Nf3 d5 4. Bg5 {By this move order, White is trying to  force play into the Queen's Gambit Declined, while avoiding the Semi-Slav  (which could arise after 4 Nc3 c6), the Ragozin (which could arise after 4 Nc3  Bb4) and the Vienna (which could arise after 4 Nc3 dxc4).} h6 {Black replies  with his own tricky move.} 5. Bh4 {White offers a gambit.} (5. Bxf6 Qxf6 {  would lead to a variation of the Semi-Slav after} 6. Nc3 c6) 5... Bb4+ 6. Nbd2  {This tries to make use of White's move order to avoid transposition to more  usual lines.} (6. Nc3 dxc4 {leads to an improved version of the Ragozin  Defence, as Black has got in the useful ...h6 for free.}) 6... dxc4 7. Qc2 Nc6  (7... b5 {is the most thematic move, making White have to work to regain the  pawn or to demonstrate compensation.}) 8. e3 Qd5 9. Bxc4 Bxd2+ 10. Nxd2 {  White offers a pawn for good attacking chances.} (10. Qxd2 $4 Qxc4 {is not to  be recommended.}) (10. Kxd2 {is possible.}) (10. Kf1 {is also possible.}) 10...  Qxg2 11. O-O-O Qh3 $2 {This leaves Black in a lost position.} (11... Bd7 {  followed by ...0-0-0 leaves White better, but Black is still in the game.}) 12.  Bxf6 gxf6 13. Ne4 Qh4 14. Rhg1 $2 {This is not incisive enough.} (14. d5 $1 {  at once was stronger, when Black has no defence.}) 14... f5 $2 (14... Nb4 15.  Qa4+ Bd7 16. Bb5 Qxe4 17. Bxd7+ Kd8 18. Bxe6 fxe6 19. Qxb4 a5 {followed by ...  Ra6 is complicated.}) 15. Nc5 Ne7 16. d5 Qf6 $2 {After this, Black is  completely lost.} (16... exd5 {was perhaps a better try, but after} 17. Bxd5  Nxd5 18. Rxd5 {Black's position is grim.}) 17. dxe6 fxe6 18. Qb3 Qe5 19. Nxe6  Bxe6 20. Bxe6 c6 $2 {I overlooked that White can in fact take on b7.} 21. Qxb7  $1 Rd8 {I played this because I saw the pretty mate after Rb8 and wanted to  avoid that, but this falls into a simpler mate.} (21... Rb8 22. Qd7+ Kf8 23.  Qd8+ $1 Rxd8 24. Rxd8#) 22.
