1. d4 Ng8f6 2. c4 e6 3. g3 d5 4. Ng1f3 Bf8e7 5. Bf1g2 O-O 6. Qd1c2 Nb8c6 7. O-O Nc6b4 {so far so good. the white king is now nicely tugged away in a fianchettoed corner, but the queen side is still in starting position. queen chasing seems reasonable, hoping to develop now faster than white.} 8. Qc2b3 c5 9. dxc5 Be7xc5 10. Bc1g5 dxc4 11. Qb3xc4 b6 12. Nf3e5 Bc8a6 {the last queen chaser and development move. i was feeling happy now, even though blacks queen is now exposed in the center and the minor pieces always make me nervous, so close to the king...but whites pieces seem to be nicely split} 13. Qc4b3 Ba6xe2 {jump into the cold water: this pawn grabbing allows white to develop with tempo...} 14. Rf1e1 Bc5xf2 {the reason for the post: the double bishop attack. was one of the moves made with a shaky hand: not sure, if correct...it involves a check and breaks up the kings defense, so i thought this was justified...} 15. Kg1xf2 Qd8d4 {development with check-tempo. now the next positions are very difficult and am not sure, whether the best route was taken. the idea was, to keep white busy while positioning blacks pieces on good squares...} 16. Bg5e3 Qd4xe5 17. Kf2xe2 Qe5b5 {this is called the 'queen pendulum, 1st step...} 18. Ke2f3 Ra8d8 19. Nb1c3 Qb5h5 {and this is queen pendulum, 2nd step: the queen swings around to check from different diagonals.} 20. Kf3f2 Nf6g4 {by now the two heroic bishops are dead - lets say sacced - and the knights have to take over: you see now indeed six consecutive knight moves by black...} 21. Kf2f1 Ng4xh2 22. Kf1g1 Nb4d3 23. Re1e2 Nh2g4 24. Nc3e4 Ng4e5 25. Re2c2 Ne5f3 26. Kg1f1 Qh5f5 27. Ne4f2 Nf3d4 28. Be3xd4 Rd8xd4 29. Bg2e4 Rd4xe4 30. Qb3xd3 Re4e5 31. Qd3xf5 Re5xf5 {not clear, who got the edge here. i felt i let it slip away in the last moves, the attack should have been victorious, don't you think? happy for comments...} 32. Ra1d1 h5 {the pawn storm begins!} 33. Kf1g2 g5 34. Rd1h1 g4 35. Nf2d3 Kg8g7 36. Nd3f4 Rf8h8 37. Rc2c7 e5 38. Nf4d5 e4 39. Nd5f4 h4 40. Rc7xa7 h3 {the pawn on the a-file was sacced for the pawn storm to continue, not sure, if this was correct.} 41. Kg2f2 Rf5a5 42. Ra7xa5 bxa5 43. Kf2e3 f5 44. b3 Kg7f6 45. Nf4d5 Kf6e5 46. Nd5b6 Rh8d8 47. Nb6c4 Ke5f6 48. Nc4b2 Kf6g5 49. Rh1h2 f4 {as you see, the pawn storm became more like a fluffy wind: how to bring those guys through?} 50. gxf4 Kg5f5 51. Nb2c4 Rd8d3 52. Ke3e2 Kf5xf4 53. Rh2h1 Rd3g3 54. Rh1h2 e3 55. Ke2f1 Rg3f3 56. Kf1g1 Kf4g3 {what a mess: black all scrambled there and no real way through. this can certainly be handled better, the game is on the edge again! it looks so strong for black, but take away the rooks and sac the knight for a pawn: the white king is just happy to pick up the pawn-breeze later} 57. Rh2e2 Kg3f4 58. Nc4b2 Rf3g3 59. Kg1h2 Rg3f3 60. Nb2d1 Kf4e4 {this was it: didnt have time to analyze it fully, but i would have given up as well. now, without the rooks, knight and the e-pawn, whites king is powerless: the black king will take care of the two other pawns and come back to support the last part of the pawn storm...} 0-1
