Just a wild guess: Edward Winter for #2?
Guess the author #5

Neither Smyslov nor Taimanov for #3. However, you have the correct nationality. An additional clue is that it is a trick question, intended to make it harder to get 100% right. In fact, two of the others are sort of trick questions (in a different way).
Here we go again. Who wrote the following?
[#1 Jon Speelman; #2 Hans Ree; #3 Tatyana Boleslavskaya; #4 Petrosian]
#1
#2
#3
#4
