Bobby Fischer described Paul Morphy as "perhaps the most accurate player who ever lived." Which may explain why Morphy never lost with the Philidor Counter Gambit, an opening that requires pinpoint accuracy. One false move can lead to disaster. The following game is a good example of what happens when Black plays inaccurately. His 4...c6 was not the best move. Better would have been 4...Nc6, prepared to answer 5.d4 with 5...Be7.
