"description": "ทัวนาเมนต์นี้อยากให้เป็นการแข่งขันที่ไม่นานขนาด Correspondence แต่ก็ไม่ถึงขนาด Live จริงๆ ซึ่งการแข่งจะให้ผู้เล่นได้ชิวๆ โดยที่สามารถเล่นได้ทั้งวัน พักกินข้าวได้ อาบน้ำ ทำงาน แล้วกลับมาเดินหมากใหม่ได้ โดยจะให้ผู้เล่นมีเวลาคนละ 25ชม.ในการพักรวมๆกัน\n\nรายละเอียดจะเป็น Byo-Yomi ถ้าผู้เล่นเดินหมากอยู่ตลอด เวลาก็จะไม่ลด พูดง่ายๆคือผู้เล่นไม่สามารถทิ้งเกมไปเกิน 1 วันหรือ 25ชม.ได้ ถ้าถึงกำหนด อย่างไรผู้เล่นก็ต้องกลับมาเดินหมากจนจบ โดยที่มีเวลาให้เดินตาละ 5 นาที ซึ่งไม่ทำให้แพ้เวลาแน่นอนถ้ารักษาเวลาได้\n\nเวลาแบบนี้ทำให้ผู้เล่นเกิดความคิดและการวางแผนที่ต่อเนื่อง ไม่ลืมกลยุทธที่วางไว้ และไม่เบื่อกับการรอคู่ต่อสู้นานเกินไปอีกด้วย",
