Tut, tut - the idea of countries buying chess players...just terrible! We'd never do such a thing in the United States, would we? (*Cough*) Anyway, they've done it in Azerbaijan with Arkadij Naiditsch, but to be fair it seems at least as much due to the German Chess Federation's failure to give Naiditsch (and professional chess in general) the sort of support he deemed appropriate, and over a long period of time.
The next chess olympiad is going to be extremely interesting!
