"description": "Herkese Merhabalar, ilk handikaplı Go Turnuvası denememizi başlatıyorum. Turnuvalarımıza daha üst seviye oyuncularımızın katılmasıyla rekabeti canlandırma adına böyle bir şey denemeye karar verdim. \n\nTabii bir takım sorunlar da olmayacak değil. Örneğin turnuva OGS'de seviyesi belirlenmemiş oyunculara ne yazık ki açık olmayacak. Bu oyuncular hızlı birkaç maç yaparak seviyelerini belirledikten sonra turnuvaya katılabilirler. Bunu yapmak zorundaydım yoksa seviyesi henüz belirlenmediği için 20kyu olarak katılan 9Dan Pro oyuncularımız 9 handikap almak zorunda kalabilirdi. \n\nTurnuva Cumartesi sabah itibariyle başlayacak. Herkese başarılar dilerim!",
