Victor Korchnoi plays a great game nearly everytime but some games stand out. Efim Geller was just off World Champion standard himself but here he gets totally defeated by a series of brilliant moves. This game was in the now defunct Soviet Union Championship which was said to be stronger than any top international tournament played in the West.
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Bg5 e6 7.Qd2 Be7?! [7...a6 This is the famous Najdorf Variation of the Sicilian Defence the most common way to play the Sicilian Defence.]
8.0-0-0 0-0 9.f4 e5 10.Nf3 [10.Nxc6 bxc6 11.fxe5 dxe5 12.Qxd8 Rxd8 13.Rxd8+ Bxd8 14.Bc4 h6 15.Bd2= a draw offer often results from this line.]
10...Bg4 11.h3 Bxf3 12.gxf3 Nd4 13.fxe5 dxe5 14.Rg1 Nxf3 15.Qf2 Qb6! 16.Be3 Nd4 17.Rxd4!! Some moves are unlikely, some obvious, this is an ofcourse type of move which once seen looks obvious but before seen, wouldnt occur to most people.
17...exd4 18.Bxd4 Qd8 [18...Qe6 ]
19.Nd5! Putting the pressure on the Knight at f6 and indirectly towards the g7 square. Efim defends manfully but the position is close to lost.
19...Ne8 20.Qg3 f6?? This move looks like it defends but looks can be deceptive. [20...Bh4 21.Qf4 (21.Qxg7+ Nxg7 22.Rxg7+ Kh8 23.Rxf7+ Kg8 24.Rg7+ Kh8 25.Rd7+ Kg8 26.Rg7+ Kh8 and a draw is the best on offer, White is just too far behind in material, and allowing Bf6 could even lose.) 21...Kh8 22.c3 Rc8 23.Kb1 Rc6 24.Bd3+/- ]
21.Bc4! Rf7 [21...Kh8 22.Nf4 Qxd4 23.Ng6+ hxg6 24.Qh4# ]
22.Nf4 Bd6 23.Bxf7+ Kxf7 24.Qb3+! Ke7 25.Bxf6+!! This must rank as one of Victors favourite moves- if not why not it is sublime. The Queen is lost or if the obvious moves 25...Kxf6 26.Qe6# or 25...Nxf6 26.Rxg7+ Ke8 27. Qf7# or 25... gxf6 26.Qe6+ Kf8 27.Rg8# 1-0
