Begin by examining the entire layout — the stock, tableau columns, and foundations (organized by suit). Your ultimate goal is to move all cards to the foundation piles in order from Ace to King.

Prioritize moves that uncover hidden cards; revealing a face-down card, especially an Ace or high-value card, should be your first choice.

Aim to clear a tableau column whenever possible — empty columns are incredibly valuable. You can place a sequence of cards starting with a King into an empty column, allowing for greater flexibility and a potential major reshuffle.
