5 TROPHIES if you resolve this question first

sin function, Grishuk Alexander, Poor. There was definitely a chess player in singapore during 9/11. Probably not what you had in mind, but i think we have an answer.

yes lol well done the whole I didn't want to say too much but it was actually fischer when he made the anti-Semitic remarks while in the phillipines

Ah, makes sense. Honestly, i just checked for players in candidates and GA and NI where the only initials that could actually be used in a sentence. After sin, the rest was easy.

yes true but I think my question was a bit too difficult to understand but you were intelligent and didn't need all the info
my first is a function related to cos
my second are the initials of a chess player in the candidates (last name initial followed by the first one)
my third can be said about a chess player, as it can be said about a country or an animal. It generally isn't positive.
my whole is a place in the world quite near the other one where a famous and enigmatic chess player was during the September 11th attacks.
difficulty: medium, some will find it really easy, others difficult, first one to get it wins.
