{ You can watch the analyse of the game as a video aswell: https://www.youtube.com/watch?v=BVyRqUJszug The Lasker trap is named after Emanuel Lasker who was World Chess Champion for 27 years, from 1894 to 1921, the longest reign of any officially recognised World Chess Champion in history. The trap is unusual in that it features an underpromotion as early as the seventh move to win the game. } 1. d4 d5 2. c4 { The starting position of the Queen's Gambit. } 2... e5 { Black responded with the Albien Counter Gambit! Other Options for example would have been: } ( 2... c6 { the Slav Defense } ) ( 2... e6 { the Queen's Gambit declined } ) ( 2... dxc4 { the Queen's Gambit accepted } ) 3. dxe5 d4 { Gaining space and putting more pressure on White. White can no longer develop his knight to c3 now. [%cal Rb1c3] } 4. e3 $6 { This one is allready a mistake. } ( 4. Nf3 { attacking the e4 pawn a second time was the better move for white. [%cal Gf3d4,Gd1d4] } ) 4... Bb4+ ( 4... dxe3 5. Qxd8+ Kxd8 6. Bxe3 { was the variation white hoped for. This is not to recommend for black because now he is a pawn down, can no longer castle and doesn't have any counterplay. [%csl Ge5,Rd8][%cal Gb1c3,Ge1c1,Gg1f3,Gf1e2] } ) 5. Bd2 dxe3 { [%csl Gb4] } 6. Bxb4 $4 ( 6. fxe3 { was the only move for white, but after } 6... Qh4+ 7. g3 Qe4 { attacking the rook and the pawns on e3 and e5 at the same time [%cal Ge4h1,Ge4e5,Ge4e3] } 8. Nf3 Qxe3+ { [%csl Rd2][%cal Gb4e1] } 9. Be2 Bxd2+ 10. Qxd2 Qxd2+ 11. Nbxd2 Ne7 { black probably got a slight advantage because his next moves are pretty easy to find. He will play moves as c5 to gain some control over the center, Bf5, 0-0, Re8, Nc6 and Ng6 to attack the isolated pawn on e5. [%csl Re5][%cal Ge8g8,Gc7c5,Gc5d4,Gb8c6,Ge7g6,Gc8f5,Gc6e5,Gg6e5,Gh8e8,Ga8d8] } ) 6... exf2+ 7. Ke2 ( 7. Kxf2 Qxd1 { and black won the queen. } ) 7... fxg1=N+ $3 ( 7... fxg1=Q $2 8. Qxd8+ Kxd8 9. Rxg1 { and the position is about equal. [%csl Ge5,Gd8] } ) 8. Ke1 ( 8. Rxg1 Bg4+ { [%cal Gg4d1,Gd8d1] } 9. Kf2 Qxd1 { and black is up a queen. } ) 8... Qh4+ 9. Kd2 { traying to escape with the king to the queenside. [%cal Gd2c1] } ( 9. g3 $2 Qe4+ { [%cal Ge4h1,Ge4e1] } 10. Kf2 Qxh1 { and black is winning. } ) 9... Nc6 { Most analyses stop at this point because it's allready clear, that black is winning. I just want to show you two examples that where played in over the board games, so you get an understanding of blacks next moves. } 10. Qe1 { [%cal Ge1h4] } ( 10. Bc3 Bf5 11. Kc1 Qf2 12. Nd2 O-O-O { pinning the knight on d2 [%cal Gd8d1] } 13. c5 Nd4 14. Bxd4 Rxd4 { [%cal Gg8e7,Gh8d8] } 15. c6 Ne7 16. cxb7+ Kb8 { [%csl Gb7] } 17. Ba6 Rhd8 { was the game we were following and here White resigned because he has no defense left. [%cal Gd8d1] } ) 10... Qd4+ 11. Kc1 Nxb4 12. Qxb4 Qf2 { [%cal Gf2f1] } 13. Bd3 ( 13. Rxg1 Qxg1 { and black is winning. } ) 13... Qxg2 14. Qa4+ Bd7 { and again black is clearly winning. [%cal Gd7a4,Gg2h1] } 0-1
