Olivares-Kanazawa had all the attributes of a great round: ebb and flow, all out effort, high drama. Loved it. Duran - Leonard I comes in second.
Sorry it took me a while to get to this, good friend who I hadn’t seen in a year passed through town. And our Greatest Round 13 of all time winner is ... Ruben Olivares-Kazuyoshi Kanazawa II.
