The queen is the most powerful piece on the chessboard. However, it is often a mistake to bring the queen out early. The reason is that there are many pieces on the board and it is often possible to attack the queen. I recently played a game of speed chess at chess.com. My opponent and I both had eight minutes on our clocks. My opponent brought his queen out early and lost quickly. My opponent was Erickthegreat of the USA who played black. Here are the moves of the game along with my commentary:
1. e4 d6
2. d4 e6
3. Nf3 b6
Black's third move prepares Bb7.
4. Nc3 Bb7
5. Bd3 g6
Black's fifth moves prepares Bg7.
6. 0-0 Bg7
7. Re1 Nd7
8. Bg5 Ne7
9. e5 dxe
My goal is to open lines of attack against black's uncastled king. Black should castle here instead of capturing my pawn.
10. Nxe5 Nxe5
11. dxe5 Qd4
Black wants to win my e-pawn. His queen and bishop both attack it. I only have my queen to defend it. However, his king is too exposed.
Black resigns. No matter how he responds, he loses his queen. Black loses quickly because he brings the queen out too early and fails to get his king to safety.
