Queen takes a long time ago with the right moves
Which moves?
really hard to expert!!!
To win the game be first to check the opponent king, even if it requires a sacrifice by a minor piece like a bishop or knight. Many of my puzzles follow this pattern: first sacrifice a minor piece to damage your opponent's pawn structure; follow with a check on the next move. In the middlegame, develop your pieces to execute this pattern and win many games.
