whiteshark: "The following are seven games in which I have defeated players who were at least international master strength. All of these were rated tournament games played in real chess tournaments. My seven opponents were Browne, <Vucic>, Michael Shahade, Peters, Blumenfeld, Gruchacz and George Makropoulos. <All of them are at least international masters, although some of them did not have the title at the time that I defeated them.>
You will notice one common characteristic in all of these games. In every game, I sacrificed something. Some wag might suggest that I blundered and left all of those pieces en prise, but in reality, I did not. Also, in every game, I tended to win in the endgame or in the late middle game. Usually, when a player defeats a much stronger opponent, the stronger player fell into an opening trap or blundered early on. However, since I do not know openings, my best chance to win generally comes if I can somehow manage to survive until the endgame.
These are all good games. My game against Browne was published in the February, 1968 Chess Life. My game against Shahade was published in the New York Times, as I recall, but I did not save the clipping, so I cannot give the date. <However, my best and most interesting game was against International Master Mladen Vucic, in which I sacrificed my queen,> and that has not been published at all."
