Garry Kasparov's quote recommends that he has had a lot of experience with the KGB, the former Soviet Union's intelligence firm. This could indicate that he has had a great deal of contact with KGB officers, particularly colonels, either in his individual life or in his professional life. It might also suggest that he has had a lot of experience handling the KGB in some capacity, such as in his political advocacy or in his chess profession. It could also recommend that he has had a great deal of experience with the KGB in a more general sense, such as being aware of their activities and their presence in his life. Whatever the case, it is clear that Garry Kasparov has actually had a lot of experience with the KGB and its officers.
