Lichess tactic trainer: Find the best move for white.. Played by 16237 players.
I'm a new chess player and do not understand why the solution to this puzzle is Qc2+ instead of something like Rb8, Qf5, g4 I don't really understand what black could do here to save the Queen?
Especially when looking at puzzles, always look for forcing moves (like checks) because it forces your opponent to react and makes it easier to calculate for you. In this case, checks can be done by the queen or knight.
Nd5+ just blunders a Knight.
Qe4+ loses the Queen.
Qd3+ doesnโt accomplish much after a move like g6.
But Qc2+ not only has eyes on the King, but also the Rook on a4.
This forks the Rook and King and forces Black to lose their rook after Qxa4. Rb8 like you suggest does not win any material, and is not forcing your opponent to make a specific move. Hope that helps. ---
