I've shown you chessplayers once or twice before like on the street, but these gentlemen in Kalemegdan Park are true enthusiasts. Check out the little cushion under the man in beige pants' derriere (Serbs have a mortal fear of catching cold), and it appears that the man with the bandaged hand is particularly concerned about the safety of his bag that he has draped over his arm.
And dig those purple chess pieces....
