"description": "Want some game reviews? :)\nEvery player of this tournament will receive a review for one of his/her games (with the exception of disqualified players).\nMoreover, the winner may submit 2 more OGS games to be reviewed by the tournament director (ema) while the runner-up may submit 1 game.\n\nIt's an handicap-games tournament, so everyone has the chance to win (and get the reviews-prize ^^).\n\nEnjoy!",
