1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nxd4 $6 5. Qxd4 { There is a difference between getting your queen out too early and centralizing a queen.
A centralized queen is active and stable.
A queen that went out too early is easy to push around and gives tempi to the opponent.
White gets a good centralized queen after Nxd4. [%csl Gd4][%cal Yd4a7,Yd4h8,Yd4d8,Yd4a1,Yd4a4,Yd4e3,Yd4d1] } 5... e6 6. Be3 d6 7. Nc3 Nf6 8. f3 { typical move in different sicilians protects the central pawn on e4 and allows white to play g4 with a strong attack on the king side. [%csl Gf3][%cal Gf3e4,Rg2g4,Gf3g4] } 8... Be7 9. O-O-O O-O { [%csl Yf5,Yd5][%cal Ye4d5,Ye4f5] } 10. h4 $1 { White initiates his operations on the kingside. } 10... Bd7 11. g4 { White's attack is running pretty fast against the black king. [%csl Gg4][%cal Gg4f5,Gg4h5,Gh4g5] } 11... Rc8 12. h5 e5 { Finally black tries to force the queen out of d4, but e5 creates a backward pawn on d6 and a weak square on d5. [%csl Rd6][%cal Yd1d6] } ( 12... d5 { is generally a good liberating move that allows black to strike the center and activate his pieces. In many cases black uses a lot of his forces to support this advancement. In this case, d5 doesn't work. } 13. h6 g6 14. exd5 exd5 { [%cal Rg4g5,Rg5f6,Yd4g7,Yh6g7] } 15. g5 $1 $18 { [%csl Yg7][%cal Yd4g7,Rh6g7] } ( 15. Nxd5 $16 { [%cal Rd4h8,Bd5f6,Bd5e7,Rh6g7] } ) ) 13. Qd2 a6 14. g5 Ne8 15. g6 $5 { g6 tries to open up the kingside rapidly, but a better alternative could have been to get even more pieces into the attack. Paul Morphy style. } ( 15. Nd5 $1 { Nd5, followed by a move like Rdg1, could have increased the tension on the kingside, making it harder for black to the defend. Black doesn't have a clear way to generate counterplay white can benefit from this relocating his pieces with some impunity. [%cal Rd5e7,Rd5f6,Yd1g1,Yg1g7,Rf1d3] } 15... b5 16. Kb1 Be6 17.

In case the pawns disappear from the board, you'd get a King and Rook vs King and Bishop endgame, which is in most cases a theoretical draw. If you're not familiar with that endgame, make sure you search for it online, you'll need to know a pretty simple technique to be able to draw, and it is probably one of the most important endgames to study. } ) 41... a4 42. Qd1 $4 b3 { 0-1 Black wins. These are the positions that show us the importance of prophylaxis, an early Ka1 could have saved the day. [%cal Rb3c2,Rb3a2,Re4b1] } 0-1
