Notice the unorthodox strategy Morphy uses. Morphy vs Duke Karl / Count Isouard, 1858   (C41) Philidor Defense, 17 moves, 1-0 Back is highly tactical here. Najdorf vs Fischer, 1966  (E75) King's Indian, Averbakh, Main line, 31 moves, 1-0 Deflection is the main theme in this game. M Hoffmann vs L Winants, 2004 (E11) Bogo-Indian Defense, 50 moves, 1/2-1/2 Black should have maneuvered behind the ranks a little. Gulko vs Kasparov, 1981  (A65) Benoni, 6.e4, 37 moves, 1-0 Kasparov hung a piece at the start of the middle game. Kasparov vs X3D Fritz, 2003  (D45) Queen's Gambit Declined Semi-Slav, 36 moves, 1/2-1/2 5 games
