The reserve event in the spring Monte Carlo tournament, won by Gereben with Karaklaic second, produced a number of entertaining and lively games. The New Zealand (now British by chess adoption) master Bob Wade had a good tournament, losing only to the two leaders—both amusing games in which he gave nearly, but not quite, as good as he got. Here is the game with Karaklaic.

White, R. G. Wade. Black. N. Karaklaic. Opening, Ruy Lopez. (Monaco 1967.)

1 P - K 4 P - K 4 2 Kt -K B 3 Kt - Q B 3 3 B - Kt 5 P - Q R 3 4 B x Kt . . The Exchange variation, which has recently had a mild vogue due to its adoption by Bobby Fischer. In it White concedes Black two bishops and a free game in return for the better pawn structure and a possible endgame advantage.

4... QPxB

50-0 P - B 3

6 P - B 3? . . . This cannot be right: the normal

move is P - Q 4 getting 4 pawns to 3 on the king's wing, while Black's pawn plus on the Q side is hard to mobilise. P - Q B 4! Naturally.

7 Kt - R 3 Kt 8 P - Q 4 BPxP 9 PP P x

10 P -X K 5 . . . P 10 Q x P, Q x Q; 11 Kt X Q will

leave Black the better ending because of his two bishops —he will no longer have trouble in using his extra queen's side pawn. The text is an attempt to use his advantage in development which just fails.

10 . . . B - Kt 5!

11 P x P P x P 12 Q X P B x Kt!

13 Q X P ... 13 Q x Q cis leaves Black an obvious endgame advantage. After the text, however, it looks 13 as if B White sill win—but Black has undercut him, . . . x Pl 14 Q X R B X R 15 B- R 6 Q- Q 4! Very fine. 16 Q x B ch, K- Q 2; 17 Q - Kt 7, R - K Kt 1 20W loses, so White's attack is over and Black takes command. The mating threat has gained the crucial tempo.

16 R x B 0 - 0 -0

17 B X B Kt - Kt 3 18 Q - Kt 7 . . . I think White is now too exposed

to be able to save the game. 18 . . . RXB

19 P -B 3 . . . the threat of R - K Kt 1 is devastat-

ing.

19 . . , R - Kt I 20 Q- B 6 Kt - B 5 eh!
