For Klondike Solitaire, uncover face-down tableau cards, create empty columns for kings, and avoid moving cards to foundations when they are still needed as sequence connectors. Build descending alternating colors and track stock access under one-card or three-card draw rules. A move that reveals information is often stronger than a cosmetic foundation advance. For a legality issue, include deal, draw mode, tableau, stock, waste, foundations, client, and exact attempted move.
