[Event "Paris"] [Site "?"] [Round "0"] [White "Morphy"] [Black "Anderssen"] [Result "1-0"] [ECO "B01"] [Opening "Scandinavian: 2...Qxd5 3.Nc3"] 1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. d4 e5 {A mistake since opening up the position will favor the side who is better developed and in this case it's to White's advantage. 4...Nf6} 5. dxe5 Qxe5+ 6. Be2 Bb4 7. Nf3 {White shows a deep understanding of the position. By giving up a pawn he will gain the advantage of having his pieces developed.} 7... Bxc3+ 8. bxc3 Qxc3+ 9. Bd2 Qc5 10. Rb1 { White has developed four pieces to Black's one due to the sacrificed pawn.} 10... Nc6 11. O-O Nf6 12. Bf4 O-O {12...Nd5 would allow White to win a piece.} 13. Bxc7 {White stands much better since he has regained his sacrificed pawn while keeping his lead in development.} 13... Nd4 14. Qxd4 Qxc7 {14...Qxc2 With the idea of attacking both bishops would backfire after 15.Bc4 when White hangs on to his extra piece.} 15. Bd3 Bg4 16. Ng5 Rfd8 { 16...Bh5 17.Ne4 Nxe4 18.Qxe4 Bg6 19.Qxb7 when White is a pawn ahead.} 17. Qb4 { 17.Bxh7+ Nxh7 18.Qxg4 Nxg5 19.Qxg5 Qxc2 20.Rxb7 Qxa2 allows Black to keep the material even.} 17... Bc8 {A sad move but the only move that allows Black to keep the material balance. 17...b6 18.Nxh7 Nxh7 19.Qxg4 17...Rab8 18.Nxh7 Nxh7 19.Qxg4} 18. Rfe1 {White has a big advantage due to his better development.} 18... a5 19. Qe7 Qxe7 {19...Rd7 Here White has a forced mate in two.} 20. Rxe7 {The exchange of queens has increased White's advantage due to his rook being on the seventh rank.} 20... Nd5 { 20...Rf8 21.Bc4 would force Black to part with his f-pawn.} 21. Bxh7+ { 21.Rxf7 h6 when Black would win material because of the double attack on both the White rook on f7 and the knight on g5.} 21... Kh8 22. Rxf7 Nc3 23. Re1 Nxa2 24. Rf4 { With the idea of catching the Black king in a mating net after a future Rh4.} 24... Ra6 25. Bd3 {Black resigned since the further loss of material is unavoidable. White threatens 25.Nf7+ winning the rook on e8 and 25.Bxa6.} 1-0
