- koka (deprecated)
It was explained in the past as ippon = 10 points, instant win, wazari = 7 points, yuko = 5 points, koka = 3 points. But since you cannot simply add the points (like wazari + koka = ippon)
So, now the scores are displayed
ippon, wazari, yuko, (warnings/penalties)
the yellow card is a warning, the second is a shido. so the penalty's are:
- hansoku-make (you have lost the match and are banned for the rest of the tournament)
but since the scoreboard cannot hold those penalties, it is a point for you opponent.
so if you have your second yellow card, your opponent 'scores' a yuko. Your third 'yellow card' gives your opponent a wazari and a fourth yellow card gives your opponent an ippon.
it does not matter how many yuko's you score, they won't become a wazari. If your opponent scores a wazari and you have like 4 yuko's, you are still in losing position. I hope this makes it a bit more clear. I have heard more people struggling with the scoring-system of judo.
