{ You can watch the analyse of the game as a video aswell: https://www.youtube.com/watch?v=ZIewHg8obDE The Siberian Trap is a chess opening trap in the Smith-Morra Gambit of the Sicilian Defence. After a series of natural moves white can lose a queen. The name appears to result from Boris Schipkov of Novosibirsk in southwestern Siberia. } 1. e4 c5 { The starting position of the Sicilian Defence. } 2. d4 cxd4 3. c3 { White goes into the Smith-Morra Gambit, willing to sacrifice some material for fast developing and open lines, he can later use for an attack. } 3... dxc3 { Black accepts the gambit. } ( 3... d3 { is the most common way to decline the gambit. } ) 4. Nxc3 { White will now often play the same moves irrespective blacks move. His plan is to play Nf3, Bc4, 0-0, Qe2, Rfd1, Be3 and Rac1. [%cal Gg1f3,Gf1c4,Ge1g1,Gd1e2,Gc1e3,Gh1e1,Ga1c1] } 4... Nc6 5. Nf3 e6 6. Bc4 Qc7 { I personally don't like the queen move because of any Nb5 threats, so I just want to show you an other line for black: } ( 6... d6 7. O-O Nf6 8. Qe2 Be7 9. Rd1 { [%cal Re4e5] } 9... e5 { is similar to the Scheveningen Variation and about equal. } ) 7. O-O Nf6 8. Qe2 { Whites plan is to push the pawn to e5, gaining a tempo on the knight on f6 and fixing the weakness on d6, so one of whites pieces could potentially come to the square later in the game. [%cal Re4e5] } ( 8. Nb5 { was an other option for white. For example } 8... Qb8 9. e5 Ng4 ( 9... Nxe5 $2 10. Nxe5 Qxe5 11. Re1 { and white got huge compansation for the two pawns. Turn on the engine and play some moves by yourself to understand how hard it is to defend as black allready. } ) 10. Bf4 a6 ( 10... Ngxe5 $4 { would be a huge blunder because of } 11. Nxe5 Nxe5 12. Bxe6 $3 dxe6 13. Rc1 { and white is threatening Nc7, then he could take the knight on e5 and the rook on a8 is still hanging. On top of that the black king is still in the middle of the board with open lines against him. White is clearly winning. [%cal Gb5c7,Gf4e5,Gc7e8,Gc7a8] } ) 11. Nbd4 { White is willing to sacrafice another pawn } 11... Ncxe5 ( 11... b5 12. Nxc6 dxc6 13. Bb3 { and black is up a pawn, but his pieces aren't developed while white is ready to attack. } ) 12. Re1 d6 13. h3 Nxf3+ ( 13... Nxf2 14. Kxf2 Nxc4 15. Rc1 b5 16. b3 { and even if black is up 3 pawns white got a huge compansation. } ) 14. Nxf3 Nf6 15. Nd4 { and even if he's up two pawns black has some real difficultys to face. The computer thinks that white is allready better. } ) 8... Ng4 $1 9. h3 $4 { This move was played nearly 1.000 times in Lichess online games, unfortunately it loses the game right at the spot. } ( 9. Nb5 { was whites best move in the position. } 9... Qb8 { black threatens 10... a6 11.Nc3 Nd4! so white has to act right away } ( 9... Qd8 $2 { and suddenly black is in trouble because of } 10. Bf4 d6 11. Rfd1 ) 10. h3 h5 11. hxg4 ( 11. g3 Nge5 12. Nxe5 Nxe5 13. Bf4 a6 { and white got some compensation for the pawn. I think that the chances are roughly equal in this razor sharp position. } ) 11... hxg4 { is similar to the Fishing Pole Trap. Black is better. For example: } 12. Nh4 ( 12. Nd2 Qh2# ) ( 12. g3 gxf3 13. Qxf3 Ne5 14. Qb3 a6 15. Nc3 b5 16. Be2 b4 17. Na4 Bb7 { and black will start a huge attack against whites king. The computer gives it allready as nearly +3 for black. [%cal Gg7g5,Gg5g4,Ge5f3] } ) 12... Rxh4 13. g3 Rh8 { and black is up a pawn, got the open h file and some good moves to come like Ne5-f3 or a6 and b5. [%cal Gc6e5,Ge5f3,Ga7a6,Gb7b5] } ) ( 9. Bb3 $4 { loses again to the move } 9... Nd4 $3 ) ( 9. Rd1 $6 Bc5 { and black is well developed and is up a pawn, so I think black is better. } ) 9... Nd4 $3 { White resigned because he will lose the queen after } 10. hxg4 ( 10. Nxd4 { is even worse because of } 10... Qh2# ) ( 10. Qd1 { doesn't help because of } 10... Nxf3+ 11. Qxf3 Qh2# ) 10... Nxe2+ 11. Bxe2 0-1
