B. Spassky Wins World Championship
A new world champion was crowned when challenger Boris Spassky, 32, succeeded in wresting the title from Tigran Petrosian, 40, by the score of 12½ pts. to 10½. Spassky won the 4th, 5th, 8th, 17th, 19th and 21st games, Petrosian the 1st, 10th, 11th and 20th, with the other 13 games drawn. Petrosian had held the title since 1963 when he defeated M. Botvinnik, and successfully defended it against Spassky in 1966.
This match must be considered a great one in the long history of the championship both from the caliber of play, the clash of dissimilar styles, ideas and temperaments, and the closeness of the score throughout, which kept the chess world on edge for two months.

(a) With his Q-side pawn majority, and a QRP target, White has the edge.
(b) An adventure that does not turn out well. Simply the conservative 21. … QR-Q1.
(c) If 24. … BxB; 25. R-Q7 R-KB1; 26. N-Q6.
(d) All this to gain time on the clock before adjournment, as Black must continue, because of the state of the score, in the hope of a slip by White.
