This may be a bit odd for a forum topic, but it seems certain places develop a distinct style of play when it comes to chess. The clearest example is Britain. For some reason or another, British masters on a whole don't have much regard for the opening. Keene, Miles and Basman (though not born in Britain, he resides there and competes in tournaments in the UK) definitely come to mind. Of course, not every game has an off-beat opening between those three, but a wide variety of curious (and even dubious) openings can be seen in the British championship tournaments.
After noticing this trend among the British players, I checked other national tournaments to see if there was a distinct style that had developed there. Some regions, mainly Eastern Europe, produce so many chess players that a variety of styles are employed. However, I did notice that tournaments in Latin American countries produced many hypermodern games reminiscent of the games played in the developing stages of the era.
Is there anything to be said for these trends? While I may be grasping at straws in the case of the Latin American tournaments, Britain really seems to have an "artistic" approach to the opening phase of the game.
