Played on hazard. No opening I played against Marchand ever seemed to reach equality.
2. Nc3 Nc6; 3. Nf3 Nf6; 4. e4.
A bit unorthodox. Now 4...Bb4 should give Black a comfortable game.
4...d6?! 5. d4 ed; 6. N:d4.
Black is cramped.
6...Be7; 7. Be2 O-O; 8. N:c6!?
To be able to play Qc2 or Bd3 without ...Nb4.
8...bc; 9. O-O Nd7; 10. f4 Bf6; 11. Be3 Qe7; 12. Qc2 Bb7.
BLack has no good resource against the bind.
13. Bf3 Nb6; 14. b3 Rfe8; 15. Rae1 a5; 16. c5.
I've had tripled pawns before and survived, but why tempt fate?
16...Nd7; 17. Na4 Ba6; 18. Rf2 Bb5.
Still trying to simplify.
19. cd cd; 20. Rd2 Rad8; 21. Nb6 g6.
This loses a pawn, but I have faint hopes of counterplay.
22. a4 Ba6; 23. Q:c6 N:b6; 24. Q:b6 Bc8; 25. Q:a5.
White is ahead by two connected passed pawns. Only tactics can stop him!
25...Be6; 26. e5 de; 27. fe Bg5!
Most players would pronounce this a double error: it trades pieces while behind in material, and it trades a good Bishop instead of a bad one! But in such an extremity it is urgent to break up White's bishop pair. For the first time in the game, Marchand thought at length.
28. B:g5 Q:g5; 29. R:d8 R:d8; 30. Qc3 Rc8.
Counterplay bares its teeth.
31. Qe3 Qd8; 32. b4? Rc4.
Here White thought for a long time. Black's initiative is worth more than a pawn!
33. Rd1 Qe7; 34. a5 R:b4; 35. a6 Ra4; 36. Bb7.
Consolidating just in time. Black now advances steadily.
36...Bg4; 37. Rc1 Ra3; 38. Qf4 Bf5; 39. h3.
To free White's Rook from guard duty, but it weakens the King's field.
39...Qd8; 40. Kh2 Qb6; 41. Rd1 Qb3!
Simultaneously attacking the Rook and taking control of the third rank.
42. Rd2 Kg7; 43. Qh4 Qe3; 44. Qf6+ Kh6; 45. Rd1 Qf2!
Threatening 46...R:h3#. This is stronger than 45...B:h3, unless White falls into the trap 46. Qh4+ Kg7; 47. Q:h3?? Q:e5+; 48. g3 Qe2+. The more aggressive 45...Qe2 would allow perpetual check with 46. Qh4+.
46. Kh1! Qg3; 47. Q:f7 B:h3.
For White still has no mate, and 48. gh Q:h3+; 49. Kg1 Qg4+ costs a Rook.
48. Qf8+ Kg5; 49. Qf6+ Kh6; 50. Bf3.
Threatening 51. Qf8+ winning the Rook.
50...Ra2; 51. Rg1 Rf2.
Black's threats never end! This time it's 52...B:g2+; 53. B:g2 (or 53 R:g2 Rf1+ and mates) R:f6; 54. ef Qh4+.
52. Qf8+ Kg5; 53. Qe7+ Kh6; 54. Qf8+.
A snap decision in time pressure. It is tempting to advance a pawn instead, but after 54. a7 (or e6) B:g2+; 55. B:g2 Rf5! 56. Rf1 Rh5+; 57. Kg1 Qh2+; 58. Kf2 Qf4+ White must take the perpetual with 59. Kg1.
54...Kg5; 55. Qf6+ Kh6 1/2:1/2.
