One of the greatest feeling on a game of chess, is sacrificing your Queen on purpose so that once your opponent captures it, you deliver a devastating tactic to win the game. Of course, we don't want to typically give our Queen away but we must be prepared for anything if it means winning the game.
A queen sacrifice is always worth it if you can force checkmate. Sometimes it's also worthwhile if you have good compensation in the form of other well-coordinated pieces.
Black has incredible pressure on the d4 pawn, but Black's king cannot move and is in great danger. Can you find a powerful sacrifice that forces mate in two for White?
If Black's rook blocked the check on c7, White would play Qxc7 checkmate. Now that the b-file is open, deliver checkmate!
