to do a dry run in your head first to see what domino effect your move will have. Check 3-5 moves out ahead of yours and if you're still in good shape, proceed. If your move results in 3-4 cards in the cells and nothing much opened up, then you should probably reconsider that path.
You've got 5 games to win, so it's pretty likely during that time that you'll get a good deal with a pretty easy set-up where the aces and twos are easy to get to and you can just start adding stuff to the piles to free up space. Keep at it and you should be able to win a game without undoing pretty easily.
