1960 USSR Chess Championship

Mikhail Tal was missing, preparing for his world title match against Botvinnik. Paul Keres was in Cuba as part of a cultural delegation from Estonia. Spassky was in a moment of creative experimentation and got a bad place in the championship. He at this time was trying to play in a less academic style. As a result of his recent training period with Alexander Tolush, he often sacrificed material. The crowning moment for this attacking approach came in his winning against David Bronstein in the 16th round in a King's Gambit.[3]

After 15 rounds the leaders were Petrosian and Korchnoi with 11 points, Geller 10½ and Polugayevsky, Taimanov and Krogius 9. In the 16th round both leaders suffered. Petrosian had been unwell and lost to Averbakh. Korchnoi had a promising position against Bagirov, but in a crucial position where he should have played Bc3xTe1, with good chances, he unaccountably touched his a6 bishop, intending to make the capture with it on el. Naturally, he resigned on the spot. It was one of the most incredible mistakes of his career, and so Kotchnoi described the move:

My opponent had just taken of my rooks, and I was considering my reply.'First', I thought, 'I'll take his rook with my bishop, on the next move I'll move my other bishop'. The two bishops stood side by side, and I picked up the wrong one, the one that was attacking nothing. Without completing the move, I left the hall, leaving a thousand fans, who were tensely following my game, in a state of bewilderment, which shortly turned to grief.[4]

Such a blunder would have shattered a lesser man, but Korchnoi came back. He beat Krogius in the next round. The decisive game was an Alekhine's Defence in the 18th round encounter against Geller. Korchnoi with black pieces deferred development of his knight to c6, and outplayed Geller in complications to score a priceless victory.[5]
