If you want to do it right, it is. First, you need a regulation board, pieces and clock which runs about $50. Then you need a membership to the US Chess Federation if you are going to play in sanctioned tournaments, and since you called chess a sport, you probably do. That is about 30/yr. Then you need training which varies from master to master, and they usually charge by the hour. Finally, you will need a subscription to the Chess Informant which is printed in Serbia which runs over $100/yr. Then there are club fees, entry fees, and then there is travel because tournaments are seldom held regularly in the city where you live. good luck. email me for more information.
