One of my current tournament opponents was born in Bulgaria but currently lives & works in Budapest, Hungary (see July 21)
The Budapest Gambit is one of the least common gambits but still offers black a lot of interesting play. In the main line for example, White can easily fall into a trap that ends in checkmate very early in the game.
