Assassins are all about controlled aggression. They tend to play sharp openings (especially 1.e4 as white) and look to attack the opponent's King. But their attacks are not wild or careless - everything is still governed by the objective demands of the position and exact calculation. Assassins tend to play "against the pieces" rather than "against the opponent". They won't alter their own play to try to take advantage of the opponent's psychology.
Robert J Fischer is an Assassin
Robert J Fischer Bobby Fischer (1943-2008), the eleventh World Chess Champion, was one deadly Assassin. One of the most dominant players of all time, the American became a grandmaster at the age of only fifteen and eventually took the world championship in a 1972 match with Boris Spassky. Fischer's perfect composure, along with accurate calculation and great will to win, caused his opponents to crumble. Fischer's opening repertoire was very limited, but also very sharp and very well prepared. All in all, Bobby Fischer was a chess machine long before actual chess engines could play at anywhere near that level.

Trifft sogar auf die Eröffnungen zu. Außer, dass dann der gute Bobby Fischer doch noch ein Stückchen stärker als ich gespielt hat.
