Key: N-B4/Nf4
Played in informal tournament at Los Angeles Chess and Checker Club.
Harry Borochow (White) vs. Louis Millstein (Black)
French Defense: Burn Variation
Notes by the winner:
(a) Premature. Black should concern himself with complete development before attempting any counter-thrusts.
(b) Deliberately isolating this pawn to command K5 and QB5, and further hinder black's development of his Q-side pieces.
(c) P-KN4 instead looks very tempting, but after 13 … Q-K3 the ensuing complications are difficult to fathom. I therefore chose the restraining move, which prevents Q-K3.
(d) It is necessary for Black to move his Kt, and this cannot be accomplished without first weakening the K side. 14. … P-KR3 would be met by P-KN4 with an overwhelming attack.
(e) More crushing is 18. P-R6ch putting Black's KR completely out of play but in view of the interesting complications that arise, from the text, I chose PxP.
(f) 19. … KxR leads to many interesting variations. For example 20. N-N5 BxN; 21. R-Rch K-N; 22. PxB winning. Or 20. … B-K3; 21. NxNPch K-N2; 22. R-R PxN; 23. Q-R6ch K-B2; 24. Q-B4 (threatening NxB followed by R-R7ch; as well as N-N5ch etc.) N-Q4 (forced); 25. N-Q6ch K-N; 26. Q-R2 Q-K2; 27. BxP with ensuing complications problematical for the sacrificed piece, which of course was not essential for WHite. Or White might go astray as follows: after 23. … K-B2; 24. N-Q6ch K-K2! (Not QxN; 25. QxPch K-K2; 26. R-R7ch K-Q; 27. QxBch K-B; 28. B-B5! Q-B5ch; 29. K-Q K-N! (not QxB; 30. Q-R8 mate;) 30. Q-Q8ch B-B (N-B is met with BxB;) 31. P-KN3 Q-B6ch; 32. K-B P-R3; 33. BxB NxB; 34. Q-B7ch K-R2; 35. QxNP mate) 25. Q-B4 Q-KN!; with continuation difficult to fathom.
(g) K-K2 leads to immediate loss, and B-B4 permits Q-K5 mate.
(h) Losing at once, though with B-K3; 23. Q-K5ch K-N; 24. NxB QxQ; 25. PxQ PxN; 26. BxP, etc., with an easily won position.
(i) If 23. … PxN; 24. QxPch K-B; 25. Q-Q6ch K-N; 26. R-K B-Q2 (if N-Q4; 27. Q-N6ch and R-K8 mate;) 27. R-K7 B-K (Q-R4; 28. Q-B6 forces mate;) 28. B-N6 wins, as it threatens Q-K6ch followed, if K-B; by R-K7ch, etc.
