The Scottish games from the preliminaries continue. Game 47 is between Cobo of Cuba and Pritchett of Scotland. The Scot plays the Dutch Defence as Black and wins in 21 moves. Pritchett also annotates the game, and is scathing of a move his opponent (an IM) plays in the opening.

Co-author of the Siegen Chess Olympiad book David Levy makes his second appearance in Game 48 of the book, vs Hort of Czechoslovakia, a very strong GM. Levy claims to have missed gaining the advantage on move 15, and he goes on to lose in 32 moves. The opening was a Pirc Defence.

Game 49 of the Siegen Chess Olympiad book is between Cordovil of Portugal and Garcia of Cuba. A Sicilian Defence Scheveningen Variation, the player from Portugal adopts an unorthodox treatment in the opening and uncorks a great move with 14 P–K5!!, going on to win in 26 moves.

Game 50 in the book is between Camilleri of Malta and Johannessen of Norway. The Norwegian plays an offbeat Ruy Lopez opening and is swiftly put to the sword by his Maltese opponent. Additional notes from Andrew Whiteley (first reserve board at the Olympiad for England).

Game 51 of the Siegen Chess Olympiad book is between Ragnar Hoen of Norway and Grandmaster Miroslav Filip (playing in his 10th consecutive Olympiad) of Czechoslovakia. Filip outplays Hoen in the Breyer Variation of the Ruy Lopez. Notes by Filip (translated by Grandmaster Ray Keene OBE).

Page 100 of the Siegen Chess Olympiad book has pictures of the Australian Master Doug Hamilton (who secured a draw against Korchnoi in the tournament) and Heinz Schaufelberger of Switzerland, who didn't draw a single game at Siegen (+7, =0, -4).

Game 52 of the book is a fascinating tussle in the Pirc between Austrian IM Andreas Dückstein and the Icelandic IM Guðmundur Sigurjonsson. The game ends in a draw but is full of interest.

Game 53 is between International Masters Miguel Cuéllar of Colombia and Bob Wade, then representing New Zealand. The Colombian wins convincingly (incidentally in 1962 Cuéllar placed 22nd at the Stockholm Interzonal, but defeated both Efim Geller and Korchnoi in individual games).

Game 54 in the Siegen Chess Olympiad book is an easy win for the West German Grandmaster Wolfgang Unzicker, who was White against Estonian-born Ortvin Sarupu, representing New Zealand (he emigrated to New Zealand).

Game 55 of the Siegen Chess Olympiad book is between Grandmaster Milko Bobotzov of Bulgaria and International Master Kaplan of Puerto Rico (World Junior Chess Champion 1967). It was a win in under 25 moves for the Puerto Rican, who successfully essayed the Modern Benoni Defence.

Game 56 in the book is an instructive attacking game from West German GM Lothar Schmidt against Austrian Anton Kinzel. A Petroff, Schmidt's play won the brilliancy prize for the preliminaries section of the Olympiad; although it seems Grandmaster Ray Keene OBE was unimpressed with this award!

In the final game of the preliminaries section of the Siegen Chess Olympiad book, Game 57, Schmid is again White, and plays another instructive game, against Jón Kristinsson of Iceland, winning in 33 moves in the Ruy Lopez open variation. 🥳Onwards friends onto the finals!🥳

The fascinating cross table of how the teams in the Finals finished is actually given at the start of the Finals Section of the Siegen Chess Olympiad book.

So onto the finals! The first game is an anodyne draw between Spassky and Unzicker. Unusually Spassky is on the White side of a Ruy Lopez Breyer Variation. But it's all theory. It seems strange that Spassky acquiseced like this as White, perhaps it was due to the match situation.

The first six games of the Finals Section of the Siegen Chess Olympiad book all feature Spassky. This game, the second of the six, is another dull draw, all theory. Spassky was Black against Portisch of Hungary and played the Tartakower Variation of the Queen's Gambit Declined.

The third game of the Finals Section of the Siegen Chess Olympiad book sees Spassky as Black again, vs. Uhlmann of East Germany. Another Queen's Gambit Declined, and yet another draw, this time in 27 moves (Spassky allows a perpetual check). Notes by Raymond Keene Grandmaster Ray Keene OBE

The spate of Boris Spassky games from the Finals continues in the Siegen Chess Olympiad book. But now, after three consecutive draws, Spassky produces a win, as White, against Gheorghiu of Romania, in an Old Indian Defence (pages 111-112). Notes by Grandmaster Ray Keene OBE and David Levy.

Game 62 of the Siegen Chess Olympiad book is another Spassky win with White, against Yanofsky of Canada. The Canadian goes astray in the opening, and the 10th World Champion produces a faultless technical display to secure the full point. Notes by Raymond Keene Grandmaster Ray Keene OBE.
